使命是取代所有< img>带有< div>的给定字符串中的标签标签和src属性作为内部文本.
在寻找答案时我找到了 similar question

<?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.

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

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

$content = $dom->savehtml();
