## What is this?
CRC-PHP is a PHP class implementing bitwise CRC-8/16/24/32/64 algorithms.
## Requirements
* PHP 8.0+
* CRC-32 and CRC-64 methods require a 64-bit build of PHP.
## Usage
Calculate the CRC-16/XMODEM result for a string:
use xenocrat\crc;
$crc = crc::crc16_xmodem("foobar");
Read data from disk and calculate the CRC-24/OPENPGP result:
$file = file_get_contents("README.md");
$crc = crc::crc24_openpgp($file);
Test all implementations by comparing a calculated result to a check value:
$results = crc::test_crc8();
$results = crc::test_crc16();
$results = crc::test_crc24();
$results = crc::test_crc32();
$results = crc::test_crc64();
