从多个选择框中获取多个数据

I've got next situation:

I have multiple select boxes (that can select multiple choices) and i need that in php to be processed.

A code is next:

<select name="selectusers[]"  multiple>
    <option value="1">John</option>
    <option value="2">Smith</option>
</select>
<select name="selectusers[]"  multiple>
    <option value="1">John</option>
    <option value="2">Smith</option>
</select>
<input type="submit" value="Send" />

So now, in PHP I do the general foreach

<?php
    foreach($select_users as $users){
        ...
    }
?>

But each time I do foreach loop, and i print_r($select_users); inside of foreach, it gives me same result like:

Array([0]=>Array([0]=>30)[1]=>Array([0]=>33))
Array([0]=>Array([0]=>30)[1]=>Array([0]=>33))

What should I do?

Thank you.

You need to change the name of your select:

<select name="selectusers[]"  multiple>
    <option value="1">John</option>
    <option value="2">Smith</option>
</select>
<select name="selectusers2[]"  multiple>
    <option value="1">John</option>
    <option value="2">Smith</option>
</select>
<input type="submit" value="Send" />

Try this.
