我如何PHP-unserialize jQuery序列化的表单？

$form_elements = array(
    'input1' => 'value1',
    'input2' => 'value2',
    'input3' => 'value3',
    'select1' => array(
        'option1' => 'value1',
        'option2' => 'value2',
    ),
    'select2' => array(
        'option1' => 'value1',
        'option2' => 'value2',
    ),
);
$serialized_form = serialize($form_elements);
echo $serialized_form;

$form_elements = unserialize($serialized_form);
foreach ($form_elements as $key => $value) {
    echo "Key: $key, Value: $value<br>";
}

var form_elements = $('#my-form').serialize();
console.log(form_elements);

var form_elements = jQuery.unserialize(form_elements);
console.log(form_elements);
