You need to URL-encode that question mark as %3F , as it is a reserved character. As @wroniasty pointed out, you also need to encode the = as %3D .

header('Location: itms-services://?action=download-manifest&url=http://www.mysite.com/plistReader.php%3Fid%3D123');

Never escape URL characters by hand. Let PHP 5's functions - urlencode() and http_build_query() - do the hard work for you. This avoids issues where some of your GET parameter name/value pairs may have sensitive characters that need to be transmitted eg

<?php
    $base_url = "http://www.example.com/plistReader.php";
    $data = Array("id" => 123, "dangerous" => ":?&= are some sensitive chars");

    $itms_url = "itms-services://?action=download-manifest&url=" . urlencode($base_url . "?" . http_build_query($data));
    header('Location: ' . $itms_url);
?>
