+Polyfill unserialize [![Build Status](https://travis-ci.org/dbrumann/polyfill-unserialize.svg?branch=master)](https://travis-ci.org/dbrumann/polyfill-unserialize)
+===
+
+Backports unserialize options introduced in PHP 7.0 to older PHP versions.
+This was originally designed as a Proof of Concept for Symfony Issue [#21090](https://github.com/symfony/symfony/pull/21090).
+
+You can use this package in projects that rely on PHP versions older than PHP 7.0.
+In case you are using PHP 7.0+ the original `unserialize()` will be used instead.
+
+From the [documentation](https://secure.php.net/manual/en/function.unserialize.php):
+
+> Warning: Do not pass untrusted user input to unserialize(). Unserialization can
+> result in code being loaded and executed due to object instantiation
+> and autoloading, and a malicious user may be able to exploit this.
+
+This warning holds true even when `allowed_classes` is used.
+
+Requirements
+------------
+
+ - PHP 5.3+
+
+Installation
+------------
+
+You can install this package via composer:
+
+```
+composer require brumann/polyfill-unserialize "^1.0"
+```
+
+Known Issues
+------------
+
+There is a mismatch in behavior when `allowed_classes` in `$options` is not
+of the correct type (array or boolean). PHP 7.1 will issue a warning, whereas
+PHP 7.0 will not. I opted to copy the behavior of the former.
+
+Tests
+-----
+
+You can run the test suite using PHPUnit. It is intentionally not bundled as
+dev dependency to make sure this package has the lowest restrictions on the
+implementing system as possible.
+
+Please read the [PHPUnit Manual](https://phpunit.de/manual/current/en/installation.html)
+for information how to install it on your system.
+
+You can run the test suite as follows:
+
+```
+phpunit -c phpunit.xml.dist tests/
+```
+
+Contributing
+------------
+
+This package is considered feature complete. As such I will likely not update it
+unless there are security issues.
+
+Should you find any bugs or have questions, feel free to submit an Issue or a Pull Request.
