Are there specific guidelines for efficiently using arrays in PHP to store and retrieve image file names?

When storing image file names in an array in PHP, it is important to ensure efficient retrieval of the file names later on. One way to do this is to use associative arrays where the image file names are stored as values with unique keys. This allows for quick and easy retrieval of specific image file names based on their keys. 

// Storing image file names in an associative array
$imageArray = array(
    'image1' => 'image1.jpg',
    'image2' => 'image2.jpg',
    'image3' => 'image3.jpg'
);

// Retrieving image file names from the array
$imageName = $imageArray['image2']; // Retrieves 'image2.jpg'
