PHP: How to Get the Current Page URL

If you want to get the current page URL that is shown in the browser URL window, Here is how you can do that:

Add the following code to a page:

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;}
?>

You can now get the current page URL using the line:

echo curPageURL();

Sometimes it is needed to get the page name only. The following example shows how to do it:
{
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}
echo "The current page name is ".curPageName();?>
