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 trigger_error()). It is important to remember that the standard PHP error handler is completely bypassed for the error types specified by error_types unless the callb

I want it to email me as many errors as possible, with the exception of notices. I have the following code http://stackoverflow.com/questions/6217994/php-how-to-use-set-error-handler-to-properly-deal-with-all-errors-except-noti $errstr, $errfile, $errline) { switch ($errno) { case E_NOTICE: case E_USER_NOTICE: $errors = "Notice"; break; case E_WARNING: case E_USER_WARNING: $errors = "Warning"; break; case E_ERROR: case E_USER_ERROR: $errors = "Fatal Error"; break; default: $errors = "Unknown Error"; break; } error_log(sprintf("PHP %s: %s in %s on line %d", $errors, $errstr, $errfile, $errline)); $msg = "ERROR: [$errno] $errstr\r\n". "$errors on line $errline in file $errfile\r\n"; sendErrorEmail($msg); showErrorPage(); exit(1); } function sendErrorEmail($p_errorMsg) { // Parse and sent out the error email... } function showErrorPage() { // Redirect to an error page. } ?> Above is my current setting set_error_handler('globalErrorHandler', E_USER_WARNING);, which seems to be wrong in that it doesn't cover trigger_error() errors. I believe that is because the argument is supposed to be a bitmask instead of just a single error level, but I am not sure how to set it to work for the maximum number of errors/information (except notices). I've seen examples that use E_ALL, but that actually directly causes any code that includes the global error handler stuff to error for me. So anyway, how do I use set_error_handler so that the maximum amount of information can be handled by my custom error handler (so that I can get automatic emails directly when such problems occur, instead of having to review the logs later). php

Saiful Islam 88441626 add a comment| 6 Answers 6 active oldest votes up vote 23 down vote accepted Simple Answer: You can't. See the manual: 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, php error set_error_handler E_COMPILE_WARNING, and most of E_STRICT raised in the file where set_error_handler() is called. For every other error, you can use set_error_handler() EDIT: Since it seems, that there are some discussions on this topic, with regards to using register_shutdown_function, we should take a look at the definition of handling: To me, handling an error means catching the error and reacting in a way that is "nice" for the user and the underlying data (databases, files, web services, etc.). Using register_shutdown_function you cannot handle an error from within the code where it was called, meaning the code would still stop working at the point where the error occurs. You can, however, present the user with an error message instead of a white page, but you cannot, for example, roll back anything that your code did prior to failing. share|improve this answer edited Sep 30 '11 at 20:58 answered Dec 14 '09 at 10:59 Dan Soap 7,38711943 3 Actually you can handle those errors with an user defined function. All you have to do is define register_shutdown_function. See my answer below for a working example I implemented in my website. –jdias Sep 20 '11 at 18:32 Yes, you can. However, there are some downsides to it: see my edit above

Join them; it only takes a minute: Sign up set_error_handler Isn't Working How I Want It To Work up vote 10 down vote favorite 5 I'm taking the leap: my php scripts will ALL fail gracefully! At least, that's what I'm hoping for... I don't want to wrap (practically) every single line in try...catch statements, so I think my best bet is to make a custom error handler for the beginning of my files. I'm testing it out on a practice page: function customError($level,$message,$file,$line,$context){ echo "Sorry, an error has occured on line $line.
"; echo "The function that caused the error says $message.
"; die(); } set_error_handler("customError"); echo($imAFakeVariable); This works fine, returning: Sorry, an error has occured on line 17. The function that caused the error says Undefined variable: imAFakeVariable. However, this setup doesn't work for undefined functions. function customError($level,$message,$file,$line,$context){ echo "Sorry, an error has occured on line $line.
"; echo "The function that caused the error says $message.
"; die(); } set_error_handler("customError"); imAFakeFunction(); This returns: Fatal error: Call to undefined function: imafakefunction() in /Library/WebServer/Documents/experimental/errorhandle.php on line 17 Why isn't my custom error handler catching undefinedd functions? Are there other problems that this will cause?

This is because set_error_handler is meant to be a method of reporting errors thrown by the user error function trigger_error. However, I did find this comment in the manual that may help you: "
