Validate YouTube video URL format in PHP using parse_url() function

<?php

$yt_url = "https://www.youtube.com/watch?v=cCO2tPGa-dM";

$url_parsed_arr = parse_url($yt_url);

?>

Array
(
    [scheme] => https
    [host] => www.youtube.com
    [path] => /watch
    [query] => v=cCO2tPGa-dM&t=49s )

 

<?php

$yt_url = "https://www.youtube.com/watch?v=cCO2tPGa-dM";

$url_parsed_arr = parse_url($yt_url);

if ($url_parsed_arr['host'] == "www.youtube.com" && $url_parsed_arr['path'] == "/watch" && substr($url_parsed_arr['query'], 0, 2) == "v=" && substr($url_parsed_arr['query'], 2) != "") {

echo "The URL is a valid YouTube link";

} else {

echo "Not a valid YouTube link";

}

?>

If the URL is a valid YouTube video page link, it will show “The URL is a valid YouTube link” on the web page, otherwise it will show “Not a valid YouTube link” on the page.
