__FILE__ 与 $_SERVER['SCRIPT_FILENAME']的区别

 
阅读更多

二者都表明了本文件的绝对路径，区别在于，
$_SERVER['SCRIPT_FILENAME']指向当前执行脚本的绝对路径；
__FILE__指向当前文件的绝对路径；也就是写在哪个文件里就是哪里。

例子：

    

  1. //test.php
    2. 

  2. require'common/inc.php';
    3. 

    

  1. //common/inc.php
    2. 

  2. echo'SCRIPT_FILENAME为：'.$_SERVER['SCRIPT_FILENAME'];
    3. 

  3. echo'<br/>';
    4. 

  4. echo'__FILE__为：'.__FILE__;
    5.

执行test.php，显示结果为：

SCRIPT_FILENAME 为：D:/AppServ/www/test.php
__FILE__为：D:\AppServ\www\common\inc.php
