ThinkPHP3.2 加载过程（2）

ThinkPHP3.2 加载过程（二）

回顾：

　　上次介绍了 ThinkPHP 的 Index.PHP入口文件。但只是TP的入口前面的入口（刷boss总是要过好几关才能让你看到 ，不然boss都没面子啊），从Index.PHP最后一行把我们引路到了TP的大门前（ThinkPHP/ThinkPHP.php）

// 引入ThinkPHP入口文件require './ThinkPHP/ThinkPHP.php';

本次目标：

　　查看TP的大门，同时稍微探索一下大门内部的东西

正文：

　　先上代码

解释：

　　1 - 5 行：初始化 运行的时间 内存之类的东东，给开发人员提供代码运行效率直观上的体现

　　8 行：不猜也能知道 就是版本好的说明嘛

　　11-14行：定义4个数据嘛，也就是浏览器地址的解析模式（等一下解释）

　　17　 行：这里不是看到是不是感觉到 我们如果加一个php时候的文件的后缀

　 20-49行：定义各种变量 但是下面的这段代码 其中有一个函数 get_magic_quotes_gpc() 这个函数做什么用 我大致查选了一下 大致说法 参考。TP里面 能起到多大的作用 我也不是很清楚 如果谁知道 欢迎给大家说明一下

　　　　PHP解析器就会自动为post、get、cookie过来的数据增加转义字符“\”，以确保这些数据不会引起程序，特别是数据库语句因为特殊字符引起的污染而出现致命的错误。

<span style="color: #008080;">1</span> <span style="color: #0000ff;">if</span>(<span style="color: #008080;">version_compare</span>(<span style="color: #ff00ff;">PHP_VERSION</span>,'5.4.0','<'<span style="color: #000000;">)) {</span><span style="color: #008080;">2</span>     <span style="color: #008080;">ini_set</span>('magic_quotes_runtime',0<span style="color: #000000;">);</span><span style="color: #008080;">3</span>     <span style="color: #008080;">define</span>('MAGIC_QUOTES_GPC',<span style="color: #008080;">get_magic_quotes_gpc</span>()? <span style="color: #0000ff;">true</span> : <span style="color: #0000ff;">false</span><span style="color: #000000;">);</span><span style="color: #008080;">4</span> }<span style="color: #0000ff;">else</span><span style="color: #000000;">{</span><span style="color: #008080;">5</span>     <span style="color: #008080;">define</span>('MAGIC_QUOTES_GPC',<span style="color: #0000ff;">false</span><span style="color: #000000;">);</span><span style="color: #008080;">6</span> }

　　最后是加载核心Think类 和运行Think类中的start()这个方法

说明一下TP中的URL的几个模式 资料

普通模式下

1 const URL_COMMON = 0; //普通模式

　　 URL为 http://localhost/?m=home&c=user&a=login&var=value

m参数表示模块，c参数表示控制器，a参数表示操作（当然这些参数都是可以配置的），后面的表示其他GET参数。

　　'VAR_MODULE' => 'm', // 默认模块获取变量

　　'VAR_CONTROLLER' => 'c', // 默认控制器获取变量

　 'VAR_ACTION' => 'a', // 默认操作获取变量

　　值的定义在ThinkPHP\Conf\Convention.php

PATHINFO模式

1 const URL_PATHINFO = 1; //PATHINFO模式 该模式是默认模式

　　URL: http://localhost/index.php/home/user/login/var/value/

　　PATHINFO地址的前三个参数分别表示模块/控制器/操作。

　　说白了就是把普通模式下的几个M C A 变量给省掉 使用斜杠来代替

　　好处：1.看上去很整齐 2.据说可以提高被搜索引擎抓住的几率哦！！！

　　当然是斜杠还是别的是可以设置的在 ThinkPHP\Conf\Convention.php 文件中可以进行设置

　　 1 'URL_PATHINFO_DEPR' => '/', // PATHINFO模式下，各参数之间的分割符号

REWRITE模式

1 const URL_REWRITE = 2; //REWRITE模式

　　官方的原话 ： REWRITE模式是在PATHINFO模式的基础上添加了重写规则的支持，可以去掉URL地址里面的入口文件index.php，但是需要额外配置WEB服务器的重写规则。

　　如何是这样，那么我觉得应该就是 浏览器地址给重写以后在按照PATHINFO模式进行解析路由

兼容模式

1 const URL_COMPAT = 3; // 兼容模式

　　URL http://localhost/?s=/home/user/login/var/value

　　看到这个地址 YII的人有木有感觉很熟悉

　　为什么是S开头呢？是因为配置文件的设置 在 ThinkPHP\Conf\Convention.php

　　 1 'VAR_PATHINFO' => 's', // 兼容模式PATHINFO获取变量例如 ?s=/module/action/id/1 后面的参数取决于URL_PATHINFO_DEPR

修改模式方法

　　在配置文件 ThinkPHP\Conf\Convention.php

　　 1 'URL_MODEL' => 1, // URL访问模式,可选参数0、1、2、3,代表以下四种模式： 2 // 0 (普通模式); 1 (PATHINFO 模式); 2 (REWRITE 模式); 3 (兼容模式) 默认为PATHINFO 模式

对于以上集中模式个人的小总结：　　

　　不管是那个 我们把URL中出了模块名称开始前都去掉，就是不同的几种取出模块、控制器、控制器其中的方法名。所以在不配置路由和不使用默认的情况下，我们都能看到这三个参数。

总结：

　　ThinkPHP\ThinkPHP.php文件中 最主要的目的还是定义好各种目录的变量方便以后的调用

　　如果你发现代码中有一个定义你不知道做什么，如果是_path结尾（关于目录的），就去ThinkPHP\ThinkPHP.php中找找，别的那么就去ThinkPHP\Conf\Convention.php下找找 基本都能找到

几个思考（个人在整理时候想到的）：

　　1.定义IS_CGI ，IS_WIN，IS_CLI，MAGIC_QUOTES_GPC干嘛用

<span style="color: #008080;"> 1</span> <span style="color: #008000;">//</span><span style="color: #008000;"> 系统信息</span><span style="color: #008080;"> 2</span> <span style="color: #0000ff;">if</span>(<span style="color: #008080;">version_compare</span>(<span style="color: #ff00ff;">PHP_VERSION</span>,'5.4.0','<'<span style="color: #000000;">)) {</span><span style="color: #008080;"> 3</span>     <span style="color: #008080;">ini_set</span>('magic_quotes_runtime',0<span style="color: #000000;">);</span><span style="color: #008080;"> 4</span>     <span style="color: #008080;">define</span>('MAGIC_QUOTES_GPC',<span style="color: #008080;">get_magic_quotes_gpc</span>()? <span style="color: #0000ff;">true</span> : <span style="color: #0000ff;">false</span><span style="color: #000000;">);</span><span style="color: #008080;"> 5</span> }<span style="color: #0000ff;">else</span><span style="color: #000000;">{</span><span style="color: #008080;"> 6</span>     <span style="color: #008080;">define</span>('MAGIC_QUOTES_GPC',<span style="color: #0000ff;">false</span><span style="color: #000000;">);</span><span style="color: #008080;"> 7</span> <span style="color: #000000;">}</span><span style="color: #008080;"> 8</span> <span style="color: #008080;">define</span>('IS_CGI',(0 === <span style="color: #008080;">strpos</span>(PHP_SAPI,'cgi') || <span style="color: #0000ff;">false</span> !== <span style="color: #008080;">strpos</span>(PHP_SAPI,'fcgi')) ? 1 : 0<span style="color: #000000;"> );</span><span style="color: #008080;"> 9</span> <span style="color: #008080;">define</span>('IS_WIN',<span style="color: #008080;">strstr</span>(<span style="color: #ff00ff;">PHP_OS</span>, 'WIN') ? 1 : 0<span style="color: #000000;"> );</span><span style="color: #008080;">10</span> <span style="color: #008080;">define</span>('IS_CLI',PHP_SAPI=='cli'? 1   :   0);

　　2.为什么我们刚下载的架构不需要输入模块、控制器、方法名也能正常跳出页面。

 

好了，下一次我们就拿上小米加步枪杀进TP大门
