3. 10 core/lib/Drupal/Component/Utility/NestedArray.php \Drupal\Component\Utility\NestedArray::mergeDeepArray()

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

This function is equivalent to NestedArray::mergeDeep(), except the input arrays are passed as a single array parameter rather than a variable parameter list.

The following are equivalent:

• NestedArray::mergeDeep($a, $b);
• NestedArray::mergeDeepArray([$a, $b]);

The following are also equivalent:

• call_user_func_array('NestedArray::mergeDeep', $arrays_to_merge);
• NestedArray::mergeDeepArray($arrays_to_merge);

Parameters

array $arrays: An arrays of arrays to merge.

bool $preserve_integer_keys: (optional) If given, integer keys will be preserved and merged instead of appended. Defaults to FALSE.

Return value

array The merged array.
