drop down box using php
<p>I have a drop down box it pulls values from db.It will display only one column in drop down box.If i select one column in drop down box,it should display other values in text box.</p>

<p>I have done displaying values in drop down box but i am struck here.If i select a value in drop down corresponding  values has to be displayed in text box</p>

<p>eg: car bmw classc 125hp</p>

<p>here if i select bmw in drop down box i should get that class c and 125ho in text box.</p>
