$flatten

$flatten Returns a flattened array of items
Usage
<array> $flatten(<data1:variant>[,<data2:variant>[,...]])
Description

Returns an array of items built from the passed arguments with the following rules:

- If an argument is a scalar value then the argument itself is appended to the result.
- If an argument is an array then each contained item is appended to the result.
- If an argument is a hash then each contained value is appended to the result.

A simple example of usage is to merge N arrays into a new one. (Please note that for merging one array into another the array concatenation operator is more efficient).
