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>
