README

A lossless data compression library using PHP zlib.

Important

This package is still in development.

While it is considered MVP and stable, it may still undergo breaking changes.

Installation

composer require northrook/compressor

Usage

Compressing

Compress data using the Compressor::compress() function, it has two arguments:

• mixed $data to compress. It is type-checked, and serialized using the native \serialize function if it us not a string,
• int $level of compression, from 0 to 9, defaulting to 9.

$example = \Northrook\Compressor::compress( $_SERVER ) : Compressor;
$example->data;  // Resulting compressed string
$example->report // "Compressed data array, from 3.54kB to 1.41kB, saving 60.17%."

Decompressing

To decompress the data, use the decompress static function, it has two arguments:

• string $data to decompress. Unserialized by default.
• bool $raw Returns the decompressed data as-is.

$server_array = \Northrook\Compressor::decompress( $example ) : mixed;
$server_array // 

Tip

Greater compression may be achieved by pre-serializing the data in some cases.

Just don't forget to set decompress( $data, true ), and apply the appropriate deserializer externally.

Arrays of HTML-like strings typically benefit from using json_encode, typically ~2% smaller than serialize.

Notes

The Compressor class is \Stringable, but also provides the readonly data property for unambiguous access.
