What are the best practices for handling array data in PHP when trying to extract specific information like thumbnails and comments from images?

When handling array data in PHP to extract specific information like thumbnails and comments from images, it is best to use a combination of array functions such as array_map, array_filter, and foreach loops. By iterating through the array and applying the necessary functions to filter out the desired information, you can efficiently extract the thumbnails and comments from the images. 

// Sample array containing image data
$images = [
    ['name' => 'Image 1', 'thumbnail' => 'thumb1.jpg', 'comment' => 'Beautiful landscape'],
    ['name' => 'Image 2', 'thumbnail' => 'thumb2.jpg', 'comment' => 'Lovely sunset'],
    ['name' => 'Image 3', 'thumbnail' => 'thumb3.jpg', 'comment' => 'Cute animals'],
];

// Extract thumbnails from images
$thumbnails = array_map(function($image) {
    return $image['thumbnail'];
}, $images);

// Extract comments from images
$comments = array_map(function($image) {
    return $image['comment'];
}, $images);

// Output thumbnails and comments
foreach ($thumbnails as $thumbnail) {
    echo "Thumbnail: $thumbnail <br>";
}

foreach ($comments as $comment) {
    echo "Comment: $comment <br>";
}
