Are there any best practices for optimizing the performance of a random avatar script in PHP?

To optimize the performance of a random avatar script in PHP, it is recommended to preload the avatar images into an array and then randomly select an image from the array. This will reduce the number of file system calls and improve the script's efficiency. 

// Preload avatar images into an array
$avatars = array(
    'avatar1.jpg',
    'avatar2.jpg',
    'avatar3.jpg',
    // Add more avatar images here
);

// Randomly select an avatar from the array
$randomAvatar = $avatars[array_rand($avatars)];

// Use the selected avatar in your script
echo '<img src="avatars/' . $randomAvatar . '" alt="Random Avatar">';
