PHP不僅僅是PHP,PHPPHP
PHP不僅僅是PHP。
PHP的面試不僅僅會問到PHP語言本身(基本都是基礎(chǔ)和細節(jié)),下面列舉的主要是都是高級工程師的要求
比如:PHP中include和require的區(qū)別詳解,
各個版本間差異,就算沒用過別的版本,也要看一下私下學習一下,也至少要看一下版本7,體現(xiàn)你的愛學習有學習精神(會有加分哦)
然后還會問到:
MySQL:包括索引(索引命中),引擎(常用引擎及區(qū)別),高并發(fā),表結(jié)構(gòu)的設計,如何排查慢查詢
HTTP協(xié)議:三次握手,狀態(tài)碼,請求的頭部和body以及響應的各個關(guān)鍵字的說明,長連接短連接等
服務器(Linux系統(tǒng)):shell編程,命令(權(quán)限,IO等監(jiān)控),如何排查系統(tǒng)瓶頸,高并發(fā)
web容器:Nginx和Apache的區(qū)別,高并發(fā),一個PHP請求發(fā)起到頁面展示給用戶中間發(fā)生了什么。。。
C語言:畢竟PHP是C開發(fā),源碼是C,深入后需要懂得C,高效的框架都是C寫的(比如yaf),擴展
算法:冒泡排序,快速排序等,還有一些其他的,比如(30瓶水,其中一瓶有毒,使用小白鼠來實驗找出有毒的水,小白水喝水后2個小時死亡,請問至少需要多少只小白鼠才能找到那瓶水,請描述),還有我的面試題之算法集錦,還有一題(有n個臺階,每次走1-m步,請問走到頭一共有多少種走法,m≤n)
架構(gòu):360面試題(設計一個短鏈接系統(tǒng),可以支持10億的訪問量),百度面試題(設計一個投票系統(tǒng),如何做到高并發(fā)和防止重復投等)--親身參與過(多么痛的領(lǐng)悟)
框架:yaf,yii,thinkphp等(選擇了解)
前端:html(含h5),css(含css3),js(包括原生和jquery以及其他的庫)
面向?qū)ο螅憾鄳B(tài),繼承,封裝,抽象
緩存服務器:redis和memcache的區(qū)別和內(nèi)部實現(xiàn)原理,memcache和memcached的區(qū)別
其實進入某個大公司上面很多東西用不著,或者已經(jīng)有現(xiàn)成的方案,不需要你去操心,但是咱們要有打破砂鍋問到底的精神,要搞懂它不能繞過它。
所以功夫下在平時不要到要開始面試找工作了才去看才去學,已經(jīng)晚了(多么痛的領(lǐng)悟)
上面的東西我是想到那寫到哪。。。沒有前后順序,沒有側(cè)重點,任何一個方面面試官都會問到
面試也要是看運氣的,但是不能全憑運氣
Good luck.

jsp belongs to the backend. The essence of jsp is a servlet, and servlet is a server-side java application, so jsp is a back-end technology. JSP is deployed on the web server and can respond to requests sent by the client and dynamically generate web pages of HTML, XML or other format documents based on the request content, and then return them to the requester. JSP technology uses Java as a scripting language to provide services for user HTTP requests, and can handle complex business requirements together with other Java programs on the server.

Implementation steps: 1. Introduce the JSTL tag library into the JSP page; 2. Obtain data from the database; 3. Paging the data; 4. Display the paging navigation bar in the page; 5. Display the number according to the current page number and each page. , just get the corresponding data from the paging data and display it on the page.

The difference between jsp and html: 1. Operating mechanism; 2. Purpose; 3. Relationship with Java; 4. Function; 5. Relationship with back-end; 6. Speed; 7. Maintainability and scalability; 8. Learning and use Difficulty; 9. File suffixes and identification tools; 10. Community and support; 11. Security. Detailed introduction: 1. Operating mechanism. HTML is a markup language, mainly used to describe and define the content of web pages. It runs on the client and is interpreted and executed by the browser. JSP is a dynamic web page technology that runs on the server side, etc. wait.

Can JSP be replaced by PHP? JSP (JavaServerPages) and PHP (HypertextPreprocessor) are commonly used server-side scripting languages ??for dynamically generating web page content. Although they each have their own characteristics and advantages, can they completely replace each other in practical applications? This article will analyze the advantages and disadvantages of the two and compare them through specific code examples. First, let's take a look at the respective characteristics of JSP and PHP. JSP is a Java-based

?JSP is a dynamic web technology standard. Its file format is to insert Java program segments (Scriptlet) and JSP tags (tags) into traditional web page HTML files (.htm, .html) to form JSP files (*.jsp ).

1. The core sql statement to implement paging query (1) The sql statement to query the total number of records in the database: selectcount(*)from+(table name); (2) The sql statement to query the number of records for each query: where: 0 is searched Index, 2 is the number of items searched each time. select*from table name limit0,2; 2. Code implementation* I wrote these two classes in the previous article, DBconnection class: used to obtain database connections, Author object class. Click on the link to view the code for these two classes. Click the link to view the DBconnection class and Author object class (1) Login page: index.jsp. Inserttitlehere user column

After the new springboot project is created, the directory is as follows: Step 1: Add the jar package code required to configure jsp to the project's pom file: org.apache.tomcat.embedtomcat-embed-jasperprovided Step 2: Create a new directory webapp under the main path , create a new path WEB-INF under webapp, create a new path jsp under WEB-INF, and place the jsp file we want to use under this path. Step 3: Configure the access path and suffix code of the jsp file in the main configuration file: spring .mvc.view.prefix=/WEB-INF/jsp/sp

Can PHP replace the functionality of JSP? As web development technology continues to evolve, developers are often faced with choosing the appropriate server-side language to implement their project needs. In this regard, PHP and JSP are two common choices. JSP is the abbreviation of JavaServerPages, which is a server-side technology based on Java, while PHP is a server-side scripting language. This article will explore whether PHP can replace the functions of JSP and provide some specific code examples to help readers better understand
