Re: [PHP] set_error_handler help
Is there any way to use a class to handle errors? I've tried some stuff like set_error_handler(Error_Handler::logError and such, but with no luck. It accepts a callback type, which is a pseudo type. Basically an array containg the object and the method to use. Eg. $obj = new ErrorHandlingObject(); set_error_handler(array($obj, 'myMethod')); -- Richard Heyes ++ | Access SSH with a Windows mapped drive | |http://www.phpguru.org/sftpdrive| ++ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] set_error_handler help
I beleive you can also do
set_error_handler(array('classname', 'myMethod'));
for static methods.

E_ERROR can't be caught by an error handler...
Try doing it without the E_ALL, since it's going to catch everything
it can by default anyway.

Have you thought about the fact that you're pointing to a function
that's not been defined yet when the error is triggered?
And set_error_handler() returns NULL because there isn't a previously
defined error handler, not because it failed.
Hope this helps.

Note that it's not necessarily returning false here; it could be 0, or
the empty string, or an empty array...use the '===' operator to test
whether two operands are of the same type and evaluate to the same
value.
http://www.php.net/manual/en/language.operators.comparison.php
Noting from the manual that set_error_handler() returns FALSE on error,
or the name of the previously defined error handler (if there was one)
on success, I am thinking it's probably just returning the empty
string--you likely didn't have an error handler set up before.

So replace your '==' with '===' and you should be good to go.

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.

I found these user notes in the PHP manual, but, it's confusing and seems to be a bit contradictory: It's simple: A user defined error handler cannot handle parse errors or compile time errors.

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. 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()
If I'm not mistaken set_error_handler() takes a string that is the name of a function, I am sure in that function you can instantiate whatever class you want. I thought about that. But ideally, what I'm trying to do is trap the errors with a class method (after instantiating) then print out or handle the errors all at once. Kind of like this: pseudocode $myErrors = new ErrorClass; $old_error_handler = set_error_handler( "myErrors-handler" ); // all of these will be caught with my class' method trigger_error( "Error 1", E_USER_WARNING ); trigger_error( "Error 2", E_USER_WARNING ); trigger_error( "Error 3", E_USER_WARNING ); $myErrors-printAllErrors(); /pseudocode Or something along those lines. Using the function to instiate the class and process the error basically makes the class moot. Why would you really need the class in the first place? You would just have the function do all the work. Chris

After thinking about it some more, I'm doing this. Not sure
if this is the best way to go about it, but it allows me to do
what I want:
?
function errorWrapperFunction( ... error_handler_vars ... ) {
global $ErrorClassName;
$ErrorClassName-errorHandlerMethod( ... error_handler_vars ... );
}
class ErrorHandlerClass {
// constructor
function ErrorHandlerClass() {
$GLOBALS["ErrorClassName"] = get_class( $this );
}
}
$old_error_handler = set_error_handler( "errorWrapperFunction" );
?
That way, I can still use my class to do everything else and handle
the errors when and where I need/want.
