The answer is in the editor's note that you quoted, two paragraphs after you snipped the quote: "if (!($type & error_reporting())) return;" $type is the error code..i.e. the first parameter passed to your error handler. Add that line to the top of your error handling function and it will behave the way you expect. PHP's error reporting value is a bitmask...a combination of all of the error type constants that you want PHP to report. The line of code above takes the current error's bit value and does a bitwise AND with the error reporting level. If the result is 0, that means that the current error's bit value is not turned on in the current error reporting level. If this is so, then the line above will return from your error handling function without doing anything...effectively ignoring the error. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] set_error_handler() Keeps Triggering Errors
Hi Earnest. I found these user notes in the PHP manual, but, it's confusing
and seems to be a bit contradictory:
-[snip]-
error_reporting() has no effect if you have defined your own error handler
with set_error_handler()
[Editor's Note: This is not quite accurate.
E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR and
E_COMPILE_WARNING error levels will be handled as per the error_reporting
settings.
All other levels of errors will be passed to the custom error handler
defined by set_error_handler().
-[/snip]-
PHP's error-handling seems to need to re-working. I just can't get this to
work after having tried some other things I found online. All I want is for
PHP to NOT report E_NOTICE errors, but, there seems to be no way to do this,
even if I re-define the E_NOTICE constant vars.
Thanks.

It's somewhere in the docs - can't remember where just now, I believe
isomewhere in the user comments for error_handler:
your error_handler gets _all_ type of error,warning,notice, regardless of
the actual setting of error_reporting (which only decides if the
error/warning/notice gets sent to the client or not).

Might point to a dynamic variable named target:
gets me
Notice: Undefined variable: target in /www/test/test.php on line 4
Do a grep for "target" on your source files.

[PHP] set_error_handler() Keeps Triggering Errors
When I use set_error_handler('error_function') in my scripts, errors are
constantly being triggered that I've never seen before. If I comment the
handler function out, the errors go away. I have the error reporting set
very loosely: error_reporting (E_ERROR | E_USER_ERROR) - so not sure why it
keeps triggering an error, because the error I keep getting is:
Undefined variable: target
This is the same error message no matter what script I run. I don't even use
a variable named $target anywhere in any of my scripts, so, this is
baffling. And this seems like an E_NOTICE error message, but, I'm only
asking for E_ERROR and E_USER_ERROR notices.
My error handling function is fairly simple. It just loads the error info in
a session var then sends the user to the error page, which reads the error
info from the session vars and displays it.
function show_error($type, $msg, $file, $line, $context) {
// Setup error message in Session var...
$_SESSION['error']['type'] = $type;
$_SESSION['error']['msg'] = $msg;
$_SESSION['error']['file'] = $file;
$_SESSION['error']['line'] = $line;
header("Location:./error_page.php");
}
Anyone have any clues why when I set_error_handler to the above function
errors are being triggered for every page?
