解决PHP相对目录问题

用include或requice包含文件时，文件路径前都加上dirname(__file__)。例如：现有a.php、b.php、c.php、d.php4个文件，他们关系为：

    b.php(与根目录同一级)
    根目录/a.php
    根目录/c.php
    根目录/dir/d.php

现在a.php中要包含b.php、c.php。写法如下：

include_once(dirname(__file__)."/../b.php");
include_once(dirname(__file__)."/c.php");
?>

如果c.php中要包含d.php。写法如下：

include_once(dirname(__file__)."/dir/d.php");
?>

此方式在目前来说是解决路径错位最有效的方法
