E_USER_WARNING is a 'constant' whose value is a number.
It is not a string.
If you do this:
echo "E_USER_WARNING is set to '", E_USER_WARNING, "'<br />\n";
you will see exactly what number it is.
So whatever you thought was going wrong, this is not it.
In addition...
The check for $query should probably be more like if (strlen($query))
since it's remotely possible that you could screw up badly enough for
$query to start with characters which happen to fall in the range of
0-9, and if that happens to be, say:
0 and user_id = other_table.user_id
then this test will fail, despite having a borked $query as the root
cause of your troubles.
I've got no idea what that mess of stuff about the errcontext is all
about, but I suspect that unless you are ALSO using their same
object-oriented error handling modules, and have included the source
for that, then your error handler is probably puking on itself, and
PHP is probably refusing to do infinite recursion to call the error
handler from within the error handler. Or it *IS* doing exactly that,
and spiking your CPU before it chokes on the time limit (or even
memory limit) in php.ini
If that's not the problem, then I don't see anything here, other than
some icky code style, that is wrong.

Some people have a "gift" link here.
Know what I want?
I want you to buy a CD from some starving artist.
