PHP - 替换 <img> 标签并返回 src

Question

任务是替换所有<img>给定字符串中的标签 <div>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script ant得到这个结果:

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

Answer 1

这是 PHP 的 DOMDocument 的问题类(class)擅长:

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

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

$content = $dom->saveHTML();
