How to make random number ?

Generate a random number using mt_rand. From the php documentation- "If called without the optional min, max arguments mt_rand() returns a pseudo-random value between 0 and RAND_MAX. If you want a random number between 5 and 15 (inclusive), for example, use mt_rand (5, 15)."
 

<?php

  echo mt_rand() . " ";
  echo mt_rand() . " ";

  //generate random number between 5 and 15
  echo mt_rand(5, 15);

?>

sample output :
