iis 下php多个版本共存问题

[gogo198]

在网上查了好多资料说的都不是很清楚，参考http://www.jz123.cn/text/1522864.html

主要是这里的php.ini的存放地址多的不是很清楚，他说放在windows/下面，放两个不就覆盖了。。。。还请知道的说下具体的配置，主要是在iis下

php.ini是随Web服务器启动时载入的，php.ini搜索位置如下：
==============================================================
http://www.php.net/manual/en/configuration.file.php

php.ini is searched in these locations (in order):

■SAPI module specific location (PHPIniDir directive in Apache 2, -c command line option in CGI and CLI, php_ini parameter in NSAPI, PHP_INI_PATH environment variable in THTTPD)

■The PHPRC environment variable. Before PHP 5.2.0 this was checked after the registry key mentioned below.

■As of PHP 5.2.0, the location of the php.ini file can be set for different versions of PHP. The following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x], where x, y and z mean the PHP major, minor and release versions. If there is a value for IniFilePath in these keys, then the first one found will be used as the location of the php.ini (Windows only).

■[HKEY_LOCAL_MACHINE\SOFTWARE\PHP], value of IniFilePath (Windows only).

■Current working directory (except CLI)

■The web server's directory (for SAPI modules), or directory of PHP (otherwise in Windows)

■Windows directory (C:\windows or C:\winnt) (for Windows), or --with-config-file-path compile time option

在IIS下面应该只能载入一个php.ini

当然，你可以使用Apache作为另一个Web服务器载入不同的php.ini

服务器东西杂，所以Apache不考虑，我也清楚Apache比iis好弄

微软发布 PHP Manager for IIS 7 ，这个是前几天看的新闻。

　　再也不用为在IIS上配置PHP而烦恼了，微软刚刚发布了面向IIS的PHP管理器版本1.0，x86和x64系统均可使用，用途如下：

　　*关联PHP和IIS

　　*并列运行多个PHP版本在同一台服务器上,甚至在同一网站

　　*检查PHP运行时配置和环境(的phpinfo()函数的输出)

　　*配置各种PHP设置

　　*启用或禁用PHP扩展

　　*远程管理php.ini PHP配置文件
