Re: [PHP] require_once and E_WARNING?

Hello all,
According to the PHP Manual, when require or require_once failes, an
E_ERROR is triggered: require() and include() are identical in every way
except how they handle failure. include() produces a Warning while
require() results in a Fatal Error. (With 'Fatal Error' being a link to
E_ERROR).
Thing is, when using a custom error handler via set_error_handler(), it
appears to be triggering an E_WARNING, not an E_ERROR. Using PHP 5.1.4
under Linux.
There are one of three possibilities: I am suffering from a lapse in
lucidity (common), the manual is wrong (possible), or PHP is broken
somehow (unlikely). I'm guessing it's the first, but what am I doing
wrong? I'd like to get a second opinion before submitting a bug. I
searched bugs.php.net but was unable to find anything relevant for 5.1.4.
Code:
function default_error_handler($code, $error, $file, $line) {
switch ($code) {
case E_ERROR:
die (Error: $error);
case E_WARNING:
die(Warning: $error);
default:
die(Something else entirely: $error);
}
}
What happens if you put breaks after the die()? This shouldn't be
necesary, but it wouldn't hurt to try. ;-)
As I see in the example of the PHP manual, a break is put even after an
exit(1) call.
set_error_handler('default_error_handler');
require('This file does not exist. At least not here!');
Have you tried this handler with something more fatal, like a missing
semi-colon or a } missmatch?

That will cause a parse error and the script won't even run.

try it with a call to an undefined function e.g.:
$foo = thisFunctionDoesNotExistAtLeastItHadBetterNot();

I read through the set_error_handler() documentation again though, and I found that: The following error types cannot be handled with a user defined function: E_ERROR[...] So, I'm guessing that the require() functions raise an E_WARNING before the E_ERROR. Seems odd. Perhaps what happens under the hood is that require() calls include(), which would raise an E_WARNING when it fails, then the require() code checks the result of include() and if it failed then it raises the E_ERROR. It pays to RTFM more closely, it seems.

If you comment out the 'set_error_handler' line what happens? Do you get
what you expect (and what should happen) ?
It looks like a pretty simple bug report to me but others may have
reasons why it's not working.

Without the error handler, I get the expected result: A fatal error with
the script dying. That is what makes this so mysterious. Doesn't make
sense that it would raise a different kind of error under different
circumstances. It should have the same value every time.
I'm going to sit on this for a day or so and see what people say before I
toss it over to the bug folks. No sense in bothering them if I'm being a
bonehead. (o;
