To Get Full URL  in PHP:

In this post, We are discussing about How to get the full URL in PHP.

Have a look at:

php code 
$_SERVER['REQUEST_URI']
[ad type=”banner”]
javascript code 
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Note: That the double quoted string syntax is perfectly correct

  • If we want to support both HTTP and HTTPS, we can use
php code 
$actual_link = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
  • Using this code has security implications. The client can set HTTP_HOST and REQUEST_URI to any arbitrary value

  • Using a ternary statement:
php code 
$url = "http" . (($_SERVER['SERVER_PORT'] == 443) ? "s://" : "://") . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

  • Cross platform method for finding the current URL is:
php code 
$url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Sample code:

javascript code 
function full_path() 
$s = &$_SERVER;
$ssl = (!empty($s['HTTPS']) && $s['HTTPS'] == 'on') ? true:false; 
$sp = strtolower($s['SERVER_PROTOCOL']);
$protocol = substr($sp, 0, strpos($sp, '/')) . (($ssl) ? 's' : '');
$port = $s['SERVER_PORT']; 
$port = ((!$ssl && $port=='80') || ($ssl && $port=='443')) ? '' : ':'.$port;
$host = isset($s['HTTP_X_FORWARDED_HOST']) ? $s['HTTP_X_FORWARDED_HOST'] : (isset($s['HTTP_HOST']) ? $s['HTTP_HOST'] : null);
$host = isset($host) ? $host : $s['SERVER_NAME'] . $port;
$uri = $protocol . '://' . $host . 
$s['REQUEST_URI']; $segments = explode('?', $uri, 2);
$url = $segments[0];
 return $url; }

javascript code 
$url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
  • It works for all webservers (Apache, nginx, IIS, …):

  • we can get full current URL including $_SERVER[‘REQUEST_URI’].

Function:

php code 
function getCurrentUrl($full = true) { 
if (isset($_SERVER['REQUEST_URI {

$parse = parse_url( 
        (isset($_SERVER['HTTPS']) && strcasecmp($_SERVER['HTTPS'], 'off') ? 'https://' : 'http://') .                 	(isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : (isset($_SERVER['SERVER_NAME']) ?  	$_SERVER['SERVER_NAME'] : '')) . (($full) ? $_SERVER['REQUEST_URI'] : null) ); 
 $parse['port'] = $_SERVER["SERVER_PORT"]; // Setup protocol for sure (80 is default)
 return http_build_url('', $parse);
 } 
}

Test code:

javascript code 
// Follow $_SERVER variables was set only for test $_SERVER['HTTPS'] = 'off';
 // on $_SERVER['SERVER_PORT'] = '9999'; 
// Setup $_SERVER['HTTP_HOST'] = 'some.crazy.server.5.name:8088';
 // Port is optional there 
$_SERVER['REQUEST_URI'] = '/150/tail/single/normal?get=param'; 
echo getCurrentUrl(); // http://some.crazy.server.5.name:9999/150/tail/single/normal?get=param 
echo getCurrentUrl(false); 
// http://some.crazy.server.5.name:9999/

  •  Function to handle the URL:
php code 
<?php 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;
 } 
?>

  • HTTPS support:
javascript code 
$current_url = sprint  
     ( '%s://%s/%s', 
      isset($_SERVER['HTTPS']) ? 'https' : 'http',
       $_SERVER['HTTP_HOST'], 
        $_SERVER['REQUEST_URI']
 );

Code:

javascript code 
$base = "http://$_SERVER[SERVER_NAME]:$_SERVER[SERVER_PORT]$my_web_base_path"; 
$url = $base . "/" . dirname(dirname(__FILE__));

  • Here is the another way of solution:
javascript code 
//Fetch page URL by this
 $url = $_SERVER['REQUEST_URI']; 
echo "$url<br />"; 

//It will print
 //fetch host by this

 $host=$_SERVER['HTTP_HOST'];
 echo "$host<br />"; 

//You can fetch the full URL by this 

$fullurl = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
 echo $fullurl;

  • You can use this code:
php code 
print_r($_SERVER);
  • $_SERVER is an array containing information such as headers, paths, and script locations.
  • The entries in this array are created by the web server.
  • $HTTP_SERVER_VARS contains the same initial information, but is not a superglobal.   (Note that $HTTP_SERVER_VARS and $_SERVER are different variables.)
