flat()

The flat() method creates a new array with all sub-array elements concatenated into it recursively up to the specified depth.
Example.php
<?php use kim\present\utils\arrays\ArrayUtils;
​
$arrayUtils = ArrayUtils::from([
[1, 2, 3],
[[4, 5, 6], [7, 8, 9]],
10
]);
​
//To flat single level array
$arrayUtils->flat();
// expected output: [1, 2, 3, [4, 5, 6], [7, 8, 9], 10]
​
//To flat two level array
$arrayUtils->flat(2);
// expected output: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
