I compare them with this function:
function array_diff_assoc_recursive($array1, $array2){
foreach($array1 as $key => $value){
if(is_array($value)){
if(!isset($array2[$key])){
$difference[$key] = $value;
}
elseif(!is_array($array2[$key])){
$difference[$key] = $value;
}
else{
$new_diff = array_diff_assoc_recursive($value, $array2[$key]);
if($new_diff != FALSE)
{
$difference[$key] = $new_diff;
}
}
}
elseif(!isset($array2[$key]) || $array2[$key] != $value){
$difference[$key] = $value;
}
}
return !isset($difference) ? 0 : $difference;
}
echo "<pre>";
print_r(array_diff_assoc_recursive($array1, $array2));
echo "</pre>";
The result is:
array(1) {
[0]=>
array(1) {
["12345"]=>
array(1) {
["fileName"]=>
string(46) "monkey.jpg"
}
}
}
This is working well. But what I would need is, both of the difference values - the original and the new one like this:
array(1) {
[0]=>
array(1) {
["12345"]=>
array(2) {
["fileName1"]=>
string(46) "monkey.jpg"
["fileName2"]=>
string(46) "monkei.jpg"
}
}
}
I tried to add this line $old_diff = array_diff_assoc_recursive($array2[$key], $value);
but it did not work out.
