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];
    }
}
