HI, whenever you post your form at that time all the fields are posted on the php script, where you can get array of that textbox variable by using for loop.

ex: 
    $textboxarr = array();
    for($i = 0;$i<count($_POST['mytext']);$i++){
             $textboxarr = $_POST['mytext'][$i];
    }

now you having your all text boxes in the $textboxarr.try this.

Thanks.

Use it like this

<head>
<title>Dynamic Form</title>
<script language="javascript">
function changeIt()
{
my_div.innerHTML = my_div.innerHTML +"&ltbr><input type='text' name='mytext[]'>"
}
</script>
</head>
<body>
<form name="form" action="post" method="">
<input type="button" value="add another textbox" onClick="changeIt()">
<div id="my_div">
<input type="submit" value="save">
</body>

In php you will be able to use it as an array like

$_POST['mytext'][0], $_POST['mytext'][1] etc... or you can use a foreach loop for $_POST['mytext']
