| 4 | * Merges multiple arrays, recursively, and returns the merged array. |
| 5 | * |
| 6 | * This function is similar to PHP's array_merge_recursive() function, but it |
| 7 | * handles non-array values differently. When merging values that are not both |
| 8 | * arrays, the latter value replaces the former rather than merging with it. |
| 9 | * |
| 10 | * Example: |
| 11 | * $link_options_1 = array( 'fragment' => 'x', 'class' => array( 'a', 'b' ) ); |
| 12 | * $link_options_2 = array( 'fragment' => 'y', 'class' => array( 'c', 'd' ) ); |
| 13 | * // This results in array( 'fragment' => 'y', 'class' => array( 'a', 'b', 'c', 'd' ) ). |
| 14 | * |
| 15 | * @param array $arrays An arrays of arrays to merge. |
| 16 | * @param bool $preserve_integer_keys (optional) If given, integer keys will be preserved and merged instead of appended. |
| 17 | * @return array The merged array. |
