<?php | |
function current_page_url() { | |
$url = 'http'; | |
if ($_SERVER["HTTPS"] == "on") | |
$url .= "s"; | |
$url .= "://"; | |
if ($_SERVER["SERVER_PORT"] != "80") | |
$url .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; | |
else | |
$url .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; | |
return $url; | |
} | |
// Now use the function like following: | |
$url = current_page_url(); | |
//or | |
echo current_page_url(); |
