[5] Fix | Delete

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

[6] Fix | Delete

[7] Fix | Delete

* This function is similar to PHP's array_merge_recursive() function, but it

[8] Fix | Delete

* handles non-array values differently. When merging values that are not both

[9] Fix | Delete

* arrays, the latter value replaces the former rather than merging with it.

[10] Fix | Delete

[11] Fix | Delete

* Example:

[12] Fix | Delete

* $link_options_1 = array( 'fragment' => 'x', 'class' => array( 'a', 'b' ) );

[13] Fix | Delete

* $link_options_2 = array( 'fragment' => 'y', 'class' => array( 'c', 'd' ) );

[14] Fix | Delete

* // This results in array( 'fragment' => 'y', 'class' => array( 'a', 'b', 'c', 'd' ) ).

[15] Fix | Delete

[16] Fix | Delete

* @param array $arrays An arrays of arrays to merge.

[17] Fix | Delete

* @param bool $preserve_integer_keys (optional) If given, integer keys will be preserved and merged instead of appended.

[18] Fix | Delete

* @return array The merged array.
