- The example below shows the handling of internal exceptions by
- triggering errors and handling them with a user defined function. It then
- restores the original PHP error handling:
<example>
<title>
- Error handling with <function>set_error_handler</function>,
- <function>trigger_error</function> and
- <function>restore_error_handler</function>
+ Decide if <function>unserialize</function> caused an error, then
+ restore the original error handler.
