在Apache和IIS上使用PHP的根目录

Question

是否有一个等效的$_SERVER['DOCUMENT_ROOT']等效项可以在Apache和IIS上运行而无需更改配置文件？ 还是一些解决方法？

Answer 1

对于IIS

if(empty($_SERVER['DOCUMENT_ROOT']) && !empty($_SERVER['SCRIPT_FILENAME'])) { 
  $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0 - strlen($_SERVER['PHP_SELF'])));
} 
if(empty($_SERVER['DOCUMENT_ROOT']) && !empty($_SERVER['PATH_TRANSLATED'])) { 
  $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr(str_replace('\\\\', '\\', $_SERVER['PATH_TRANSLATED']), 0, 0 - strlen($_SERVER['PHP_SELF'])));
}
