Usage

This library is a collection of helpful functions related to arrays and array manipulation. They are included by the vendor autoloader automatically. The functions have a namespace of pointybeard\Helpers\Functions\Arrays

The following functions are provided:

• array_is_assoc(array $input) : bool
• array_remove_empty(array $input, int $depth=null) : ?array
• array_insert_at_index(array &$array, int $index, mixed ...$additions) : void

Example usage:

<?php

include __DIR__ . '/vendor/autoload.php';

use pointybeard\Helpers\Functions\Arrays;

var_dump(Arrays\array_is_assoc(['a' => 1, 'b' => 2]));
// bool(true)

var_dump(Arrays\array_is_assoc([4, 5, 6, 7]));
// bool(false)

$a = [1, 2, 3, 4];
Arrays\array_insert_at_index($a, 2, "apple", "banana", "orange");
print_r($a);
// Array
// (
//     [0] => 1
//     [1] => 2
//     [2] => apple
//     [3] => banana
//     [4] => orange
//     [5] => 3
//     [6] => 4
// )

$a = [1, 3, 'animal' => 'chicken', 1, 2, 3, 4];
Arrays\array_insert_at_index($a, 4, ['food' => 'cabbage']);
print_r($a);
// Note that array key 'food' is not preserved
// Array
// (
//     [0] => 1
//     [1] => 3
//     [animal] => chicken
//     [2] => 1
//     [3] => cabbage
//     [4] => 2
//     [5] => 3
//     [6] => 4
// )

print_r(Arrays\array_remove_empty([
    1, 2, 3, 4, '', ['a', 'b', 'c', '', 'e']
]));
// Array
// (
//   [0] => 1
//   [1] => 2
//   [2] => 3
//   [3] => 4
//   [5] => Array
//     (
//       [0] => a
//       [1] => b
//       [2] => c
//       [4] => e
//     )
// )
