PHP Arrays, appending count of array items recursively to an array
Pointless Dribble
Okay This is another weird one from me, i want to thank OIS for helping me out on my last question... which deals with this same kind of funky array manipulation... i studied that code in depth and i feel it has helped me become better with recursive array manipulative functions. However, once again i find my self in another tough spot
Actual Problem
I am trying to write a recursive manipulative function such as this. Except for getting the depth of each array element. It will add incremental count to each array element with a certain depth. The easiest way to see what I'm trying to do is to view the "sample array" and "Desired result Array"... i feel like I'm getting better at understanding these kind of recursive functions. but this one is giving me hell, thanks in advance for any kind of help you can give me with this.
Please disregard the [depth] result of the sample array i already have a function that adds this.
Thanks again,

I think this should work... I wasn't able to test on your example array but it seems to work on a smaller array I made.
Edit: Changed the function now that you've removed the 'depth' keys from your example array. Now it finds the depth on its own. I've also added my test code and output:
<?php
function array_depth_count(&$array, $count=array(), $depth=1) {
foreach ($array as &$value) {
if (is_array($value)) {
$value['count'] = ++$count[$depth];
array_depth_count($value, $count, $depth + 1);
}
}
}
$a = array(array(array(array(0),array(0),array(),array()),0,array()));
echo "Before\n";
print_r($a);
array_depth_count($a);
echo "\n\nAfter\n";
print_r($a);
?>
Output:
Before
Array
(
[0] => Array
(
[0] => Array
(
[0] => Array
(
[0] => 0
)
[1] => Array
(
[0] => 0
)
[2] => Array
(
)
[3] => Array
(
)
)
[1] => 0
[2] => Array
(
)
)
)
After
Array
(
[0] => Array
(
[0] => Array
(
[0] => Array
(
[0] => 0
[count] => 1
)
[1] => Array
(
[0] => 0
[count] => 2
)
[2] => Array
(
[count] => 3
)
[3] => Array
(
[count] => 4
)
[count] => 1
)
[1] => 0
[2] => Array
(
[count] => 2
)
[count] => 1
)
)

I really want to say this will work
function deep(&$layer)
{
$count = 1;
$keys = array_keys($layer);
foreach($keys as $key)
if(is_array($layer[$key]))
deep($layer[$key]);
$layer['depth'] = $count++;
}
(Tested and works fine for me) (Another case of me misunderstanding the question. This should be what you want)
