merge

line:42 at /lib/Cake/Utility/Set.php
This function can be thought of as a hybrid between PHP's array_merge and array_merge_recursive. The difference to the two is that if an array key contains another array then the function behaves recursive (unlike array_merge) but does not do if for keys containing strings (unlike array_merge_recursive). See the unit test for more information.

Method

(array) public merge ($arr1, $arr2 = null)

Parameters

ParameterTypeCommentDefault
$arr1 array required Array to be merged
$arr2 array optional Array to merge with null

Return

array

Comment

This function can be thought of as a hybrid between PHP's array_merge and array_merge_recursive. The difference
to the two is that if an array key contains another array then the function behaves recursive (unlike array_merge)
but does not do if for keys containing strings (unlike array_merge_recursive).
See the unit test for more information.

Note: This function will work with an unlimited amount of arguments and typecasts non-array parameters into arrays.

@param array $arr1 Array to be merged
