# CRC [](https://travis-ci.org/pburggraf/CRC) [](https://scrutinizer-ci.com/g/pburggraf/CRC/?branch=master)
This is an implementation of the [CRC RevEng Catalogue](http://reveng.sourceforge.net/crc-catalogue/) in PHP 7.x
## How to use
```PHP
calculate('123456789'))); // string(2) "f4"
$crc16AugCcitt = new \PBurggraf\CRC\CRC16\AugCcitt();
var_dump(dechex($crc16AugCcitt->calculate('123456789'))); // string(4) "e5cc"
$crc24 = new \PBurggraf\CRC\CRC24\CRC24();
var_dump(dechex($crc24->calculate('123456789'))); // string(6) "21cf02"
$crc32 = new \PBurggraf\CRC\CRC32\CRC32();
var_dump(dechex($crc32->calculate('123456789'))); // string(8) "cbf43926"
```
## Test
This project uses phpunit to test the validation of crc calculations.
