Are there any potential pitfalls to be aware of when using the srand and rand functions in PHP for generating random numbers?

One potential pitfall when using srand and rand functions in PHP is that if srand is not called before rand, the random numbers generated by rand may not be truly random. To avoid this issue, always call srand before using rand to ensure that the random number generator is properly seeded. 

<?php
// Seed the random number generator with the current timestamp
srand(time());

// Generate a random number between 1 and 100
$randomNumber = rand(1, 100);

echo $randomNumber;
?>
