PHP的快速发展，它的功能越来越强大，运用它也变得很方便，下面我们就PHP5安装配置详细的介绍一下。PHP的执行效率是有目共睹的，这也是我喜欢它的原因之一，和它称为绝妙搭档的Mysql以及Apache想融合，不能不惊叹其效率了。
PHP安装配置
1.解压缩PHP压缩包到C:PHP（这个路径可以随意，不过以下要是用到这个路径，请相应的修改）。
2.复制C:PHP目录下的php4ts.dll及C:PHPdlls目录下的所有文件到windows的系统文件夹里，文件夹视Windows版本的不同而不同
◆如果是Windows 9x/ME则为c:windowssystem
◆如果是Windows NT/2000则为c:winntsystem32
◆如果是Windows XP/server2003则为c:windowssystem32
其中C:为你现在所使用的操作系统的系统盘，如果你目前操作系统不是安装在C:windows下，请相应做出修改。复制php.ini-dist到C:windows(XP/2003/9x/Me)或C:Winnt(2000/nt)下，并将其改名为php.ini。用记事本打开，修改一下信息：搜索extension_dir = ./ 这行，并将其路径指到你的PHP目录下的extensions目录，比如：
<ol class="dp-xml"><li class="alt"><span><span class="attribute"><font color="#ff0000">extension_dir</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">C</font></span><span>:PHPextensions </span></span></li></ol>
如若想支持更多模块，请接下面去做，如果不想的话，直接保存php.ini文件即可. PHP所支持模块很多，不过有些dll不是免费的，所以没有随PHP的压缩包一起发布，不过dlls文件夹里带的就非常多了，刚才我们已经把它们复制到 system32文件夹下了，现在我们测试看它支持多少模块。以下是我测试的结果，仅供参考，如果安装完毕后，弹出不支持xxx.dll模块的话，直接将前面分号加上去就可以了，搜索：
<ol class="dp-xml"> <li class="alt"><span><span>Windows Extensions </span></span></li> <li class=""><span>Note that MySQL and ODBC support is now built in, so no dll is needed for it. </span></li> </ol>
下面都用分号在前面注释掉了支持的扩展模块，如果你想PHP支持某个模块，请将前面的“;”去掉即可,下面是我测试后的结果,一般按照下面那样去掉注释后没什么问题的:
<ol class="dp-xml"> <li class="alt"><span><span class="attribute">extension</span><span>=</span><span class="attribute-value">php_bz2</span><span>.dll </span><span
