// Variable to check
$website = "https://www.pakainfo.com";

// Validate website url
if (filter_var($website, FILTER_VALIDATE_URL)) {

} else {
  echo("Enter website URL is not a valid URL");
}
?>

$final_validation .= "([a-z0-9-.]*)\.([a-z]{2,3})";
$final_validation .= "(\:[0-9]{2,5})?";
$final_validation .= "(\/([a-z0-9+\$_-]\.?)+)*\/?";
$final_validation .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?";
$final_validation .= "(#[a-z_.-][a-z0-9+\$_.-]*)?";

$url = 'https://pakainfo.com/';

if (preg_match("/^$final_validation$/i", $url)) {
