A small library that aims to provide a fast way of decoding PHP

serialization format. Use it if you need to migrate large amount of

PHP data and performance is essential.

The library provides only one function::

    >>> import php2json

    >>> php2json.php2json(b's:3:"foo";')

    b'"foo"'

It's goal is to convert PHP serializer string into JSON string as fast

as possible. The assumption is that JSON decoders (such as standard

json module or `ujson`_) are much better optimized than

`phpserialize`_.

.. _ujson: https://pypi.python.org/pypi/ujson

.. _phpserialize: https://pypi.python.org/pypi/phpserialize/

Here's a simple benchmark where I pit phpserialize against php2json

combined with ujson and json::

    phpserialize: 6.60s

    php2json+ujson: 0.15s

    php2json+json: 0.19s

    speedup (ujson): 4337%

    speedup (json): 3485%

Installation

------------

Install with::

    pip install php2json

Tests

-----

Run test with::

    pip install tox

    make clean

    tox .

Benchmark

---------

Run benchmark with::

    pip install -r requirements-test.txt

    make bench

Limitations

-----------

Few limitations apply:

* only deserialization is possible

* PHP objects are not supported

* behaviour is undefined in presence of unicode strings

* input data must adhere to JSON standards, most notably: array keys

  must be strings or values easily convertible to strings (such as

  integers)
