PHP - 替换<img>标签并返回src

Question

任务是<img>用<div>标签和src属性替换给定字符串中的所有标签作为内部文本.在寻找答案时,我发现了类似的问题

<?php

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

?>

结果:

this is something with an (image)  in it.

问题:如何升级脚本蚂蚁得到这个结果:

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

这是PHP DOMDocument类擅长的问题:

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

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

$content = $dom->saveHTML();
