file exist

[desithugg]

umm i have a list of picture names

example

$list = "1.png,2.png,dffd.png,3434.png,32245.png,456.png";

now what I want to do is seperate the list and check if each file exists

like

if (file_exists($list)) {
//if it exists i want it to echo <option value='$list'>$list</a>
}

is that possiable to have the script run a loop or something? any sujjestions what functions or where i should look

<?php
$list = "1.png,2.png,dffd.png,3434.png,32245.png,456.png";

$listArray = explode(',', $list);

foreach($listArray as $file){
  if (file_exists($file)) {
    echo "<option value='$file'>$file</a>";
  }
}

?>
