PHP Get Address Bar URL Function_PHP Tutorial

To obtain a url address in php, I will use the super global variable $_SERVER, which includes various parameter acquisition, such as HTTP_HOST, PHP_SELF, QUERY_STRING, etc., which will not be introduced here.

Introduction to several functions of PHP to obtain URL

Combine the above functions to get the complete URL address

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']." "; //获取网页地址 echo $_SERVER['PHP_SELF']." "; //获取网址参数 echo $_SERVER["QUERY_STRING"]." "; //来源网页的详细地址 echo $_SERVER['HTTP_REFERER']." "; ?>

Copy code

代码如下	复制代码
// 说明：获取完整URL function curPageURL() { $pageURL = 'http'; if ($_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 domain name or host address
echo $_SERVER['HTTP_HOST']."
";
//Get the web address
echo $_SERVER['PHP_SELF']."
";
//Get URL parameters
echo $_SERVER["QUERY_STRING"]."
";
//Detailed address of the source web page
echo $_SERVER['HTTP_REFERER']."
";
?>

代码如下	复制代码
echo curPageURL(); ?>

The code is as follows

Copy code

// Description: Get the complete URL function curPageURL()

$pageURL = 'http'; if ($_SERVER["HTTPS"] == "on")

}
$pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80")
{
$pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"];
}  
else
