从php重定向时如何隐藏查询参数

<form id="redirectForm" action="destination.php" method="post">
    <input type="hidden" name="param1" value="value1">
    <input type="hidden" name="param2" value="value2">
</form>

<script>
    document.getElementById("redirectForm").submit();
</script>

<?php
    $param1 = $_POST['param1'];
    $param2 = $_POST['param2'];
    // 处理参数值...
?>
