How can I get src of video from HTML

on example.com is <video> like:

<video controls="" preload="false" src="http://example.com/video.mp4"></video>

and I would like to get content of src="" which is inside of that <video> tag

(example.com is not my website, I need to use PHP to get to the HTML code and get the src from the video tag)

thank you!

Quick and dirty way

<?php
preg_match_all('#<video .*?src="(.*?)"#', file_get_contents('https://example.com'), $results);

print_r($results[1]);

A better way is to use web scraping/crawling tools like FriendsOfPHP/Goutte
