function _entity_bundle_plugin_array_merge_deep_array in Entity bundle plugin 7

Merges multiple arrays, recursively, and returns the merged array.

This function is pretty much a clone of drupal_array_merge_deep_array() and similar to PHP's array_merge_recursive() function, but it handles non-array values differently. When merging values that are not both arrays, the latter value replaces the former rather than merging with it, and numeric keys are also merged, NOT appended.

Example:

$array_1 = array(
  'test' => array(
    'X',
  ),
  array(
    0 => 'A',
    1 => 'B',
  ),
);
$array_2 = array(
  'test' => array(
    'Y',
  ),
  array(
    0 => 'C',
    1 => 'D',
  ),
);

// This results in array('test' => array('X', 'Y'), 0 => 'A', 1 => 'B', 2 => 'C', 3 => 'D').
$incorrect = drupal_array_merge_deep_array(array(
  $array_1,
  $array_2,
));

// This results in array('test' => array('X', 'Y'), 0 => 'C', 1 => 'D').
$correct = _entity_bundle_plugin_array_merge_deep_array(array(
  $array_1,
  $array_2,
));

Parameters
