BitArray for PHP >= 5.5

PHP BitArray

, _(*1)

BitArray for PHP., _(*2)

This project manipulates compact array of bit values stored internally as strings., _(*3)

The bit arrays may have variable length specified when an object is created using either:, _(*4)

• a specific size;
• a traversable collection;
• a string representation of bits;
• a json representation of bits;
• a slice from another bit array;
• a concatenation from two others bit arrays.

The project provides methods to get and set bits values using PHP natural syntax as well as the iterator facility offered by the PHP foreach language construct. It also provides methods for bitwise logical operations between two bit arrays and, or, xor and the not operation., _(*5)

This project uses:, _(*6)

• PHP Code Sniffer for checking PHP code style
• PHPUnit for unit test (100% covered)
• Sphinx and Doxygen for the documentation

Instructions

Using composer: either, _(*7)

$ composer create-project chdemko/bitarray:1.2.x-dev --dev; cd bitarray

or create a composer.json file containing, _(*8)

{
    "require": {
        "chdemko/bitarray": "1.2.x-dev"
    }
}

and run, _(*9)

$ composer install

Create a test.php file containing, _(*10)

<?php

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

use chdemko\BitArray\BitArray;

$bits = BitArray::fromTraversable([true,false,false,true]);
echo $bits . PHP_EOL;

This should print, _(*11)
