How does the count() function in PHP impact the random selection of images in the script?

The issue with the count() function in PHP is that it returns the number of elements in an array, which can affect the random selection of images if not used correctly. To solve this issue, you need to store the count of the array in a separate variable before using it in the random selection process. This ensures that the count remains constant throughout the selection process. 

// Store the count of the array in a separate variable
$imageCount = count($images);

// Randomly select an image using the stored count
$randomImageIndex = rand(0, $imageCount - 1);
$randomImage = $images[$randomImageIndex];

// Display the randomly selected image
echo '<img src="' . $randomImage . '" alt="Random Image">';
