-Symfony Polyfill / Php70
-========================
-
-This component provides features unavailable in releases prior to PHP 7.0:
-
-- [`intdiv`](http://php.net/intdiv)
-- [`preg_replace_callback_array`](http://php.net/preg_replace_callback_array)
-- [`error_clear_last`](http://php.net/error_clear_last)
-- `random_bytes` and `random_int` (from [paragonie/random_compat](https://github.com/paragonie/random_compat))
-- [`*Error` throwable classes](http://php.net/Error)
-- [`PHP_INT_MIN`](http://php.net/manual/en/reserved.constants.php#constant.php-int-min)
-- `SessionUpdateTimestampHandlerInterface`
-
-More information can be found in the
-[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).
-
-Compatibility notes
-===================
-
-To write portable code between PHP5 and PHP7, some care must be taken:
-- `\*Error` exceptions must be caught before `\Exception`;
-- after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
-  verified using `isset($e['message'][0])` instead of `null !== $e`.
-
-License
-=======

-This library is released under the [MIT license](LICENSE).
