Question

I have the following line of code in javascript:

(Math.random() + "") * 1000000000000000000

which generates numbers like:

350303159372528000

I tried the same thing in PHP with this:

rand()*1000000000000000000

Which returns:

2.272e+21

I need to use PHP as the number generated will be stored as a SESSION variable and will be used by JavaScript later on.

How do I get PHP to force the number to be an int rather than a float?

---

EDIT PHP seems to struggle with this.

Would it work if I just generated the rand number in PHP saved it to the SESSION and then done the multiplying by 1000000000000000000 in JavaScript?

How would I go about this?

Answer 1

In the end I solved the issue like this:

<?php
error_reporting(0);
 function RandNumber($e){


 for($i=0;$i<$e;$i++){
 $rand =  $rand .  rand(0, 9);  
 }
 return $rand;

 }

 echo RandNumber(18);
// Outputs a 18 digit random number

?>
