"The following error types cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICT raised in the file where set_error_handler() is called."This is not exactly true.
User error handler must not modify error context."But do you know WHY you must not modify the error context? This function can be used for defining your own way of handling errors during runtime, for example in applications in which you need to do cleanup of data/files when a critical error happens, or when you need to trigger an error under certain conditions (using settings will have no effect and your error handler will be called regardless - however you are still able to read the current value of error_reporting and act appropriately.Of particular note is that this value will be 0 if the statement that caused the error was prepended by the @ error-control operator.Also note that it is your responsibility to if necessary.If the error-handler function returns, script execution will continue with the next statement after the one that caused an error.It appears that errcontext is (in effect if not literally) created by taking $GLOBALS and adding the non-global local variables as additional entries in that array, then passing the whole thing *by reference*.(You can prove this to be true if you set up a custom error handler and then print_r($errcontext) within it, because $GLOBALS will be printed as a recursive array).
In other words, the language in the manual is misleading, because errcontext is NOT a copy of the variables that existed when the error WAS triggered, but rather is a reference to the *existing LIVE variables* in the calling script.
This includes superglobal variables like $_SERVER, $_POST, $_GET, etc., as well as all user-defined variables in scope.
The following error types cannot be handled with a user defined function: By this function alone you can not catch fatal errors, there is a simple work around.
Below is part of my file which handles errors and exceptions in the application.
Before someone complains I'll add that I do not care that I am using globals, this file is part of my mini framework and without the 'config' variable the application would crash anyways./** * Used for logging all php notices,warings and etc in a file when error reporting * is set and display_errors is off * @uses used in prod env for logging all type of error of php code in a file for further debugging * and code performance * @author Aditya Mehrotra This may be of help to someone, who is/was looking for a way to get a backtrace of fatal errors such as maximum memory allocation issues, which can not be handled with user-defined functions, to pin-point the problem: On a server hosting many sites that share common PHP includes, I set in one spot: I actually used some additional information too from my software that I omitted, but that way, you'll find errors sorted more neatly in for example:- /my/path/php.err-website.com-127.0.0.1-GET-path|index.html?
xyz And that at least helped me tremendously to then further pin-point where the problem is, as opposed to before just seeing the out of memory and not knowing which site/page it was on (as the PHP error only contains the very latest PHP code where it ran out of memory, which usually is just a shared included file, not the actual page).
