<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">PHP底层工作原理</strong></p><img src="https://mmbiz.qpic.cn/mmbiz_png/LFP9SpGv0PEF9H5m9ZUVsFVqa42LwNQfX9iavbk9y8IjUiaT3ia6STSbIob7iaKLicj8mPyXkMQQNX1lbvycfiabBQCQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">图1 php结构</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从图上<span style="color: black;">能够</span>看出，php从下到上是一个4层体系</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">①Zend引擎</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Zend整体用纯c实现，是php的内核部分，它将php代码翻译(词法、语法解析等一系列编译过程)为可执行opcode的处理并实现相应的处理<span style="color: black;">办法</span>、实现了基本的数据结构(如hashtable、oo)、内存分配及管理、<span style="color: black;">供给</span>了相应的api<span style="color: black;">办法</span>供<span style="color: black;">外边</span>调用，是一切的核心，所有的外围功能均围绕zend实现。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">②Extensions</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">围绕着zend引擎，extensions<span style="color: black;">经过</span>组件式的方式<span style="color: black;">供给</span><span style="color: black;">各样</span><span style="color: black;">基本</span>服务，<span style="color: black;">咱们</span><span style="color: black;">平常</span>的<span style="color: black;">各样</span>内置函数(如array系列)、标准库等都是<span style="color: black;">经过</span>extension来实现，用户<span style="color: black;">亦</span><span style="color: black;">能够</span><span style="color: black;">按照</span>需要实现自己的extension以达到功能扩展、性能优化等目的(如贴吧正在<span style="color: black;">运用</span>的php中间层、富文本解析<span style="color: black;">便是</span>extension的典型应用)。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">③Sapi</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Sapi全<span style="color: black;">叫作</span>是Server Application Programming Interface，<span style="color: black;">亦</span><span style="color: black;">便是</span>服务端应用编程接口，sapi<span style="color: black;">经过</span>一系列钩子函数，使得php<span style="color: black;">能够</span>和外围交互数据，这是php非常优雅和成功的一个设计，<span style="color: black;">经过</span>sapi成功的将php本身和上层应用解耦隔离，php<span style="color: black;">能够</span><span style="color: black;">再也不</span><span style="color: black;">思虑</span><span style="color: black;">怎样</span>针对<span style="color: black;">区别</span>应用进行兼容，而应用本身<span style="color: black;">亦</span><span style="color: black;">能够</span>针对自己的特点实现<span style="color: black;">区别</span>的处理方式。后面将在sapi章节<span style="color: black;">中间商</span>绍</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">④上层应用</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这<span style="color: black;">便是</span><span style="color: black;">咱们</span>平时编写的php程序，<span style="color: black;">经过</span><span style="color: black;">区别</span>的sapi方式得到<span style="color: black;">各样</span>各样的应用模式，如<span style="color: black;">经过</span>webserver实现web应用、在命令行下以脚本方式运行等等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">构架思想：</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">引擎(Zend)+组件(ext)的模式降低内部耦合</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">中间层(sapi)隔绝web server和php</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">**************************************************************************</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">倘若</span>php是一辆车，<span style="color: black;">那样</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车的框架<span style="color: black;">便是</span>php本身</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Zend是车的引擎(发动机)</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Ext下面的<span style="color: black;">各样</span>组件<span style="color: black;">便是</span>车的轮子</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Sapi<span style="color: black;">能够</span>看做是公路，车<span style="color: black;">能够</span>跑在<span style="color: black;">区别</span>类型的公路上</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而一次php程序的执行<span style="color: black;">便是</span>汽车跑在公路上。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此呢</span>，<span style="color: black;">咱们</span>需要：性能优异的引擎+合适的车轮+正确的跑道</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache和php的关系</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache<span style="color: black;">针对</span>php的解析，<span style="color: black;">便是</span><span style="color: black;">经过</span>众多Module中的php Module来完成的。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/LFP9SpGv0PEF9H5m9ZUVsFVqa42LwNQfC40p84vykda7oDgFUBJtdCLdAuPv9hicB7sObWjicMHcTUH0jU59JXbg/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">把php<span style="color: black;">最后</span>集成到Apache系统中，还需要对Apache进行<span style="color: black;">有些</span>必要的设置。<span style="color: black;">这儿</span>，<span style="color: black;">咱们</span>就以php的mod_php5 SAPI运行模式为例进行讲解，至于SAPI这个概念后面<span style="color: black;">咱们</span>还会<span style="color: black;">仔细</span>讲解。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">假定<span style="color: black;">咱们</span>安装的版本是Apache2 和 Php5，<span style="color: black;">那样</span>需要编辑Apache的主配置文件http.conf，在其中加入下面的几行内容：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">Unix/Linux环境下：</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">LoadModule php5_module modules/mod_php5.so</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">AddType application/x-httpd-php .php</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">注：其中modules/mod_php5.so 是X系统环境下mod_php5.so文件的安装位置。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">Windows环境下：</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">LoadModule php5_module d:/php/php5apache2.dll</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">AddType application/x-httpd-php .php</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">注：其中d:/php/php5apache2.dll 是在Windows环境下php5apache2.dll文件的安装位置。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这两项配置<span style="color: black;">便是</span>告诉Apache Server，以后收到的Url用户请求，凡是以php<span style="color: black;">做为</span>后缀，就需要调用php5_module模块(mod_php5.so/ php5apache2.dll)进行处理。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、Post-Read-Request<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在正常请求处理流程中，这是模块<span style="color: black;">能够</span><span style="color: black;">插进</span>钩子的<span style="color: black;">第1</span>个<span style="color: black;">周期</span>。<span style="color: black;">针对</span><span style="color: black;">哪些</span>想很早进入处理请求的模块<span style="color: black;">来讲</span>，这个<span style="color: black;">周期</span><span style="color: black;">能够</span>被利用。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、URI Translation<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：将请求的URL映射到本地文件系统。模块<span style="color: black;">能够</span>在这<span style="color: black;">周期</span><span style="color: black;">插进</span>钩子，执行自己的映射<span style="color: black;">规律</span>。mod_alias<span style="color: black;">便是</span>利用这个<span style="color: black;">周期</span>工作的。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4、Access Control<span style="color: black;">周期</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：<span style="color: black;">根据</span>配置文件设定的策略对用户进行认证，并设定用户名区域。模块<span style="color: black;">能够</span>在这<span style="color: black;">周期</span><span style="color: black;">插进</span>钩子，实现一个认证<span style="color: black;">办法</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">6、Authorization<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：<span style="color: black;">按照</span>配置文件<span style="color: black;">检测</span><span style="color: black;">是不是</span><span style="color: black;">准许</span>认证过的用户执行请求的操作。模块<span style="color: black;">能够</span>在这<span style="color: black;">周期</span><span style="color: black;">插进</span>钩子，实现一个用户权限管理的<span style="color: black;">办法</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">7、MIME Type Checking<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：<span style="color: black;">按照</span>请求资源的MIME类型的<span style="color: black;">关联</span>规则，判定将要<span style="color: black;">运用</span>的内容处理函数。标准模块mod_negotiation和mod_mime实现了这个钩子。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">8、FixUp<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这是一个通用的<span style="color: black;">周期</span>，<span style="color: black;">准许</span>模块在内容生成器之前，运行任何必要的处理流程。和Post_Read_Request类似，这是一个能够<span style="color: black;">捕捉</span>任何信息的钩子，<span style="color: black;">亦</span>是最常<span style="color: black;">运用</span>的钩子。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">9、Response<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：生成返回客户端的内容，负责给客户端发送一个恰当的回复。这个<span style="color: black;">周期</span>是<span style="color: black;">全部</span>处理流程的核心部分。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">十、</span>Logging<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：在回复<span style="color: black;">已然</span>发送给客户端之后记录事务。模块可能修改<span style="color: black;">或</span>替换Apache的标准日志记录。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">11、CleanUp<span style="color: black;">周期</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Apache在本<span style="color: black;">周期</span>的<span style="color: black;">重点</span>工作：清理<span style="color: black;">这次</span>请求事务处理完成之后遗留的环境，<span style="color: black;">例如</span>文件、目录的处理<span style="color: black;">或</span>Socket的关闭等等，这是Apache一次请求处理的最后一个<span style="color: black;">周期</span>。</p>
