function drupal_array_merge_deep_array

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);

            // to integers.
