The example in this article describes an example of the PHP function to obtain the URL of the current page, and shares it with you for your reference. The specific implementation method is as follows:

In PHP, there is no default Function to obtain the URL of the current page, so today I will introduce to you a PHP function that obtains the complete URL of the current page in PHP.

The function code is as follows, you only need to use curPageURL() when calling:

/* 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 */

Add the server parameter description, the code is as follows:

//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); #http://localhost/blog
