Wamp升级PHP版本

方法一：

1.  停止WAMP服务器.

2.  去网站windows.php.net 下载PHP 5.4 VC9 x86 Non Thread Safe

不要下载THE INSTALLER.

3.  在wamp/bin/php创建php5.4.45文件夹 

4.  把下载的zip包解压到php5.4.45文件夹中

5.  从已存在的php版本文件中（如php5.4.45， (eg.   wamp/bin/php/php5.3.3)）复制以下文件: -  php.ini、phpForApache.ini和wampserver.conf到php5.4.45文件夹.

6.  打开php5.4.45文件夹的以下文件: -   php.ini和phpForApache.ini并且把5.2.5替换为5.4.45。

7.  去wamp/bin/apache/apache/apache2.2.11/bin删除php.ini文件。将5.2.5文件夹中的php5apache2_2.dll和php5apache2_2_filter.dll复制到php5.4.45中去(我就漏了这步导致无法启动)

修改Wamp配置文件：进入 Wamp的安装目录，用IDE或记事本（最好使用行号定位的记事本，如EditPlus等）打开 wampmanager.ini，定位到 335 行，通常在这一行就是[phpVersion]，如果不是，则在附近找找。复制下面一行：

Type: item; Caption: "5.3.0"; Action: multi; Actions:switchPhp5.3.0
插入到这一行前面，并修改为

Type: item; Caption: "5.2.17"; Action: multi; Actions:switchPhp5.2.17

再复制

[switchPhp5.3.0]
Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated
Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "switchPhpVersion.php 5.3.0";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
Action: resetservices
Action: readconfig;

插入这一段之前，并修改为

[switchPhp5.2.17]
Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated

Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "switchPhpVersion.php 5.2.17";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated

Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
Action: resetservices
Action: readconfig;

8.重启wamp.

9. 选择旧版本5.2.5

10. 选择后会重启wamp。

11. 此时就可以选择php->version-> 5.4.45 .

12. 重启成功.完成

必须要下载VC9处理器

方法二：

安装成功：先安装wampServer2.0，拷贝php5.2.5 出来，卸载，在安装wampserver2.1，版本php5.3.3

WampServer的Version菜单（Apache、PHP、Mysql各自有一个Version菜单）上，有一个 Get More... 连接，点击它就可以到官网上下载你需要的版本，安装是自动化的，非常简单。但是，到我写本文为止，官网的PHP5.2最高为5.2.11，PHP5.3最高为5.3.1。5.2最稳定的5.2.17、5.3最新的5.3.8都没有提供，而且更新非常慢。没有我们需要的版本，怎么办？毛大爷说过一句至理名言：自己动手，丰衣足食！

手工安装新版本的PHP，只需以下步骤：

1. 下载要安装的PHP版本。既然是用WampServer，那当然是下载Window版本的ZIP包啦：http://windows.php.net。解压到 Wamp的安装目录inphpphp5.2.17。这里以5.2.17为例。
2. 进入 Wamp的安装目录inphpphp5.2.17 目录，从 php.ini-dist 或者 php.ini-recommended 复制一份，重命名为php.ini，适应修改php.ini配置（如extension_dir），再从php.ini复制一分，重命名为 phpForApache.ini。
3. 从已有的版本目录中复制一份 wampserver.conf。比如我安装WampServer的时候已经有php5.3.0，在 Wamp的安装目录inphpphp5.3.0 目录下复制 wampserver.conf 到 Wamp的安装目录inphpphp5.2.17。
4. 修改Wamp配置文件：进入 Wamp的安装目录，用IDE或记事本（最好使用行号定位的记事本，如EditPlus等）打开 wampmanager.ini，定位到 335 行，通常在这一行就是[phpVersion]，如果不是，则在附近找找。复制下面一行：
   Type: item; Caption: "5.3.0"; Action: multi; Actions:switchPhp5.3.0
   插入到这一行前面，并修改为

   Type: item; Caption: "5.2.17"; Action: multi; Actions:switchPhp5.2.17

   再复制
   [switchPhp5.3.0]
   Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated
   Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "switchPhpVersion.php 5.3.0";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
   Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
   Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
   Action: resetservices
   Action: readconfig;
   插入这一段之前，并修改为
   
   [switchPhp5.2.17]
   Action: service; Service: wampapache; ServiceAction: stop; Flags: ignoreerrors waituntilterminated
   

   Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "switchPhpVersion.php 5.2.17";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated
   Action: run; FileName: "Wamp的安装目录/bin/php/php5.3.0/php-win.exe";Parameters: "-c . refresh.php";WorkingDir: "Wamp的安装目录/scripts"; Flags: waituntilterminated

   Action: run; FileName: "net"; Parameters: "start wampapache"; ShowCmd: hidden; Flags: waituntilterminated
   Action: resetservices
   Action: readconfig;
5. 退出WampServer，再重启。完成。

通过这5步，即可完成PHP任意版本的安装。

另附两个文件的实例：

1. Wamp的安装目录inphpphp5.2.17wampserver.conf，这实际是PHP文件

<?php

$phpConf['phpIniDir'] = '.';
$phpConf['phpExeDir'] = '.';
$phpConf['phpConfFile'] = 'php.ini';


$phpConf['apache']['1.3']['LoadModuleName'] = 'php5_module';
$phpConf['apache']['1.3']['LoadModuleFile'] = 'php5apache.dll';
$phpConf['apache']['1.3']['AddModule'] =  'mod_php5.c';

$phpConf['apache']['2.0']['LoadModuleName'] = 'php5_module';
$phpConf['apache']['2.0']['LoadModuleFile'] = 'php5apache2.dll';
$phpConf['apache']['2.0']['AddModule'] =  '';

$phpConf['apache']['2.2']['LoadModuleName'] = 'php5_module';
$phpConf['apache']['2.2']['LoadModuleFile'] = 'php5apache2_2.dll';
$phpConf['apache']['2.2']['AddModule'] =  '';

?>

2. Wamp的安装目录wampmanager.ini 

[phpVersion]

;WAMPPHPVERSIONEND 

如果要复制以上文件，注意更改版本号与路径。
