PHP два массива разница слияние рекурсивное
function array_merge_recursive_ex(array $array1, array $array2)
{
$merged = $array1;
foreach ($array2 as $key => & $value) {
if (is_array($value) && isset($merged[$key]) && is_array($merged[$key])) {
$merged[$key] = array_merge_recursive_ex($merged[$key], $value);
} else if (is_numeric($key)) {
if (!in_array($value, $merged)) {
$merged[] = $value;
}
} else {
$merged[$key] = $value;
}
}
return $merged;
}
