+
+PHP Polyfill
+============
+
+This project is a complement to [symfony/polyfill](https://github.com/symfony/polyfill)
+and provides some additional functions and workarounds.
+
+The symfony project will only accept contributions that are 100% compatible
+with the native PHP implementation.  In many cases, this isn't actually
+possible - it’s often why the functions were added to PHP in the first place!
+
+So, this project provides implementations that are often “good enough” to get
+your application working on old servers.  Restrictions and limitations are
+described below.
+
+Any functions that are subsequently added to symfony/polyfill will be removed
+from here.
+
+Usage
+=====
+
+Add the dependency to your `composer.json` and allow autoloading magic to do the rest.
+
+```json
+{
+    "require": {
+        "fisharebest/php-polyfill": "~1.0",
+    },
+}
+```
+
+The following polyfill libraries will be loaded automatically:
+
+ - `symfony/polyfill` - the core polyfills
+   - `symfony/intl` - polyfills for intl library functions
+   - `ircmaxell/password_compat` - polyfills for password functions
+   - `paragonie/random_compat` - polfills for random number functions
+ - `fisharebest/ext-calendar` - polyfills for the calendar library functions
+
+PHP 5.3
+=======
+
+ - If the server has enabled “magic quotes”, these are removed.
+ - If the server has enabled "bug_compat_42", this is disabled.
+
+
+PHP 5.4
+=======
+
+ - `http_response_code()` - The native function allows you to get the current
+status code, even if it was set using another function, such as `header()`.
+This implementation can only get the current status code if it was also set by
+`http_response_code()`.
+
+PHP 5.5.9 (Ubuntu 14.04 32 bit)
+===============================
+
+- `gzopen()` - Wrongly implemented as `gzopen64()`.
+- `gzseek()` - Wrongly implemented as `gzseek64()`.
+- `gztell()` - Wrongly implemented as `gztell64()`.
+
+Contributions
+=============
+
+Please follow the existing code style and write unit-tests where you can.
+
+License
+=======
+
+This package is dual licensed under both the [MIT](LICENSE-MIT.md) and
+[GPLv3](LICENSE-GPLv3.md) licenses.  Use whichever makes you happiest.
