Re: Make set_time_limit() timeout a catchable fatal error

Hmm, I think I worded that poorly. A function registered with register_shutdown_function does execute when the max_execution_time is exceeded. What it doesn't let you do is to recover in the same way an error handler would let you. David On 09/03/11 22:56, Hannes Landeholm wrote: > I second making time limit reached catchable.
