How can PHP code be used to search for and insert "/embed/" in a YouTube video link?

To search for and insert "/embed/" in a YouTube video link using PHP, you can use a combination of string manipulation functions like strpos() to find the position of the video ID in the link and then insert "/embed/" at that position. You can also use str_replace() to replace the regular YouTube link format with the embedded format.

<?php
$youtube_link = "https://www.youtube.com/watch?v=VIDEO_ID";
$embed_link = str_replace("watch?v=", "embed/", $youtube_link);
echo $embed_link;
?>
