PHP - Getting Current URL

I'm working on this page: http://localhost/projectname/custom.php
Both <?php echo $_SERVER['REQUEST_URI']; ?> and <?php echo $PHP_SELF; ?> don't give full location. What should I use to grab the full url location?

Answer 1

function selfURL()
{
$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s;
$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI'];
}
function strleft($s1, $s2) { return substr($s1, 0, strpos($s1, $s2)); }

Answer 2

There isn't a native method as far as I know, but you could use this:
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;
}

If you are trying to add variables back onto the end of an URL that you are passing through a link tracking script, for example, you could try this:
$URI = array();
foreach($_GET as $key=>$val)
{
if ($key!="link"&&$key!="id"&&$key!="type") $URI[] = "$key=".urlencode($val);
}
if (sizeof($URI)>0) $link.="&".join("&",$URI);
In this case, "link", "id" and "type" were the variables I needed for the tracking, but the URL I wanted to track had a variable on the end of it that got stripped off by my script as if it was part of the query being sent to it; I needed the add it back to the link URL before passing it to header("Location:".$link).
If this is what you are trying to achieve this works great and is shorter than above example.

check this one... a bit long and dirty but works good...
function absolutizeUrl ( $u, $p )
{
$url = parse_url( $u );
$page = parse_url( $p );
if ( strpos( $u , '/' ) === 0 )
{
//already absolute
} else {
$basePath = '';
if (
isset( $page[ 'path' ] )
&& strpos( ltrim( $page[ 'path' ], '/' ), '/' )
)
{
$baseTokens = explode( '/', $page[ 'path' ] );
array_pop( $baseTokens ); // strip basename
$baseTokens[] = $u;
$u = join( '/', $baseTokens );
}
}
if ( ! isset( $url[ 'host' ]))
{
$u = 'http://'.$page[ 'host' ].'/'.ltrim( $u, '/' );
}
return $u;
}

I found this code very helpful
$protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https') ===
FALSE ? 'http' : 'https'; // Get protocol HTTP/HTTPS
$host = $_SERVER['HTTP_HOST']; // Get www.domain.com
$script = $_SERVER['SCRIPT_NAME']; // Get folder/file.php
$params = $_SERVER['QUERY_STRING'];// Get Parameters occupation=odesk&name=ashik
$currentUrl = $protocol . '://' . $host . $script . '?' . $params; // Adding all
echo $currentUrl;
