What is the significance of using srand() in PHP for generating random numbers?

Using srand() in PHP is significant because it seeds the random number generator with a specific value, making the generated random numbers more predictable and reproducible. This is especially useful when you want to generate the same sequence of random numbers in different runs of your program. It ensures that the random numbers generated are not truly random, but rather pseudo-random based on the seed value provided. 

<?php
// Seed the random number generator with a specific value
srand(1234);

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

echo $randomNumber;
?>
