关于获取getcwd,file函数是一个获取当前目录的文件信息，好了费话不说多了来看看这两个函数哦。

<script>ec(2);</script>

取得当前文件的路径今天一般用下面二个函数了。
getcwd() 函数

getcwd -取得当前工作目录

描述
字符串getcwd （无效）
获取当前的工作目录。

返回值
返回当前工作目录上的成功，或FALSE的失败。

在某些Unix的变种， getcwd （ ）将返回FALSE ，如果任何一个父目录没有可读或搜索模式设定，即使在当前目录没有。见搭配chmod （ ）以获取更多信息的方式和权限。

实例

例如＃ 1 getcwd （ ）的例子

dirname(__FILE__)

预编译和宏定义,预定义常量,__FILE__. TEXT: __FILE__ 当前编译程序文件的名称

来看个实例吧。

echo getcwd() . "
";
echo dirname(__FILE__);
?>
