Arrange and group numbers in an array

[newbtophp]

I need some help, in grouping numbers in lots of 15.

 

Im trying to figure out a way to sort an array of numbers in numerical order, then create a new array which will consist of the numbers being in numerical order and have next to them their group number followed by their order number.

 

This is what i expect it to be like:

 

Input:

 

array("26", "29", "27", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45");

 

 

Output:

 

Array
(
    [26] => 1, 1
    [27] => 1, 2
    [29] => 1, 3
    [30] => 1, 4
    [31] => 1, 5
    [32] => 1, 6
    [33] => 1, 7
    [34] => 1, 8
    [35] => 1, 9
    [36] => 1, 10
    [37] => 1, 11
    [38] => 1, 12
    [39] => 1, 13
    [40] => 1, 14
    [41] => 1, 15
    
    [42] => 2, 1
    [43] => 2, 2
    [44] => 2, 3
    [45] => 2, 4

)

 

This is so far what I've come up with:

 

<?php

$ids = array("26", "29", "27", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45");

//sort them in numerical order...
sort($ids, SORT_NUMERIC);

print_r($ids);
?>

 

All help is greatly appreciated, as I've tried myself and seems pretty complex  :-\

 

Thanks.

//sort them in numerical order...
sort($ids, SORT_NUMERIC);

$i = 0;
$x = 0;
$New = array();
foreach($ids as $v)
{
$T = $i + 1;
$New[$i][] = $T . ", " . $v;
$x++;
if($x ==15)
{
$i++;
}
}

print_r($New);

 

Woops, misread post. New reivion:

 

$ids = array("26", "29", "27", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45");

//sort them in numerical order...
sort($ids, SORT_NUMERIC);

$i = 1;
$x = 1;
$New = array();
foreach($ids as $v)
{
$New[$v] = "$i, $x";
$x++;
if($x == 15)
{
$x = 1;
$i++;
}
}

Counting starts at 0, when you initiate a var at 1 and and compare with == and you need a grouping of 15 you must go one higher, thus count to 16, to use the grouping number you must compare using a greaterThan.

 

if($x == 15)//wrong

if($x == 16)//right

if($x > 15)//right

sort($ids, SORT_NUMERIC);
for($i = 0, $j = 1, $cnt = count($ids); $i < $cnt; $j = (++$i+1)%15)
  $newIds[$ids[$i]] = ceil(($i+1)/15).', '.($j?$j:15);

echo '<pre>',print_r($newIds, 1),'</pre>';
