PHP学习启动,环境大搭建

PHP学习起步,环境大搭建

本文章教你如何一步一步搭起PHP开发环境

虽然在网上可以随便找到相关的PHP搭建环境，可是我觉得有几点不好，搭建的方式不一，使得开发者不知道相信谁的话，其二，对于开发者在搭建的过程中遇到的问题避而不答，我觉得这是最要命的。其三，搭配的版本不一，其涉及的搭配核心没有告诉开发者，于下，我将避重就轻，介绍PHP环境的搭建和测试。

• 下载好所需的软件，由于我比较倾向较新的版本，所以我的搭建环境是Win 7+PHP5.2.17+MySql5.5.23+Apache2.2.22
• 这里要注意的一点就是PHP,下载时候尽量选择压缩包格式，一方面压缩包说占用的空间较少，最重要的是如果使用安装包的话，那么安装之后你会发现安装目录中会缺少很多文件，不如拓展文件，这个问题让我很恼火，我重装了2次，问题还是依旧，所以我就断定安装包的问题，所以最好的处理方式就是使用压缩包，这里我选择的是VC6 x86 Thread Safe (2011-Mar-22 13:29:30)下载地址是：http://windows.php.net/downloads/releases/php-5.2.17-Win32-VC6-x86.zip这里没选择VC9是因为，给版本针对IIS（官网是这样说的）。
• 至于软件的安装，我在这就不造轮子了，不同的版本大同都有些差异，比如MySql，由于我安装的是最新版的，其安装的变化之大，只有自己慢慢领悟，还有一点就是安装Apache时需要你填domain，这个不太重要，但是要填正确，我填的是本地的地址127.0.0.1（或者localhost）.还有注意一点的是，安装目录最好自定义，不建议安装在Program Files文件中，安装的步骤自己安装说明来基本没什么大问题。
• 软件的关联，这里需要关联的是，将PHP关联到Apache服务器上，将PHP关联的MySql数据库上

1. 将PHP关联到Apache服务器上和数据库上，需要修改以下的配置文件，在Apache目录下的/conf/httpd.conf文件的末尾被PHP安装程序加增加了几句配置：httpd.conf

   然后需要打开PHP的MYSQL功能，将如下行的注释（以分号;开头的行）去掉，并将其余暂时用不到externsion用注释(;)关闭掉。

   php.ini

   1 2 3 4 5 6 7 8

   extension=php_curl.dll extension=php_gd2.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_pdo.dll extension=php_pdo_mysql.dll extension=php_pdo_odbc.dll extension=php_xmlrpc.dll

   配置完成，重启Apache服务器，如果没什么意外的话，这样的配置是不会出错的。
