西安网络公司,HOOBOO使用PHP编写程序的时候,我们常常想要获取当前页面的URL。下面提供一个用于获取当前页面URL的函数以及使用方法:
实例一:
function get_full_url(){
$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
$url = $protocol.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
return $url;
}
详解
//获取域名或主机地址
echo $_SERVER['HTTP_HOST']."<br>"; #localhost
//获取网页地址
echo $_SERVER['PHP_SELF']."<br>"; #/blog/testurl.php
//获取网址参数
echo $_SERVER["QUERY_STRING"]."<br>"; #id=5
//获取完整的url
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];
#http://localhost/blog/testurl.php?id=5
//包含端口号的完整url
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
#http://localhost:80/blog/testurl.php?id=5
//只取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
echo dirname($url);
