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`.
