Replace div with relative id via PHP

Question

There is HTML:

<div id="attachment_21727" class="someclass">
  <img alt="text" src="url" />
  <p class="wp-caption-text">Text</p>
</div>

I need to replace div to another tag. So i need to find this div,find content in it, and replace.

attachment_21727 - relative as attachment_{number}

So i have a function PHP:

$pattern = "/<div id=\"attachment_(.*?)\" (.*?)>(.*?)<\/div>/i";
$replacement = '<figure>$3</figure>';
$content = preg_replace($pattern, $replacement, $content);

But not working...Any ideas?

You need to change your regex like below:-

#<div id=\"attachment_(.*?)\">(.+?)</div>#s

Working snippet:-

<?php

$content = '<div id="attachment_21727" class="someclass">
  <img alt="text" src="url" />
  <p class="wp-caption-text">Text</p>
</div>';

$pattern = "#<div id=\"attachment_(.*?)\">(.+?)</div>#s";



$replacement = '<figure>$2</figure>';

echo $content = preg_replace($pattern, $replacement, $content);

Was about to write an answer but saw this one. To explain what the difference is, the "s" flag in the regex ensures the "." represents any character including newlines. By default it matches any character except newlines. – james_tookey Apr 18 '18 at 12:19
