        var data = $("#mform").serialize();
        $.ajax({
            type: "POST",
            data: data,
            url: "test.php",
            dataType: 'json',
            success: function (json) {}
        });
    });
});

php

<?php
echo '<pre>';
print_r($_POST);
/*
结果为：
Array(
    [data] => Array(
        [0] => Array(
            [name] => aa
            [education] => bb

        )
        [1] => Array(

            [education] => bb2
            [age] => cc2
