Dividing a integer equally in X parts - php

Question

I'm looking for a efficient way in PHP to divide a number in equal part. Number will always be integer (no float).
Let's say that I have an array $hours with values from "1" to "24" ($hours['1'], etc) and a variable $int containing an integer. What I want to acheive is spreading the value of $int equally in 24 parts so I can assing the value to each corresponding array entries. (Should the number be odd, the remaining would be added to the last or first values in the 24).
Regards,

Answer 1

Here's the algorithm you're looking for; it evenly spreads an integer N over K cells:
for i = 0 to K
array[i] = N / K # integer division
# divide up the remainder
for i = 0 to N mod K
array[i] += 1

Answer 2

Try this code
<?php
$num = 400;
$val = floor($num/24);
for($i=0;$i<24;$i++) {
$arr[$i] = $val;
}
$arr[0] += $num - array_sum($arr);
?>

Answer 3

function split($x, $n)
{
// If we cannot split the
// number into exactly 'N' parts
if($x < $n)
echo (-1);
// If x % n == 0 then the minimum
// difference is 0 and all
// numbers are x / n
else if ($x % $n == 0)
{
for($i = 0; $i < $n; $i++)
{
echo ($x / $n);
echo (" ");
}
}
else
{
// upto n-(x % n) the values
// will be x / n
// after that the values
// will be x / n + 1
$zp = $n - ($x % $n);
$pp = $x / $n;
for ($i = 0; $i < $n; $i++)
{
if($i >= $zp)
{
echo (int)$pp + 1;
echo (" ");
}
else
{
echo (int)$pp;
echo (" ");
}
}
}
}
// Driver code
$x = 5;
$n = 3;
split( $x, $n);
