js

$(function(){

    $('#add').click(function(){
        var name = $("input[name='name']").val();
        var education = $("input[name='education']").val();

        $('#mtbody').append(html);
    });
    //提交
    $('#sub').click(function(){

        $.each($('#mtbody tr'),function(k){
            var name = $('.name', this).text();
            var education = $('.education', this).text();

            var html = '';
            html += '<input type="text" name="data[' + k + '][name]" value="' + name + '">';
            html += '<input type="text" name="data[' + k + '][education]" value="' + education + '">';
            html += '<input type="text" name="data[' + k + '][age]" value="' + age + '"><br>';
            $('#mdiv').append(html);
        });
        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
            [age] => cc
        )
        [1] => Array(
            [name] => aa2
            [education] => bb2
            [age] => cc2
        )
    )
