how can i make a dynamic drop down box in php?
<p>i need in an php file three drop down boxes or multiple select boxes.</p>

<p>the entries from these boxes are in a mysql database.</p>

<p>the single problem is that the entries in the thrid box depend on the second, and the entries in the second depend on the first.</p>
