exit dreamwever during development

hi to all

I notice that if I remove "php" in "&lt;?php" I was never encounter exit during my development. But I am just wondering because it was happen only those inside <select> element.

Code:

<select name="classification">
&lt;?php foreach ($arr_classification->result() as $row )
{
    print '<option value="'.$row->sf_classification_id.'">'.$row->name.'</option>';
}
?&gt;
</select>
