HTML多维数组

Question

在下面的代码中，仅显示最后两个表单中的值。我能做错什么？

<form action="" method="post">

<input name="fields[edu][name][]" /> 
<input name="fields[edu][age][]"/> 
<br/><br/>

<input name="fields[edu][name][]" /> 
<input name="fields[edu][age][]"/> 

<br/><br/>
<input name="fields[edu][name][]" /> 
<input name="fields[edu][age][]"/> 

<br/><br/>
<input type="submit" name="submit" value="Submit"/>

if(isset($_POST['submit'])){
    print_r($_POST['fields']);

    foreach($_POST['fields'] as $field){
        echo '<br/>';
        echo 'Hello your name is : '.$field['name'];
        echo '<br/>';
        echo 'Hello your age is : '.$field['age'];
    }
}
