This is an example.<\/p>\n<\/body>\n<\/html>\n\n<\/pre>\n\n
現(xiàn)在，如果你訪問(wèn)自己網(wǎng)站的根資源，你會(huì)看到example.php的內(nèi)容。這仍沒(méi)什么用，但你要清楚你要在以一種結(jié)構(gòu)和組織非常清楚的方式在開(kāi)發(fā)網(wǎng)絡(luò)應(yīng)用。<\/p>\n
為了讓Zend_View的應(yīng)用更清楚一點(diǎn)，，修改你的模板(example.php)包含以下內(nèi)容：<\/p>\n\n
\n\n\n<?php echo $this->escape($this->title); ?><\/title>\n<\/head>\n<body> <h1><a href="http://www.miracleart.cn/">国产av日韩一区二区三区精品,成人性爱视频在线观看,国产,欧美,日韩,一区,www.成色av久久成人,2222eeee成人天堂</a></h1>\n <?php echo $this->escape($this->body); ?>\n<\/body>\n<\/html>\n\n<\/pre>\n\n<p>現(xiàn)在已經(jīng)添加了兩個(gè)功能。$this->escape()類方法用于所有的輸出。即使你自己創(chuàng)建輸出，就像這個(gè)例子一樣。避開(kāi)所有輸出也是一個(gè)很好的習(xí)慣，它可以在默認(rèn)情況下幫助你防止跨站腳本攻擊（XSS）。<\/p>\n<p>$this->title和$this->body屬性用來(lái)展示動(dòng)態(tài)數(shù)據(jù)。這些也可以在controller中定義，所以我們修改IndexController.php以指定它們：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::loadClass('Zend_Controller_Action');\nZend::loadClass('Zend_View');\nclass IndexController extends Zend_Controller_Action \n{\n public function indexAction()\n {\n $view = new Zend_View();\n $view->setScriptPath('\/path\/to\/views');\n $view->title = 'Dynamic Title';\n $view->body = 'This is a dynamic body.';\n echo $view->render('example.php');\n }\n public function noRouteAction()\n {\n $this->_redirect('\/');\n }\n}\n?>\n\n<\/pre>\n\n<p>現(xiàn)在你再次訪問(wèn)根目錄，應(yīng)該就可以看到模板所使用的這些值了。因?yàn)槟阍谀０逯惺褂玫?this就是在Zend_View范圍內(nèi)所執(zhí)行的實(shí)例。<\/p>\n<p>要記住example.php只是一個(gè)普通的PHP腳本，所以你完全可以做你想做的。只是應(yīng)努力只在要求顯示數(shù)據(jù)時(shí)才使用模板。你的controller (controller分發(fā)的模塊)應(yīng)處理你全部的業(yè)務(wù)邏輯。<\/p>\n<p>在繼續(xù)之前，我想做最后一個(gè)關(guān)于Zend_View的提示。在controller的每個(gè)類方法內(nèi)初始化$view對(duì)象需要額外輸入一些內(nèi)容，而我們的主要目標(biāo)是讓快速開(kāi)發(fā)網(wǎng)絡(luò)應(yīng)用更簡(jiǎn)單。如果所有模板都放在一個(gè)目錄下，是否要在每個(gè)例子中都調(diào)用setScriptPath()也存在爭(zhēng)議。<\/p>\n<p>幸運(yùn)的是，Zend類包含了一個(gè)寄存器來(lái)幫助減少工作量。你可以用register()方法把你的$view對(duì)象存儲(chǔ)在寄存器：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::register('view', $view);\n?>\n\n<\/pre>\n\n<p>用registry()方法進(jìn)行檢索：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\n$view = Zend::registry('view');\n?>\n\n<\/pre>\n\n<p>基于這點(diǎn)，本教程使用寄存器。 <\/p>\n<p><strong>Zend_InputFilter<\/strong><\/p>\n<p>本教程討論的最后一個(gè)組件是Zend_InputFilter。這個(gè)類提供了一種簡(jiǎn)單而有效的輸入過(guò)濾方法。你可以通過(guò)提供一組待過(guò)濾數(shù)據(jù)來(lái)進(jìn)行初始化。<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\n$filterPost = new Zend_InputFilter($_POST);\n?>\n\n<\/pre>\n\n<p>這會(huì)將($_POST)設(shè)置為NULL，所以就不能直接進(jìn)入了。Zend_InputFilter提供了一個(gè)簡(jiǎn)單、集中的根據(jù)特定規(guī)則過(guò)濾數(shù)據(jù)的類方法集。例如，你可以用getAlpha()來(lái)獲取$_POST['name']中的字母：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\n\/* $_POST['name'] = 'John123Doe'; *\/\n$filterPost = new Zend_InputFilter($_POST);\n\/* $_POST = NULL; *\/\n$alphaName = $filterPost->getAlpha('name');\n\/* $alphaName = 'JohnDoe'; *\/\n?>\n\n<\/pre>\n\n<p>每一個(gè)類方法的參數(shù)都是對(duì)應(yīng)要過(guò)濾的元素的關(guān)鍵詞。對(duì)象(例子中的$filterPost)可以保護(hù)數(shù)據(jù)不被篡改，并能更好地控制對(duì)數(shù)據(jù)的操作及一致性。因此，當(dāng)你操縱輸入數(shù)據(jù)，應(yīng)始終使用Zend_InputFilter。<\/p>\n<p>提示：Zend_Filter提供與Zend_InputFilter方法一樣的靜態(tài)方法。<\/p>\n<p><strong>構(gòu)建新聞管理系統(tǒng)<\/strong><\/p>\n<p>雖然預(yù)覽版提供了許多組件（甚至許多已經(jīng)被開(kāi)發(fā)），我們已經(jīng)討論了構(gòu)建一個(gè)簡(jiǎn)單程序所需要的全部組件。在這里，你會(huì)對(duì)ZF的基本結(jié)構(gòu)和設(shè)計(jì)有更清楚的理解。<\/p>\n<p>每個(gè)人開(kāi)發(fā)的程序都會(huì)有所不同，而Zend Framework試圖包容這些差異。同樣，這個(gè)教程是根據(jù)我的喜好寫的，請(qǐng)根據(jù)自己的偏好自行調(diào)整。<\/p>\n<p>當(dāng)我開(kāi)發(fā)程序時(shí)，我會(huì)先做界面。這并不意味著我把時(shí)間都花在標(biāo)簽、樣式表和圖片上，而是我從一個(gè)用戶的角度去考慮問(wèn)題。因此我把程序看成是頁(yè)面的集合，每一頁(yè)都是一個(gè)獨(dú)立的網(wǎng)址。這個(gè)新聞系統(tǒng)就是由以下網(wǎng)址組成的：<\/p>\n<p><span style=\"color: #0000ff\">\/<br \/>\n\/add\/news<br \/>\n\/add\/comment<br \/>\n\/admin<br \/>\n\/admin\/approve<br \/>\n\/view\/{id}<\/span><\/p>\n<p>你可以直接把這些網(wǎng)址和controller聯(lián)系起來(lái)。IndexController列出新聞，AddController添加新聞和評(píng)論，AdminController處理一些如批準(zhǔn)新聞之類的管理，ViewController特定新聞和對(duì)應(yīng)評(píng)論的顯示。<\/p>\n<p>如果你的FooController.php還在，把它刪除。修改IndexController.php，為業(yè)務(wù)邏輯以添加相應(yīng)的action和一些注釋：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::loadClass('Zend_Controller_Action');\nclass IndexController extends Zend_Controller_Action \n{\n public function indexAction()\n {\n \/* List the news. *\/\n }\n public function noRouteAction()\n {\n $this->_redirect('\/');\n }\n}\n?>\n\n<\/pre>\n\n<p>接下來(lái)，創(chuàng)建AddController.php文件：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::loadClass('Zend_Controller_Action');\nclass AddController extends Zend_Controller_Action\n{\n function indexAction()\n {\n $this->_redirect('\/');\n }\n function commentAction()\n {\n \/* Add a comment. *\/\n }\n function newsAction()\n {\n \/* Add news. *\/\n }\n function __call($action, $arguments)\n {\n $this->_redirect('\/');\n }\n}\n?>\n\n<\/pre>\n\n<p>記住AddController的indexAction()方法不能調(diào)用。當(dāng)訪問(wèn)\/add時(shí)會(huì)執(zhí)行這個(gè)類方法。因?yàn)橛脩艨梢允止ぴL問(wèn)這個(gè)網(wǎng)址，這是有可能的，所以你要把用戶重定向到主頁(yè)、顯示錯(cuò)誤或你認(rèn)為合適的行為。<\/p>\n<p>接下來(lái)，創(chuàng)建AdminController.php文件：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::loadClass('Zend_Controller_Action');\nclass AdminController extends Zend_Controller_Action\n{\n function indexAction()\n {\n \/* Display admin interface. *\/\n }\n function approveAction()\n {\n \/* Approve news. *\/\n }\n function __call($action, $arguments)\n {\n $this->_redirect('\/');\n }\n}\n?>\n\n<\/pre>\n\n<p>最后，創(chuàng)建ViewController.php文件：<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nZend::loadClass('Zend_Controller_Action');\nclass ViewController extends Zend_Controller_Action\n{\n function indexAction()\n {\n $this->_redirect('\/');\n }\n function __call($id, $arguments)\n {\n \/* Display news and comments for $id. *\/\n }\n}\n?>\n\n<\/pre>\n\n<p>和AddController一樣，index()方法不能調(diào)用，所以你可以使用你認(rèn)為合適的action。ViewController和其它的有點(diǎn)不同，因?yàn)槟悴恢朗裁床攀怯行У腶ction。為了支持像\/view\/23這樣的網(wǎng)址，你要使用__call()來(lái)支持動(dòng)態(tài)action。<\/p>\n<p><strong>數(shù)據(jù)庫(kù)操作<\/strong><\/p>\n<p>因?yàn)閆end Framework的數(shù)據(jù)庫(kù)組件還不穩(wěn)定，而我希望這個(gè)演示可以做得簡(jiǎn)單一點(diǎn)。我使用了一個(gè)簡(jiǎn)單的類，用SQLite進(jìn)行新聞條目和評(píng)論的存儲(chǔ)和查詢。<\/p>\n\n<pre class='brush:php;toolbar:false;'>\n<?php\nclass

id="A-classic-tutorial-for-getting-started-with-Zend-Framework-development-zendframework">A classic tutorial for getting started with Zend Framework development, zendframework</h2> <p>This article talks about knowledge points related to getting started with Zend Framework development. Share it with everyone for your reference, the details are as follows: </p> <p>Zend Framework is released! Although still in the early stages of development, this tutorial highlights some of the best features available and guides you through building a simple program. </p> <p>Zend was the first to release ZF in the community. Based on the same idea, this tutorial was written to demonstrate the existing capabilities of ZF. Since this tutorial is posted online, I will update it as ZF changes so that it is as efficient as possible. </p> <p><strong>Requirements</strong></p> <p>Zend Framework requires PHP5. In order to make best use of the code in this tutorial, you will also need the Apache web server. Because the demonstration program (a news management system) uses mod_rewrite. </p> <p>The code for this tutorial is freely downloadable, so you can try it yourself. You can download the code from Brain Buld's website: http://brainbulb.com/zend-framework-tutorial.tar.gz. </p> <p><strong>Download ZF</strong></p> <p>When you start this tutorial, you need to download the latest version of ZF. You can use a browser to manually select the tar.gz or zip file to download from http://framework.zend.com/download, or use the following command: </p> <pre class='brush:php;toolbar:false;'> $ wget http://framework.zend.com/download/tgz $ tar -xvzf ZendFramework-0.1.2.tar.gz </pre> <p>Tip: Zend plans to provide its own PEAR channel to simplify downloads. </p> <p>Once you download the preview version, put the library directory somewhere convenient. In this tutorial, I renamed library to lib to have a concise directory structure: </p> <p><span style="color: #0000ff">app/<br /> Views/<br /> Controllers/<br /> www/<br /> .htaccess<br /> Index.php<br /> lib/</span></p> <p>The www directory is the document root directory, the controllers and views directories are empty directories that will be used later, and the lib directory comes from the preview version you downloaded. </p> <p><strong>Start</strong></p> <p>The first component I want to introduce is Zend_Controller. In many ways, it provides the foundation for the programs you develop, and it also partially determines that Zend Framework is more than just a collection of components. However, you need to put all the obtained requests into a simple PHP script before using it. This tutorial uses mod_rewrite. </p> <p>Using mod_rewrite is an art in itself, but luckily this particular task is surprisingly easy. If you are unfamiliar with mod_rewrite or Apache configuration in general, create a .htaccess file in the document root and add the following content: </p> <pre class='brush:php;toolbar:false;'> RewriteEngine on RewriteRule !/.(js|ico|gif|jpg|png|css)$ index.php </pre> <p><span style="color: #0000ff">Tip: One TODO project of Zend_Controller is to cancel the dependence on mod_rewrite. To provide a preview of the example, this tutorial uses mod_rewrite. </span></p> <p>If you add these contents directly to httpd.conf, you must restart the web server. But if you use a .htaccess file, you don't have to do anything. You can do a quick test by putting some specific text into index.php and accessing any path such as /foo/bar. If your domain name is example.org, visit http://example.org/foo/bar. </p> <p>You also need to set the path of the ZF library to include_path. You can set it in php.ini, or you can put the following content directly in your .htaccess file: </p> <pre class='brush:php;toolbar:false;'> php_value include_path "/path/to/lib" </pre> <p><strong>Zend</strong></p> <p>The Zend class contains a collection of frequently used static methods. Here is the only class you need to add manually: </p> <pre class='brush:php;toolbar:false;'> <?php include 'Zend.php'; ?> </pre> <p>Once you include Zend.php, you have included all the class methods of the Zend class. You can simply load other classes using loadClass(). For example, load the Zend_Controller_Front class: </p> <pre class='brush:php;toolbar:false;'> <?php include 'Zend.php'; Zend::loadClass('Zend_Controller_Front'); ?> </pre> <p>include_path can understand the organization and directory structure of loadclass() and ZF. I use it to load all other classes. </p> <p><strong>Zend_Controller</strong></p> <p>Using this controller is very intuitive. In fact, I didn't use its extensive documentation when writing this tutorial. </p> <p>Tips: The documentation is currently available at http://framework.zend.com/manual/zend.controller.html. </p> <p>I initially used a front controller called Zend_Controller_Front. To understand how it works, place the following code in your index.php file: </p> <pre class='brush:php;toolbar:false;'> <?php include 'Zend.php'; Zend::loadClass('Zend_Controller_Front'); $controller = Zend_Controller_Front::getInstance(); $controller->setControllerDirectory('/path/to/controllers'); $controller->dispatch(); ?> </pre> <p>If you prefer object linking, you can use the following code instead: </p> <pre class='brush:php;toolbar:false;'> <?php include 'Zend.php'; Zend::loadClass('Zend_Controller_Front'); $controller = Zend_Controller_Front::getInstance() ->setControllerDirectory('/path/to/controllers') ->dispatch(); ?> </pre> <p>Now if you access /foo/bar, an error will occur. That’s right! It lets you know what's going on. The main problem is that the IndexController.php file cannot be found. </p> <p>Before you create this file, you should first understand how the government wants you to organize these things. ZF splits the access requests. If you are accessing /foo/bar, foo is the controller and bar is the action. Their default values ??are index.</p> <p>If foo is a controller, ZF will search for the FooController.php file in the controllers directory. Because this file does not exist, ZF falls back to IndexController.php. No results were found, so an error was reported. </p> <p>Next, create the IndexController.php file in the controllers directory (can be set with setControllerDirectory()): </p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class IndexController extends Zend_Controller_Action { public function indexAction() { echo 'IndexController::indexAction()'; } } ?> </pre> <p>就如剛才說(shuō)明的，IndexController類處理來(lái)自index controller或controller不存在的請(qǐng)求。indexAction()方法處理action為index的訪問(wèn)。要記住的是index是controller和action的默認(rèn)值。如果你訪問(wèn)/，/index或/index/index，indexAction()方法就會(huì)被執(zhí)行。 (最后面的斜杠并不會(huì)改變這個(gè)行為。) 而訪問(wèn)其他任何資源只會(huì)導(dǎo)致出錯(cuò)。</p> <p>在繼續(xù)做之前，還要在IndexController加上另外一個(gè)有用的類方法。不管什么時(shí)候訪問(wèn)一個(gè)不存在的控制器，都要調(diào)用noRouteAction()類方法。例如，在FooController.php不存在的條件下，訪問(wèn)/foo/bar就會(huì)執(zhí)行noRouteAction()。但是訪問(wèn)/index/foo仍會(huì)出錯(cuò)，因?yàn)閒oo是action，而不是controller.</p> <p>將noRouteAction()添加到IndexController.php:</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class IndexController extends Zend_Controller_Action { public function indexAction() { echo 'IndexController::indexAction()'; } public function noRouteAction() { $this->_redirect('/'); } } ?> </pre> <p>例子中使用$this->_redirect('/')來(lái)描述執(zhí)行noRouteAction()時(shí)，可能發(fā)生的行為。這會(huì)將對(duì)不存在controllers的訪問(wèn)重定向到根文檔（首頁(yè)）。</p> <p>現(xiàn)在創(chuàng)建FooController.php：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class FooController extends Zend_Controller_Action { public function indexAction() { echo 'FooController::indexAction()'; } public function barAction() { echo 'FooController::barAction()'; } } ?> </pre> <p>如果你再次訪問(wèn)/foo/bar，你會(huì)發(fā)現(xiàn)執(zhí)行了barAction()，因?yàn)閎ar是action?，F(xiàn)在你不只支持了友好的URL，還可以只用幾行代碼就做得這么有條理?？岚?！<br /> 你也可以創(chuàng)建一個(gè)__call()類方法來(lái)處理像/foo/baz這樣未定義的action。</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class FooController extends Zend_Controller_Action { public function indexAction() { echo 'FooController::indexAction()'; } public function barAction() { echo 'FooController::barAction()'; } public function __call($action, $arguments) { echo 'FooController:__call()'; } } ?> </pre> <p>現(xiàn)在你只要幾行代碼就可以很好地處理用戶的訪問(wèn)了，準(zhǔn)備好繼續(xù)。</p> <p><strong>Zend_View</strong></p> <p>Zend_View是一個(gè)用來(lái)幫助你組織好你的view邏輯的類。這對(duì)于模板-系統(tǒng)是不可知的，為了簡(jiǎn)單起見(jiàn)，本教程不使用模板。如果你喜歡的話，不妨用一下。</p> <p>記住，現(xiàn)在所有的訪問(wèn)都是由front controller進(jìn)行處理。因此應(yīng)用框架已經(jīng)存在了，另外也必須遵守它。為了展示Zend_View的一個(gè)基本應(yīng)用，將IndexController.php修改如下：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); Zend::loadClass('Zend_View'); class IndexController extends Zend_Controller_Action { public function indexAction() { $view = new Zend_View(); $view->setScriptPath('/path/to/views'); echo $view->render('example.php'); } public function noRouteAction() { $this->_redirect('/'); } } ?> </pre> <p>在views目錄創(chuàng)建example.php文件：</p> <pre class='brush:php;toolbar:false;'> <html> <head> <title>This Is an Example</title> </head> <body> <p>This is an example.</p> </body> </html> </pre> <p>現(xiàn)在，如果你訪問(wèn)自己網(wǎng)站的根資源，你會(huì)看到example.php的內(nèi)容。這仍沒(méi)什么用，但你要清楚你要在以一種結(jié)構(gòu)和組織非常清楚的方式在開(kāi)發(fā)網(wǎng)絡(luò)應(yīng)用。</p> <p>為了讓Zend_View的應(yīng)用更清楚一點(diǎn)，，修改你的模板(example.php)包含以下內(nèi)容：</p> <pre class='brush:php;toolbar:false;'> <html> <head> <title><?php echo $this->escape($this->title); ?></title> </head> <body> <?php echo $this->escape($this->body); ?> </body> </html> </pre> <p>現(xiàn)在已經(jīng)添加了兩個(gè)功能。$this->escape()類方法用于所有的輸出。即使你自己創(chuàng)建輸出，就像這個(gè)例子一樣。避開(kāi)所有輸出也是一個(gè)很好的習(xí)慣，它可以在默認(rèn)情況下幫助你防止跨站腳本攻擊（XSS）。</p> <p>$this->title和$this->body屬性用來(lái)展示動(dòng)態(tài)數(shù)據(jù)。這些也可以在controller中定義，所以我們修改IndexController.php以指定它們：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); Zend::loadClass('Zend_View'); class IndexController extends Zend_Controller_Action { public function indexAction() { $view = new Zend_View(); $view->setScriptPath('/path/to/views'); $view->title = 'Dynamic Title'; $view->body = 'This is a dynamic body.'; echo $view->render('example.php'); } public function noRouteAction() { $this->_redirect('/'); } } ?> </pre> <p>現(xiàn)在你再次訪問(wèn)根目錄，應(yīng)該就可以看到模板所使用的這些值了。因?yàn)槟阍谀０逯惺褂玫?this就是在Zend_View范圍內(nèi)所執(zhí)行的實(shí)例。</p> <p>要記住example.php只是一個(gè)普通的PHP腳本，所以你完全可以做你想做的。只是應(yīng)努力只在要求顯示數(shù)據(jù)時(shí)才使用模板。你的controller (controller分發(fā)的模塊)應(yīng)處理你全部的業(yè)務(wù)邏輯。</p> <p>在繼續(xù)之前，我想做最后一個(gè)關(guān)于Zend_View的提示。在controller的每個(gè)類方法內(nèi)初始化$view對(duì)象需要額外輸入一些內(nèi)容，而我們的主要目標(biāo)是讓快速開(kāi)發(fā)網(wǎng)絡(luò)應(yīng)用更簡(jiǎn)單。如果所有模板都放在一個(gè)目錄下，是否要在每個(gè)例子中都調(diào)用setScriptPath()也存在爭(zhēng)議。</p> <p>幸運(yùn)的是，Zend類包含了一個(gè)寄存器來(lái)幫助減少工作量。你可以用register()方法把你的$view對(duì)象存儲(chǔ)在寄存器：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::register('view', $view); ?> </pre> <p>用registry()方法進(jìn)行檢索：</p> <pre class='brush:php;toolbar:false;'> <?php $view = Zend::registry('view'); ?> </pre> <p>基于這點(diǎn)，本教程使用寄存器。 </p> <p><strong>Zend_InputFilter</strong></p> <p>本教程討論的最后一個(gè)組件是Zend_InputFilter。這個(gè)類提供了一種簡(jiǎn)單而有效的輸入過(guò)濾方法。你可以通過(guò)提供一組待過(guò)濾數(shù)據(jù)來(lái)進(jìn)行初始化。</p> <pre class='brush:php;toolbar:false;'> <?php $filterPost = new Zend_InputFilter($_POST); ?> </pre> <p>這會(huì)將($_POST)設(shè)置為NULL，所以就不能直接進(jìn)入了。Zend_InputFilter提供了一個(gè)簡(jiǎn)單、集中的根據(jù)特定規(guī)則過(guò)濾數(shù)據(jù)的類方法集。例如，你可以用getAlpha()來(lái)獲取$_POST['name']中的字母：</p> <pre class='brush:php;toolbar:false;'> <?php /* $_POST['name'] = 'John123Doe'; */ $filterPost = new Zend_InputFilter($_POST); /* $_POST = NULL; */ $alphaName = $filterPost->getAlpha('name'); /* $alphaName = 'JohnDoe'; */ ?> </pre> <p>每一個(gè)類方法的參數(shù)都是對(duì)應(yīng)要過(guò)濾的元素的關(guān)鍵詞。對(duì)象(例子中的$filterPost)可以保護(hù)數(shù)據(jù)不被篡改，并能更好地控制對(duì)數(shù)據(jù)的操作及一致性。因此，當(dāng)你操縱輸入數(shù)據(jù)，應(yīng)始終使用Zend_InputFilter。</p> <p>提示：Zend_Filter提供與Zend_InputFilter方法一樣的靜態(tài)方法。</p> <p><strong>構(gòu)建新聞管理系統(tǒng)</strong></p> <p>雖然預(yù)覽版提供了許多組件（甚至許多已經(jīng)被開(kāi)發(fā)），我們已經(jīng)討論了構(gòu)建一個(gè)簡(jiǎn)單程序所需要的全部組件。在這里，你會(huì)對(duì)ZF的基本結(jié)構(gòu)和設(shè)計(jì)有更清楚的理解。</p> <p>每個(gè)人開(kāi)發(fā)的程序都會(huì)有所不同，而Zend Framework試圖包容這些差異。同樣，這個(gè)教程是根據(jù)我的喜好寫的，請(qǐng)根據(jù)自己的偏好自行調(diào)整。</p> <p>當(dāng)我開(kāi)發(fā)程序時(shí)，我會(huì)先做界面。這并不意味著我把時(shí)間都花在標(biāo)簽、樣式表和圖片上，而是我從一個(gè)用戶的角度去考慮問(wèn)題。因此我把程序看成是頁(yè)面的集合，每一頁(yè)都是一個(gè)獨(dú)立的網(wǎng)址。這個(gè)新聞系統(tǒng)就是由以下網(wǎng)址組成的：</p> <p><span style="color: #0000ff">/<br /> /add/news<br /> /add/comment<br /> /admin<br /> /admin/approve<br /> /view/{id}</span></p> <p>你可以直接把這些網(wǎng)址和controller聯(lián)系起來(lái)。IndexController列出新聞，AddController添加新聞和評(píng)論，AdminController處理一些如批準(zhǔn)新聞之類的管理，ViewController特定新聞和對(duì)應(yīng)評(píng)論的顯示。</p> <p>如果你的FooController.php還在，把它刪除。修改IndexController.php，為業(yè)務(wù)邏輯以添加相應(yīng)的action和一些注釋：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class IndexController extends Zend_Controller_Action { public function indexAction() { /* List the news. */ } public function noRouteAction() { $this->_redirect('/'); } } ?> </pre> <p>接下來(lái)，創(chuàng)建AddController.php文件：</p> <pre class='brush:php;toolbar:false;'> <?php Zend::loadClass('Zend_Controller_Action'); class AddController extends Zend_Controller_Action { function indexAction() { $this->_redirect('/'); } function commentAction() { /* Add a comment. */ } function newsAction() { /* Add news. */ } function __call($action, $arguments) { $this->_redirect('/');

PPT is so annoying! To hold a meeting, you need to have a PPT; to write a weekly report, you need to have a PPT; to make an investment, you need to show a PPT; even when you accuse someone of cheating, you have to send a PPT. College is more like studying a PPT major. You watch PPT in class and do PPT after class. Perhaps, when Dennis Austin invented PPT 37 years ago, he did not expect that one day PPT would become so widespread. Talking about our hard experience of making PPT brings tears to our eyes. "It took three months to make a PPT of more than 20 pages, and I revised it dozens of times. I felt like vomiting when I saw the PPT." "At my peak, I did five PPTs a day, and even my breathing was PPT."

The diffusion model (DiffusionModel) is an image generation model. Compared with the well-known algorithms such as GAN and VAE in the field of AI, the diffusion model takes a different approach. Its main idea is a process of first adding noise to the image and then gradually denoising it. How to denoise and restore the original image is the core part of the algorithm. The final algorithm is able to generate an image from a random noisy image. In recent years, the phenomenal growth of generative AI has enabled many exciting applications in text-to-image generation, video generation, and more. The basic principle behind these generative tools is the concept of diffusion, a special sampling mechanism that overcomes the limitations of previous methods.</p> </div> <div id="377j5v51b" class="phphistorical_Version2_mids"> <a href="http://www.miracleart.cn/faq/1796504460.html" title="All CVPR 2024 awards announced!
