Okay...
Well, even though I've yet to convince Derick and a few others... I did
see enough interest in this to create a patch. This creates two new
directives: error_redirect (bool) which turns this on/off, and
error_redirect_url (string) which is the URL to redirect to upon error.
In order for these directives to have any effect, the headers (of
course) must not have been already sent. This means that either output
buffering must be enabled, or the script never got around to outputting
anything. This patch will allow users to handle every error PHP
generates if desired (including E_PARSE, etc).
The URL which is redirected to is passed the following parameters via a
GET statement:
errno - The error number (i.e. E_PARSE, whatever)
Errfile - The path/file of the effected file
Errline - The line which the error occurred
Errmsg - The message provided describing the error:
If the redirection fails (i.e. because headers had already been sent,
whatever) the standard PHP error routine is used.
Disclaimer: This is totally meant to be RFC at this point. It works, but
Its not very friendly right now with the other error stuff (i.e.
error_prepend, etc). If I can get a +1 on this concept, I'll clean
things up before I commit.
