PHP: rand() function
Description
PHP rand() function is used to generate a random integer

Syntax:
rand()
rand(minv, maxv)

<?php
$rand1=rand();
$rand2=rand(15,25);
$rand3=rand(-150,300);
echo "Random number without a range : ". $rand1 . "<br />";
echo "Random number between 15 to 25 is " . $rand2 . "<br />";
echo "Random number between -150 to 300 is " . $rand3 . "<br />";
