What are some alternative methods or functions that can be used in PHP to achieve the same goal of displaying random images on a website?

To display random images on a website in PHP, one alternative method is to use the `scandir()` function to scan a directory containing images, then randomly select an image to display. Another method is to store the image filenames in an array and use the `array_rand()` function to randomly select an image from the array. 

// Method 1: Using scandir()
$directory = 'images/';
$images = array_diff(scandir($directory), array('..', '.'));
$randomImage = $images[array_rand($images)];
echo '<img src="' . $directory . $randomImage . '" alt="Random Image">';

// Method 2: Using an array of image filenames
$imageFiles = ['image1.jpg', 'image2.jpg', 'image3.jpg'];
$randomImage = $imageFiles[array_rand($imageFiles)];
echo '<img src="images/' . $randomImage . '" alt="Random Image">';
