If it is the same attribute value, then can you just get the src attribute directly when getting it? I don’t understand what your needs are

But if you must use PHP regular implementation, you can also use the preg_replace_callback method to replace it. Use regular rules to match src="a.jpg" and replace it with src="a.jpg" data-url=" a.jpg" will do

Can I use jq? The following is the jq method

<code><img  src="1242x225.jpg" />
<script type="text/javascript">
 $("img").each(function(i){
    var img_url = $('img')[i].src;
    var img_name = img_url.substring(img_url.lastIndexOf("/")+1,img_url.length);
    $(this).attr("data-url",img_name);
});
</script>
以下是浏览器打印效果
