What are potential pitfalls of using the rand() function in PHP for generating random numbers?

Using the `rand()` function in PHP for generating random numbers can lead to potential pitfalls because it is not suitable for cryptographic purposes and may not produce truly random values. To address this issue, it is recommended to use the `random_int()` function in PHP, which provides a more secure and reliable way to generate random numbers.

$randomNumber = random_int($min, $max);
