PHP Error Handling

Quote from menace33 : Had a feeling you weren't looking for help on coding, just a hunch but said it anyways. Anyhow, to answer your question, you could try PHP Compiler [phpcompiler.org]. I've never used it so I could not tell you how feasible it is but perhaps you could compile your code for errors and warnings before ever putting it on a test or production server.

The number of parameters is variable in PHP, so there is no warning or error to generate. It is something that PHP programmers take advantage of regularly, for instance by allowing an object to have a constructor that optionally loads a saved version of its data by passing in an ID.

as you've found out, warnings are considered non-fatal and the script will continue to execute. I think you can override this behaviour with the set_error_handler function.

I.e. set it to die when error code 2 (warning) is encountered

The method I was testing which led to this thread throws a warning: "Missing Argument".

Variable length argument lists are something else.

I finally had the time to look through the links you posted plus another link I posted earlier about handling warnings.

I copied/pasted some basic error handling functions that halt the program upon running into a warning. Thanks.

Excellent! So you decided to add error handling to the code which is what was recommended from the beginning of the thread.

problem is that a warning is not an error

No. I used PHP's set_error_handler function to halt my program when PHP throws a warning. The exact thing I had requested information on. By default, PHP will halt on errors, but will not halt on warnings. Warnings can be dangerous and I don't want the program to continue running if a warning is thrown.

By the by, you have been supremely unhelpful. This quote is the biggest identifier that you really don't know what you are talking about concerning PHP:

Quote from dealgate : You cannot change the default behavior of PHP.

Considering you can modify the PHP.ini file, install plug-ins and modules (e.g. APC) and run all sorts of functions that change how PHP functions (such as the aforementioned set_error_handler), I'd say that you can modify PHP's behavior quite readily.

OK so if someone puts your code on another system, what do you suppose will happen?

it will do exactly what he's programmed it to do?

His error-handling routine is part of the PHP.ini which is a PHP system file. It does not come with the code. My point is that it is not the proper method for handling errors.

Quote from dealgate : His error-handling routine is part of the PHP.ini which is a PHP system file. It does not come with the code. My point is that it is not the proper method for handling errors.

My error-handling routine is contained in a PHP file titled "errorHandler.php", which contains the following code:

I placed an include at the top of my main classes file so that the error handling runs with the program at all times, even on vanilla PHP installations.

So, please stop. You don't know what you're talking about.
