Default Error Messages in PHP

[ignace]

Hi,

 

I was wondering if it would be possible to use PHP's default error messages? I think this would be quit cool especially when it comes to type checking. Is this possible? And what do you think of such concept?

I am not sure what you mean by use php default error messages, please elaborate, if you want to show your own you can try

You can use trigger_error to raise E_USER_* errors. Aside from that, you cannot use PHP's error handling system.

@rajiv I think Daniel already partially answered my question but what I actually wanted is that when I define a user function and the user gives a wrong format (array instead of string) then it would report that error instead of me writing:

 

__FUNCTION__ expects parameter two to be string, gettype($variable) given.

 

It's possible I think when using the SPL extension:

 

function functionName(SplString $param1, SplString $param2)

You can type hint non-scalar parameter types. It'll result in a run-time fatal error if a non-matching type is given. You could write an RFC at http://wiki.php.net (and send it to the internals list) to have what I believe Java calls automatic boxing and unboxing. This would allow you to pass e.g. primitives like ints to an SplInt without having to do new SplInt(42).
