Combine two arrays on key/value and output combined array with PHP

Question

Racking my brain on this, found many examples of similar situations however the solutions don\'t seem to match up.

I have two arrays being built as the result of SQL que

Answer 1

Assuming your first array as $first and second array as $second

foreach ($first as $key => $each) {
  foreach ($second as $secondeach) {
    if($secondeach['sku'] == $key) {
      $first[$key] = array_merge($first[$key], $secondeach);
      // unset since you do not want LocalSKU value anymore.
      unset($first[$key]['LocalSKU']);
    }
  }
}

$first is your array you wanted.
