array_replace — Replace the elements of the first array with the passed array

Description

array_replace ( array $array1 [, array $... ] ) : array

array_replace() function replaces the value of array1 array with the value of the same key of the subsequent array element. If a key exists in the first array and also exists in the second array, its value will be replaced by the value in the second array. If a key exists in the second array but not in the first array, the element will be created in the first array. If a key only exists in the first array, it will remain unchanged. If multiple replacement arrays are passed, they will be processed in order, and subsequent arrays will overwrite previous values.

array_replace() is non-recursive: it replaces the values ​​of the first array regardless of the type in the second array.
