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
<br />
<b>Warning</b>: PHP Startup: in <b>Unknown</b> on line <b>0</b><br />
PHP Warning: PHP Startup: in Unknown on line 0
<br />
<b>Warning</b>: PHP Startup: in <b>Unknown</b> on line <b>0</b><br />
PHP Warning: PHP Startup: in Unknown on line 0
<br />
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；
