merge() public static method

If each array has an element with the same string key value, the latter will overwrite the former (different from array_merge_recursive). Recursive merging will be conducted if both arrays have an element of array type and are having the same key. For integer-keyed elements, the elements from the latter array will be appended to the former array.
public static merge ( array $a, array $b ) : array
$a array array to be merged to
$b array array to be merged from. You can specifiy additional arrays via third argument, fourth argument etc.
return array the merged array (the original arrays are not changed.)
