How to remove everything except the image url?

Question

PHP

Good afternoon, you need a regular expression that will find only the url of the image in the entire text, and delete everything else. Partially copes with this

$text = preg_replace('~(https?://\S+)|.~su', '$1', $text);

, but a little different :(
For example, there is a text:
dsfsodc123<123>sad https://i.imgur.com/mtbl1cr.jpg weqwe
As a result, it should display https://i.imgur.com/mtbl1cr.jpg
Please tell me second day suffering :)

Answer 1

$text = preg_replace('~.*?(https.*jpg).*~g', '$1', $text);  //https://i.imgur.com/mtbl1cr.jpg

Answer 2

$re = '/http(?:s?):\/\/.+?\.(?:jpg|jpeg|png)/s';
$str = '...';

preg_match_all($re, $str, $matches);
$urls = $matches[0];
