虽然__FILE__和$_SERVER是最好的方法，但在某些情况下，这也是一种替代方法:

get_included_files();

它包含调用它的文件路径和所有其他包含。

参见http://php.net/manual/en/function.pathinfo.php

pathinfo(__FILE__, PATHINFO_FILENAME);

试试这个

$file = basename($_SERVER['PATH_INFO'])

你也可以用这个:

echo $pageName = basename($_SERVER['SCRIPT_NAME']);

以下是我最近在寻找答案时发现的一个列表:

//self name with file extension
echo basename(__FILE__) . '<br>';
//self name without file extension
echo basename(__FILE__, '.php') . '<br>';
//self full url with file extension
echo __FILE__ . '<br>';

//parent file parent folder name
echo basename($_SERVER["REQUEST_URI"]) . '<br>';
//parent file parent folder name with //s
echo $_SERVER["REQUEST_URI"] . '<br>';

// parent file name without file extension
echo basename($_SERVER['PHP_SELF'], ".php") . '<br>';
// parent file name with file extension
echo basename($_SERVER['PHP_SELF']) . '<br>';
// parent file relative url with file etension
echo $_SERVER['PHP_SELF'] . '<br>';

// parent file name without file extension
echo basename($_SERVER["SCRIPT_FILENAME"], '.php') . '<br>';
// parent file name with file extension
echo basename($_SERVER["SCRIPT_FILENAME"]) . '<br>';
// parent file full url with file extension
echo $_SERVER["SCRIPT_FILENAME"] . '<br>';

//self name without file extension
echo pathinfo(__FILE__, PATHINFO_FILENAME) . '<br>';
//self file extension
echo pathinfo(__FILE__, PATHINFO_EXTENSION) . '<br>';

// parent file name with file extension
echo basename($_SERVER['SCRIPT_NAME']);

别忘了删除:)

更通用的方法是使用pathinfo()。从5.2版本开始，它支持PATHINFO_FILENAME。

So

pathinfo(__FILE__,PATHINFO_FILENAME)

也会做你需要的事。
