Snappy
Pure PHP implementation of Google Snappy compression algorithm.
This library is a port of javascript snappyjs. Whenever it's possible it's recommended to install PHP Extension, otherwise this lib will register polyfill functions.
Installation
composer require flow-php/snappy
Usage
<?php
$string = 'This is some random string';
echo \snappy_decompress(\snappy_compress($string)); // This is some random string
Performance
PHP Implementation is significantly slower than extension, below you can find a benchmark script and results:
<?php
include __DIR__ . '/../vendor/autoload.php';
$faker = \Faker\Factory::create();
$texts = [];
for ($i = 0; $i < 10_000; $i++) {
$textSize = \Flow\ETL\UniqueFactory::int(100, 5000);
$texts[] = $faker->text($textSize);
}
$snappy = new \Flow\Snappy\Snappy();
echo "Starting Benchmark\n\n";
$flowStart = microtime(true);
foreach ($texts as $text) {
if ($snappy->uncompress($snappy->compress($text)) !== $text) {
die('snappy flow failed');
}
}
$flowEnd = microtime(true);
echo "Snappy Flow time: " . ($flowEnd - $flowStart) . "\n";
$extStart = microtime(true);
foreach ($texts as $text) {
if (\snappy_uncompress(\snappy_compress($text)) !== $text) {
die('snappy ext failed');
}
}
$extEnd = microtime(true);
echo "Snappy PHP Extension time: " . ($extEnd - $extStart) . "\n";
Output:
$ php benchmark_snappy.php
Starting Benchmark
Snappy Flow time: 6.6838178634644
Snappy PHP Extension time: 0.31190991401672
