Homephp教程php手册PHP获取当前页面URL函数实例

这篇文章主要介绍了PHP获取当前页面URL函数实例,讲述了一个非常简单实用的获取当前页面URL的函数,并附带说明了server参数的用法,需要的朋友可以参考下

本文实例讲述了PHP获取当前页面URL函数实例,,分享给大家供大家参考。具体实现方法如下:

在PHP中,没有默认的Function来获取目前所在页面的URL,所以今天就向大家介绍一个在PHP获取当前页面完整URL的PHP函数.

函数代码如下,调用时只需要使用 curPageURL() 就行啦:

复制代码 代码如下:

/* 获得当前页面URL开始 */
function curPageURL() {
    $pageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") {    // 如果是SSL加密则加上“s”
        $pageURL .= "s";
    }
    $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
        $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
    } else {
        $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
    return $pageURL;
}
/* 获得当前页面URL结束 */

补充一下server参数说明,代码如下:

复制代码 代码如下:

//获取域名或主机地址 
echo $_SERVER['HTTP_HOST']."
"; #localhost
 
//获取网页地址 
echo $_SERVER['PHP_SELF']."
"; #/blog/testurl.php
 
//获取网址参数 
echo $_SERVER["QUERY_STRING"]."
"; #id=5
 
//获取用户代理 
echo $_SERVER['HTTP_REFERER']."
";
 
//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'];
#?id=5
 
//包含端口号的完整url
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; 
#:80/blog/testurl.php?id=5
//只取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]; 
echo dirname($url);
#
