php warning: php startup: in unknown on line 0

Windows下运行php-cgi报错如下：

D:\php>php-cgi.exe -b 127.0.0.1:9000 -c php.ini

PHP Warning:  PHP Startup:  in Unknown on line 0

Warning:  PHP Startup:  in Unknown on line 0

PHP Warning:  PHP Startup:  in Unknown on line 0

Warning:  PHP Startup:  in Unknown on line 0

PHP Warning:  PHP Startup:  in Unknown on line 0

解决方法：

这是PHP配置的问题，找开php.ini文件，找到“extension_dir”

;extension_dir = "./"  改为：extension_dir = "D:/php/ext"

注：更改为绝对路径即可；
