preg_match_all specific directory/path using php

Question

I am am trying to get all links from a page but i would like to match specific directory/path. i am currently using the code below:

preg_match_all("/a[\s]+[^>]*?href[\s]?=[\s\"\']+(.*?)[\"\']+.*?>([^<]+|.*?)?<\/a>/is", $sPageContent, $aResults);

the above code gets all the link of the page but i need s solution that would get links from specific directory, I like to match directories/paths with /music/music/.

For example, I have these links:

https://www.example.co.uk/music/music/397/adoramus-te/
https://www.example.co.uk/music/music/3113/obsesi/
https://www.example.co.uk/music/music/2707/the-piano/
https://www.example.co.uk/music/music/2677/irreemplazable/
https://www.example.co.uk/music/music/25981/lo/
https://www.example.co.uk/music/top/1243/core/
https://www.example.co.uk/music/top/12/late/
https://www.example.co.uk/music/top/13/new/

From the links above, I want to get all links that looks like these:

https://www.example.co.uk/music/music/397/adoramus-te/
https://www.example.co.uk/music/music/3113/obsesi/
https://www.example.co.uk/music/music/2707/the-piano/
https://www.example.co.uk/music/music/2677/irreemplazable/
https://www.example.co.uk/music/music/25981/lo/

but ignore every other links

You might use for example DOMDocument to get the data, and then get all the anchors from it.

Then use a pattern to match /music/music/ from the first forward slash after https://

^https?://[^/]+/music/music/\S+$

Explanation

^ Start of string
https?:// Match the protocol with optional s
[^/]+ Match 1+ times any char except /
/music/music/ Match literally
\S+ Match 1+ times a non whitespace char
$ End of string

Regex demo | Php demo

Example code

$dom = new DOMDocument();
$dom->loadHTML($data);
$anchors = $dom->getElementsByTagName("a");

foreach ($anchors as $anchor) {
    $url = $anchor->getAttribute("href");
    if (preg_match("~^https?://[^/]+/music/music/\S+$~", $url)) {
        echo $url . PHP_EOL;
    }
}

Output

https://www.example.co.uk/music/music/397/adoramus-te/
https://www.example.co.uk/music/music/3113/obsesi/
https://www.example.co.uk/music/music/2707/the-piano/
https://www.example.co.uk/music/music/2677/irreemplazable/
https://www.example.co.uk/music/music/25981/lo/
