配置php4或者php5的过程中,php4,5的配置的步骤大致一样的,但是配置内容有一些差别。在LINUX等环境下编译,一般来说,只要编译的选项正确,配置也就正确了;在windows配置则需要注意以下不同点:
1. php4ts.dll 和 php5ts.dll
这个文件要拷贝到apache的bin目录下或者系统目录下
2. httpd.conf 文件加载的模块
示例如下:
# For PHP4 + apache1.x.xx
LoadModule php4_module d:/www/webserver/php4/sapi/php4apache.dll
AddType application/x-httpd-php .php

# For PHP4 + apache2.x.xx
LoadModule php4_module d:/www/webserver/php4/sapi/php4apache2.dll
AddType application/x-httpd-php .php

# 其中d:/www/webserver/php4是php的所在目录。

# For PHP5 + apache1.x.xx
LoadModule php5_module d:/www/webserver/php5/php5apache.dll
AddType application/x-httpd-php .php

# For PHP5 + apache2.x.xx
LoadModule php5_module d:/www/webserver/php5/php5apache2.dll
AddType application/x-httpd-php .php

# 其中d:/www/webserver/php5是php的所在目录。

3. 加载mysql的方式不同

在php4以及以前的版本中,mysql是集成在php中的;
而在PHP5(包括BETA)版本,mysql是作为一个模块加载的,需要设置php.ini来加载,例如
extension_dir = "D:/www/WebServer/PHP5/ext/"
extension=php_mysql.dll

另外,PHP4,PHP5都需要系统目录下的libmysql.dll的支持,如果版本不对,即使你设置了正确的extension_dir和php_mysql.dll的参数,也会造成apache启动的时候提示phpp_mysql.dll找不到的错误。
