| Chris@14 | 17 Compatibility notes |
| Chris@14 | 18 =================== |
| Chris@14 | 19 |
| Chris@14 | 20 To write portable code between PHP5 and PHP7, some care must be taken: |
| Chris@14 | 21 - `\*Error` exceptions must be caught before `\Exception`; |
| Chris@14 | 22 - after calling `error_clear_last()`, the result of `$e = error_get_last()` must be |
| Chris@14 | 23 verified using `isset($e['message'][0])` instead of `null !== $e`. |
