Getting the full address of the current page in PHP requires a combination of various functions and references, including domain name or host address, web page address, URL parameters, user agent, port number, etc.

Understanding based on functions

PHP implementation:

echo $_SERVER['HTTP_HOST']."
"; #localhost

The code is as follows

代码如下

复制代码

//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'];
#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);

Copy code

代码如下

复制代码

/**
* 获取当前页面地址
*
* @author bKjia.c0m
*/
function getPageUrl() {
$pageURL = 'http';

if ($_SERVER["HTTPS"] == "on") {
$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;
}

//Get the domain name or host address

//Get the web address echo $_SERVER['PHP_SELF']."
"; #/blog/testurl.php

#http://localhost:80/blog/testurl.php?id=5 //Get only the path

$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
