Question

I have a php script that is run once a minute. The script runs a second script, then sleeps for a given amount of time.

Right now the time is static. 20 seconds each time.

What I need is to randomize the amount of time it sleeps. It can be more than a total of 60 seconds, but not less.

So here is what i have now.

$sleep1 = rand(2,18);
$sleep2 = rand(2,18);
$sleep3 = rand(2,18);
$sleep4 = rand(2,18);
if $sleep1 + $sleep2 + $sleep3 + $sleep4 <= 60 ?

I need to add up all the $sleep variables, and then determine if the total is less than 60. If it is, I need to increase the value of one or more of the variables to make up the difference.

If you can have more than, or do not need exactly 4 $sleep_ variables:

<?php

$time = 0;
$i = 1;
$array = array();

do {
  $sleep{$i} = rand(2,18);
  $array[] = $sleep{$i};
  $time += $sleep{$i};
  $i++;
} while ($time <= 60);

print_r($array);

echo $time;

?>

Gives you something like:

Array
(
    [0] => 5
    [1] => 2
    [2] => 18
    [3] => 9
    [4] => 11
    [5] => 10
    [6] => 3
    [7] => 13
)
