Answer 1

You are confusing PHP with HTML. Change the code to this:

<select id="faculty" data-rel="chosen" name="stdid">
<option>select student</option>
<?php   
foreach ($student as $s) {
    echo '<option'.set_select("stdid", $s['stdid'], true).' value="'.$s['stdid'].'">'.$s['stdname'].' '.$s['stdid'].'</option>';
}?> 
</select>

Note that setting all the option elements to set_select("stdid", $s['stdid'], true) will become selected="selected" . Read more about set_select .
