What are the potential pitfalls of using array_rand() in PHP?

Using array_rand() in PHP may lead to potential pitfalls such as not guaranteeing a truly random selection, as it relies on the system's random number generator which may not be cryptographically secure. To ensure a more secure random selection, it is recommended to use the random_int() function instead.

// Using random_int() for a more secure random selection
$randomIndex = random_int(0, count($array) - 1);
$randomElement = $array[$randomIndex];
