In this class, the teacher led us to create TEMPLATE. According to the teacher's teaching, we hope to write the code in this way: 1. For example, I define a variable $name=‘’; 2. Then I read a template. 3. Then I set some of my own "display formats" (hard style) in this template. 4. After loading the template, you can directly replace it with the above variables.

1. First create a new index.tpl in the template folder. The content is written like this

<?php echo &#39;<?php&#39; ?>  
/**
* project name: <?php echo $prj_name ?>  //大家想想， 它能運行嗎?
*User: <?php echo $prj_author ?>    //能運行嗎?
*Date: <?php echo date(&#39;Y-m-d&#39;)?>  //能嗎?
*/

    echo "hello shenyi";
?>

Okay, the preparations are done, we reference it in the god_frame class:

<?php
namespace core\frame;

class god_frame
{
    public  $project_folder = &#39;&#39;;       //項目文件夾
    public  $project_main = &#39;&#39;;         //入口文件
    function __construct($prjName){      //構(gòu)造函數(shù)
       $this->project_folder = getcwd()."/".$prjName;
       $this->project_main = $this ->  project_folder."/index.php";
    }
    function run(){

        //判斷并生成新的文件夾,沒有就創(chuàng)建
        !file_exists($this->project_folder) && mkdir($this->project_folder);
　　　　　//獲取外部成員變量并把該函數(shù)獲取的數(shù)組返回成變量列表　
        extract(get_object_vars($this));
        開啟PHP的內(nèi)部緩沖區(qū)（內(nèi)存）
        ob_start();
        //引入模板路徑
        include (dirname(__FILE__).&#39;/template/index.tpl&#39;);
        //獲取緩沖區(qū)的內(nèi)容,并賦給$cnt
        $cnt =ob_get_contents();
        //清理緩沖區(qū)內(nèi)容
        ob_end_clean();

        //在該文件夾下生成一個index.php文件,沒有就創(chuàng)建并覆蓋
        file_put_contents($this->project_main,"$cnt");
    }   
}
?>

I also need to improve the start (method) in godinit

static function start(){
        $get_config = loadConfig();
        $gf = new god_frame($get_config->prj_name);
        $gf -> prj_name = $get_config->prj_name;
        $gf -> prj_author = $get_config->prj_author;
        $gf -> run();
    }

Execute this method in the command line

Then let’s take a look at the directory structure of the entire document and the contents of index.php

Added knowledge points:

__FILE__:

dirname():

ob_start(): Start PHP internal buffer (memory). Put the content to be displayed next into the buffer first, and display it without haste.
ob_get_contents(); function to get the contents of the buffer
ob_end_clean(); You can clear the buffer contents, so that Output content
ob_end_flush(); Close the buffer and output the content
get_object_vars(); You can get the attribute variable values ????in the class (the instantiated class) and return the array.

extract();
