How can an array be utilized to map card types to specific image filenames in PHP for a more efficient and organized approach?

Using an array to map card types to specific image filenames in PHP can provide a more efficient and organized approach by centralizing the mapping logic in one place. This allows for easier maintenance and scalability as new card types can be easily added or modified in the array without changing multiple parts of the code. Additionally, it simplifies the retrieval of image filenames based on card types, making the code more readable and manageable.

// Array mapping card types to image filenames
$cardImages = [
    'diamond' => 'diamond.png',
    'heart' => 'heart.png',
    'spade' => 'spade.png',
    'club' => 'club.png'
];

// Example usage to get image filename for a specific card type
$cardType = 'heart';
$filename = $cardImages[$cardType];
echo "Image filename for $cardType card is: $filename";
