PHP预定义常量__FILE__

    目录结构:

    --F:\website\webgis\index.php


  测试代码:index.php

echo "<br>测试输出__FILE__";echo "<br>".__FILE__;echo "<br>".dirname(__FILE__);

  输出结果:

测试输出__FILE__
F:\website\webgis\index.php
F:\website\webgis

  

  总结:__FILE__输出当前文件的路径。include(index.php)情况下,输出的路径也是F:\website\webgis\index.php。
