What are the potential pitfalls of using inefficient random number generation methods in PHP, and how can they be avoided?

Using inefficient random number generation methods in PHP can lead to predictable or biased results, compromising the security and integrity of your application. To avoid this, it is recommended to use the `random_int()` function in PHP, which generates cryptographically secure random integers.

// Using random_int() for secure random number generation
$randomNumber = random_int(1, 100);
echo $randomNumber;
