Extract YouTube Video IDs

This function extracts YouTube video IDs from various formats of YouTube URLs.

function extract_youtube_video_id($content) { $pattern = '/https:\/\/(?:www\.)?(youtube\.com\/(?:watch\?v=|embed\/)|youtu\.be\/)([a-zA-Z0-9_-]{11})/'; if (preg_match($pattern, $content, $matches)) { return $matches[2]; // YouTube video ID } return ''; }
