What are the potential pitfalls of overwriting variables when adding multiple videos to a playlist in PHP?

When adding multiple videos to a playlist in PHP, one potential pitfall is overwriting the same variable each time a new video is added, resulting in only the last video being stored. To solve this issue, you can use an array to store all the video information and then loop through the array to access each video. 

// Initialize an empty array to store video information
$playlist = [];

// Add multiple videos to the playlist
$video1 = ['title' => 'Video 1', 'url' => 'video1.mp4'];
$video2 = ['title' => 'Video 2', 'url' => 'video2.mp4'];

$playlist[] = $video1;
$playlist[] = $video2;

// Loop through the playlist to access each video
foreach ($playlist as $video) {
    echo 'Title: ' . $video['title'] . ', URL: ' . $video['url'] . '<br>';
}
