What are some best practices for optimizing PHP code that involves random data selection?

When optimizing PHP code that involves random data selection, one best practice is to use the `mt_rand()` function instead of `rand()` for better random number generation. Additionally, pre-generating a shuffled array of data and selecting elements from it can improve performance compared to repeatedly selecting random elements from a large dataset. 

// Generate a shuffled array of data
$data = range(1, 1000);
shuffle($data);

// Select a random element from the shuffled array
$randomElement = $data[array_rand($data)];
