error handler. Later, I’m going to add non-error notices to the mix, and set up an RSS php error handling feed to output these errors, allowing me real-time updates on overall system health. If the error handling stuff sounds like Greek, read up before going further: * PHP http://php.net/manual/en/function.error-reporting.php error handling * set_error_handler() * error_reporting() * trigger_error()When PHP throws any kind of error, the error is assigned an error level, which can be expressed in two ways: an integer or a predefined constant. The constant represents the integer, making the two completely interchangeable. However if you build a custom error handler, you are only http://hotkoehls.com/2009/05/translating-php-error-constants/ given the integer, which doesn’t automagically translate back to the constant value. It’s a heckuva lot easier to recognize E_USER_ERROR instead of the integer 256, so I want to store that error constant for reading purposes. If you find yourself looking at error numbers, and want the matching constant string, use this block of code:lang="php"> switch ($errno) {case 1: $e_type = 'E_ERROR'; break;case 2: $e_type = 'E_WARNING'; break;case 4: $e_type = 'E_PARSE'; break;case 8: $e_type = 'E_NOTICE'; break;case 16: $e_type = 'E_CORE_ERROR'; break;case 32: $e_type = 'E_CORE_WARNING'; break;case 64: $e_type = 'E_COMPILE_ERROR'; break;case 128: $e_type = 'E_COMPILE_WARNING'; break;case 256: $e_type = 'E_USER_ERROR'; break;case 512: $e_type = 'E_USER_WARNING'; break;case 1024: $e_type = 'E_USER_NOTICE'; break;case 2048: $e_type = 'E_STRICT'; break;case 4096: $e_type = 'E_RECOVERABLE_ERROR'; break;case 8192: $e_type = 'E_DEPRECATED'; break;case 16384: $e_type = 'E_USER_DEPRECATED'; break;case 30719: $e_type = 'E_ALL'; break;default: $e_type = 'E_UNKNOWN'; break;} This will give you a string in `$e_type` matching the proper constants.

Join them; it only takes a minute: Sign up systematizing error codes for a web app in php? up vote 4 down vote favorite I'm working on a class-based php web app. I have some places where objects are interacting, and I have certain situations where I'm using error codes to communicate to the end user -- typically when form values are missing or invalid. These are situations where exceptions are unwarranted ( and I'm not sure I could avoid the situations with exceptions anyways). In one object, I have some 20 code numbers, each of which correspond to a user-facing message, and a admin/developer-facing message, so both parties know what's going on. Now that I've worked over the code several times, I find that it's difficult to quickly figure out what code numbers in the series I've already used, so I accidentally create conflicting code numbers. For instance, I just did that today with 12, 13, 14 and 15. How can I better organize this so I don't create conflicting error codes? Should I create one singleton class, errorCodes, that has a master list of all error codes for all classes, systematizing them across the whole web app? Or should each object have its own set of error codes, when appropriate, and I just keep a list in the commentary of the object, to use and update that as I go along? Edit: So I'm liking the suggestions to use constants or named constants within the class. That gives me a single place where I programatically define and keep track of error codes and their messages. The next question: what kind of interface do
