PHP: How to Get the Current Page URL

Sometimes, you might want to get the current page URL that is shown in the browser URL window. For example if you want to let your visitors submit a blog post to Digg you need to get that same exact URL. There are plenty of other reasons as well. Here is how you can do that.

Add the following code to a page:

[code language=”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;
}
[/code]

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

[code language=”php”]
echo curPageURL();
[/code]

Sometimes it is needed to get the page name only. The following example shows how to do it:

[code language=”php”]
function curPageName() {
return substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
}

echo "The current page name is ".curPageName();
[/code]
