Random integer number generation

To generate a random integer, we can use random_int() function, which is a library function in PHP, it accepts two arguments start_value and end_value and returns a random integer between start_value and end_value.

PHP program to generate a random integer between the ranges

<?php
    $start = 10;
    $end = 20;
    
    //generating 10 number
    print("random integers between $start and $end...\n");
    for($i=1; $i<=10; $i++)
    {
        print(random_int($start, $end)." ");
    }
    print("\n");
    
    $start = -100;
    $end = 0;    

    //generating 10 number
    print("random integers between $start and $end...\n");
    for($i=1; $i<=10; $i++)
    {
        print(random_int($start, $end)." ");
    }    
?>

Output

random integers between 10 and 20...
15 15 16 17 10 15 15 13 14 13
random integers between -100 and 0...
-84 -4 -68 -36 -18 -56 -53 -31 -98 -94
