How-to: Get Current Url in PHP with or without Query String

In each PHP website, we need to find out the current URL of the page, and here’s the PHP code to find out the current URL of the page a user is browsing with or without the query string.

function currentUrl( $trim_query_string = false ) {
    $pageURL = (isset( $_SERVER['HTTPS'] ) && $_SERVER['HTTPS'] == 'on') ? "//" : "//";
    $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
    if( ! $trim_query_string ) {
        return $pageURL;
    } else {
        $url = explode( '?', $pageURL );
        return $url[0];
    }
}

I like to keep such functions in a helpers class so I can use them anywhere in the app. To use it in a PHP class you can use the following code:

public function currentUrl( $trim_query_string = false ) {
    $pageURL = (isset( $_SERVER['HTTPS'] ) && $_SERVER['HTTPS'] == 'on') ? "//" : "//";
    $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
    if( ! $trim_query_string ) {
        return $pageURL;
    } else {
        $url = explode( '?', $pageURL );
        return $url[0];
    }
}
