drupal_array_merge_deep_array
function drupal_array_merge_deep_array
drupal_array_merge_deep_array($arrays)
Merges multiple arrays, recursively, and returns the merged array.
This function is equivalent to drupal_array_merge_deep(), except the input arrays are passed as a single array parameter rather than a variable parameter list.
The following are equivalent:
- drupal_array_merge_deep($a, $b);
- drupal_array_merge_deep_array(array($a, $b));
The following are also equivalent:
- call_user_func_array('drupal_array_merge_deep', $arrays_to_merge);
- drupal_array_merge_deep_array($arrays_to_merge);

Code
function drupal_array_merge_deep_array($arrays) { $result = array(); foreach ($arrays as $array) { foreach ($array as $key => $value) { // Renumber integer keys as array_merge_recursive() does. Note that PHP // automatically converts array keys that are integer strings (e.g., '1') // to integers. if (is_integer($key)) { $result[] = $value; } // Recurse when both values are arrays. elseif (isset($result[$key]) && is_array($result[$key]) && is_array($value)) { $result[$key] = drupal_array_merge_deep_array(array($result[$key], $value)); } // Otherwise, use the latter value, overriding any previous value. else { $result[$key] = $value; } } } return $result; }
