PHP-替换< img>标签并返回src [英] PHP - replace <img> tags and return src

问题描述

任务是将给定字符串中的所有<img>标签替换为<div>标签和src属性作为内部文本. 在寻找答案时，我发现了类似的问题

Mission is to replace all <img> tags in given string with <div> tags and src property as inner text. In search for the answer I found 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:如何升级脚本蚂蚁获得此结果:

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

推荐答案

这是PHP的 DOMDocument 类擅长于:

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();
