What potential pitfalls should be considered when using setPageOrder() in PHP for randomization?

When using setPageOrder() in PHP for randomization, one potential pitfall to consider is that the same random order may be generated each time the page is loaded, leading to a lack of true randomness. To address this issue, a unique seed value can be used to ensure a different random order is generated each time the page is accessed.

// Set a unique seed value for randomization
$seed = uniqid();
srand(crc32($seed));

// Use setPageOrder() with the unique seed value
setPageOrder($seed);
