Is it necessary to manually initialize the random number generator in PHP 5 using srand() or mt_srand()?

In PHP 5, it is not necessary to manually initialize the random number generator using srand() or mt_srand(). The random number generator is automatically seeded with a random value when the PHP script starts running. This ensures that the random numbers generated are truly random.

// No need to manually initialize the random number generator in PHP 5
// Random numbers will be generated automatically

$randomNumber = rand(1, 100);
echo $randomNumber;
