Question

Any random number between 0 to 100 can be generated like this:

<?php
    $min = 0;
    $max = 100;
    $random =  rand($min,$max);
?>

Now I can place this $random anywhere in my file to generate a random number. But the problem is when I place this on more than one place all those places have same value (if one random number is 17 all will be 17).

I am doing something like this to do that in more than one place:

    $random2 =  rand($min,$max);
    $random3 =  rand($min,$max);
    $random4 =  rand($min,$max);
    $random5 =  rand($min,$max);

And placing those in all locations.

Doing so takes more of my space in my script. Is there any better way to do what I want?

Answer 1

Why not making a function?:

function myRand(){
    $min = 0;
    $max = 100;
    return mt_rand($min, $max);
}
echo myRand();

that way you have to call only the function.
