Just for good measure, you can also use positive lookbehind's and lookahead's in your regular expressions:

(?<=\[embed\])(.*)(?=\[\/embed\])

You'd use it like this:

$string = "[embed]https://www.youtube.com/watch?v=L3HQMbQAWRc[/embed]";
$pattern = '/(?<=\[embed\])(.*)(?=\[\/embed\])/';
preg_match($pattern, $string, $matches);
echo $match[1];

Here is an explanation of the regex:

(?<=\[embed\]) is a Positive Lookbehind - matches something that follows something else.

(.*) is a Capturing Group - . matches any character (except a newline) with the Quantifier: * which provides matches between zero and unlimited times, as many times as possible. This is what is matched between the groups prior to and after. This are the droids you're looking for.

(?=\[\/embed\]) is a Positive Lookahead - matches things that come before it.

$string = '[embed]https://www.youtube.com/watch?v=L3HQMbQAWRc[/embed]';
$string = str_replace(['[embed]', '[/embed]'], '', $string);

See str_replace

preg_match is what you need.

<?php

$str = "[embed]https://www.youtube.com/watch?v=L3HQMbQAWRc[/embed]";
preg_match("/\[embed\](.*)\[\/embed\]/", $str, $matches);
echo $matches[1]; //https://www.youtube.com/watch?v=L3HQMbQAWRc
