compare two associative array and display the difference - php

Question

I have the following Two array results coming from MySQL query result.
Array One (Orignal-Data):
Array
(
[w_a] => Array
(
[0] => Array
(
[cod] => CRR
[pr] => LL
[aid] => VM2254
[gender] => m
[title] =>
)
)
[w_a_ml] => Array
(
)
[w_a_ol] => Array
(
)
[w_a_rl] => Array
(
[0] => Array
(
[rol] => 1
)
)
)
Array Two (Changed-Data)
Array
(
[w_a] => Array
(
[0] => Array
(
[cod] => CRR
[pr] => LL
[aid] => VM2254
[gender] => f
[title] => Mr
)
)
[w_a_ml] => Array
(
[0] => Array
(
[wl] => 255
[care] => Sahan
[heigh] =>
[adam] =>
[instance] => Look
)
)
[w_a_ol] => Array
(
)
[w_a_rl] => Array
(
[0] => Array
(
[rol] => 1
)
)
)
What I wan to achieve from the above two array is to compare and show the result in table format or Inside Form To each Field (Original and New-Change) like below.
FiledsN Original New Change
title Empty Mr
Wl Empty 255
Care Empty Sahan
gender m f
instance Empty Look
I've tried making the array a single array using this function:
function array_single($arr) {
if (!is_array($arr)) {
return FALSE;
}
$res = array();
foreach ($arr as $keys => $values) {
if (is_array($values)) {
$res = array_merge($res, array_single($values));
} else {
$res[$keys] = $values;
}
}
return $res;
}
And then comparing using this:
function diff($new,$old) {
$del=array_diff_assoc($old,$new);
$add=array_diff_assoc($new,$old);
return $diff=array("old"=>$del, "new"=>$add);
}
