How can the use of srand() and shuffle() functions in PHP be improved for better randomization of data?

The issue with using srand() and shuffle() functions in PHP for better randomization of data is that srand() should be used with caution as it can potentially lead to less random results. To improve randomization, it is recommended to use more secure random number generation functions like random_int() for seeding srand() and then using shuffle() to randomize the data array. 

<?php
// Securely seed srand() using random_int()
$seed = random_int(0, PHP_INT_MAX);
srand($seed);

// Data array to be shuffled
$data = [1, 2, 3, 4, 5];

// Shuffle the data array
shuffle($data);

// Output the shuffled data
print_r($data);
?>
