Fixed Array Functions

SplFixedArrays are an implementation of a traditional, bounded array in the PHP standard library.

While they require manual resizing, they're significantly faster than regular arrays or collections when working with large sets of data.

Requirements

Currently, requires PHP 8.4 or above, and Laravel 12+.

Installation

You can install the package via Composer:

composer require petrobolos/fixed-array-functions

Fluent interface

FixedArray is best used with its fluent interface. If you're familiar with Illuminate collections, you'll feel right at home. Provide it an SplFixedArray to get started, or a standard array or collection that will be automatically converted. If you provide any other kind of data, including null, it will be inserted into a new SplFixedArray.

use Petrobolos\FixedArray\FixedArrayable;

// You can start by either instantiating a new instance of FixedArrayable, or by calling its helper method:
// The array provided will be converted internally into an SplFixedArray.
$array = new FixedArrayable([1, 2, 3]);

// You can also use the helper function to do the same thing!
$array = fixedArray([1, 2, 3]);

// Lastly, you can use specific methods to begin building your interface logic:
// The same will happen with this collection.
$array = FixedArrayable::fromCollection(collect([1, 2, 3]);

// From here, you can chain different methods, just like you would a collection.
$result = $array
->addFrom([4, 5, 6])
->resize(20)
->filter(fn ($value) => $value % 2 === 0))
->map(fn ($value) => $value * 2))
->get();

// The result will be a SplFixedArray containing [2, 4, 6] but still with 20 indices.

Static methods

You aren't forced to use the fluent interface and can access methods directly by calling them. This is useful if you only need to do one or two operations on a fixed array.

use Petrobolos\FixedArray;

// Create a fixed array using the create method.
$arr = FixedArray::create();

// Easily push or pop items to and from arrays without worrying about indices.
FixedArray::push('apple', $arr);

// Easily and efficiently merge fixed arrays, regular arrays, and even Illuminate collections.
$everything = FixedArray::merge(
    $arr,
    ['a', 'regular', 'array'],
    collect(['and', 'an', 'illuminate', 'collection']),
);
