Question: How to upgrade script ant get this result:

this is something with an <div>test.png</div>  in it.

Answer 1

This is the kind of problem that PHP's DOMDocument class excels at:

$dom = new DOMDocument();
$dom->loadHTML($content);

foreach ($dom->getElementsByTagName('img') as $img) {
    // put your replacement code here
}

$content = $dom->saveHTML();

Answer 2

$content = "this is something with an <img src=\"test.png\"/> in it.";
$content = preg_replace('/(<)([img])(\w+)([^>]*>)/', '<div>$1</div>', $content); 
echo $content;
