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);

/**  * 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"] .
