Homephp教程php手册php $_SERVER["REQUEST_URI"]获取值的通用解决方法

在 PHP 众多预定义服务器变量中,$_SERVER[REQUEST_URI] 算是经常用到的,但是这个变量只有 apache 才支持,因此,我们需要一个更加通用的方式来获取 REQUEST_URI 的值,本文就是结束这一问题的解决方案。

代码如下:
// 说明:获取 _SERVER['REQUEST_URI'] 值的通用解决方案
function request_uri()
{
if (isset($_SERVER['REQUEST_URI']))
{
$uri = $_SERVER['REQUEST_URI'];
}
else
{
if (isset($_SERVER['argv']))
{
$uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0];
}
else
{
$uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING'];
}
}
return $uri;
}
?>
