Question

Hello I need to get N numbers from range between 2 big numbers, without the start and end numbers.
The (N) numbers must be on equal intervals… I will try to explain with small numbers:

<?php
$rangeStart = 0;
$rangeEnd = 100;
$n = 9;

In this example i need to get 10,20,30,40,50,60,70,80,90

I have try with ‘for loop’ but it is veeery slow, because I’m using range like 1207083600 ~ 1275512399

Will appreciate any help.

This is what I call slow http://jsfiddle.net/pbF7N/1/
The start and end are timestamps and I need to extract 10 dates…

Something like this maybe:

function nrange($num, $start, $end)
{
        $out = array(); $i = 0;
        $interval = floor(($end - $start) / ($num + 1));
        while ($i++ < $num )
                $out[] = $start + $i * $interval;

        return $out;
}
