I don't think this is possible in PHP. When exit(0); is called. PHP
execution stops. In the manual there is a small comment about exit
inside a register_shutdown_function

[snip]
Multiple calls to register_shutdown_function() can be made, and each
will be called in the same order as they were registered. If you call
exit() within one registered shutdown function, processing will stop
completely and no other registered shutdown functions will be called.

Mathijs:

For MySQL failures I use:

$result = mysql_query($query) or die(report($query,__LINE__ ,__FILE__));


function report($query, $line, $file)
{
echo($query . '<br>' .$line . '<br/>' . $file . '<br/>' .
mysql_error());
}

Perhaps you can modify that for your use.

Cheers,

tedd

It can certainly help you for debugging, but I agree, it's not for production.

I don't really know how others debug, I work alone. But, I do all my
stuff online and use the following function:

function report($query, $line, $file)
{
echo($query . '<br>' .$line . '<br/>' . $file . '<br/>' .
mysql_error());
}

That gives me immediate notice of where the error occurred and what
the error was. When I take my code to production, I simply comment
out the echo().

I used to use a global to do that (show/not show errors), but
consider all my error stuff in is one file, it's easy enough to
comment out what I don't want to show.

Cheers,

tedd
