What is the significance of the srand function in PHP for generating random numbers?

The srand function in PHP is significant for generating random numbers because it initializes the random number generator with a seed value. This seed value is crucial for ensuring that the sequence of random numbers produced is not predictable and truly random. By using srand, you can control the sequence of random numbers generated by providing a specific seed value. 

<?php
// Set the seed value for the random number generator
srand(time());

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

echo "Random Number: " . $randomNumber;
?>
