I think you may have a logic error. Try this as your loop:

foreach ($title as $opt) {
    $sel = '';
    if (in_array($opt, $mytitle)) {
        $sel = ' selected="selected" ';
    }
    echo '<option ' . $sel . ' value="' . $opt . '">' . $opt . '</option>';
}

small modification, if u kept the code this way, it will show all results as Selected. so what to do is

if (in_array($opt, $mytitle)) {         $sel = ' selected="selected" '; echo '<option ' . $sel . ' value="' . $opt . '">' . $opt . '</option>';     }else{ echo '<option value="' . $opt . '">' . $opt . '</option>'; }

Use the in_array() function.

for ($i=0; $i<=14; $i++) {
  if(in_array($title[$i], $mytitle)){
    echo "<option selected value='$title[$i]'>$title[$i]</option>";
  }else {
    echo "<option value='$title[$i]'>$title[$i]</option>";
  }
}

Very simple with the help of jQuery where the select has the id test

$('#test option').attr('selected', 'selected');
