Re: error handling

It would still be good to have as there are tons of sites that use sessions and plain header() calls - they care of not having the output before processing is done. If E_PARSE error happens after an output the header() can fail bad too with headers sent message. But, if one wants to control well the whole error thing - it would then be possible. -- Maxim Maletsky maxim@php.net Kjartan Mannes <kjartan@zind.net> wrote... : > Monday, November 18, 2002, 11:43:48 AM, John Coggeshall wrote: > > Back on the note that I was discussing (the E_PARSE with a user > > error-handler), Perhaps the issue can be slightly skirted without having > > to code a whole lot...
