Comparing two almost exact arrays
http://php.net/array_diff


  Compares array1 against one or more other arrays and returns the values in array1 that are not present in any of the other arrays. 


// Set the keys matching to the $rowTwo array
$row['release'] = $row['Trelease'];
$row['date'] = $row['dateTime'];

// Unset the original values as we no longer need these
unset($row['Trelease'], $row['dateTime']);

// Compare them:
$difference = array_diff($row, $rowTwo);
$needUpdate = count($difference)!==0;
