How to print/retrieve current page link location
Several time we need to print or retrieve current page link location. Or Several time we need to pass the instant page link location. But how to do it? Ok, just I try to give you some hints about this. Just you can add this code on your page head or you can add the following function on your site configuration page.
<?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;
}
?>
Now, you need to call this function on your desired place where you want to print this link location. Call system are as follows:
<?php
echo curPageURL();
?>
I hope it will be helpful.
