Error function routine

Question

Pls what is the best approach considering (performance, security etc.) to implement an error function. Something in the line of ..

function trap_errors($error_code, $parametrs...)
{
$error_code = array => ('1001 = Error description1', '1002 = Error description2',..etc.
)
}

I dont know if the above makes sense. Any pointers?..

• Your Common Sense: I see no sense in such a function at all. What is your goal? What you're trying to achieve?
• James: Until you give more details as "Col. Shrapnel" requests, let me plug an Open Source project I'm working on that collects errors, sends them to a central reporting app, filters them, emails staff and creates tickets. The ticket system is at elastik.sourceforge.net and you want to look at the ErrorReportingService module (look in the general documentation).

You can define an (global) error handler:

function myErrorHandler($type, $msg)
{
 echo $type . ' ' . $msg;
}
set_error_handler("myErrorHandler");

And trigger an error by your own which arrives the upper defined function:

trigger_error("This is an error!", E_USER_ERROR);

Look here to see the list of error types.

This catches each error in PHP: your ones or the system errors, e.g.

• Frank Nwoko: Thanks but is it possible to convert the error type to an understandable info? Instead of 256 say "System could not process your input.."
• user432219: You can use a converter function where convert the constants to a string by using a switch block.
• Your Common Sense: @Frank you don't need such conversion at all. You have completely misunderstood error handling. You don't have to explain every system error to the user. There are only 2 options - 503 and 404. thats ALL
