Compatibility notes =================== [](#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`.
