default error handling in a customized one

DynV

I've been using on my site so far the very practical errror raising / error flagging function set_error_handler() as this : trigger_error("You shouldn't do that !", E_USER_ERROR);

However as unique monochrome display of error on the top of the page is satisfactory to the graphically insensitive coder that I am, it's unacceptable and confusing for the average user so I've put in my page a stylized box for the error when they happen but in order to block the default behavior, it seems I'm bound to writing a error handler with set_error_handler()

I'm only interested in catching E_USER_ERROR and would like to keep the default behavior for the other errors, I like the fact that you can tweak the minimum level of error to display through php_flag and I think this won't be available if I use a custom handler.

So am I stuck between the choices of having to customize all the errors or none at all of there's a way to use the default handler for some and custom for others ? If it's none, I guess I'll have to resort in putting the error messages in a variable and look for it in the error reserved space.

Thank you for your help ! 🙂

You shouldn't really be using PHP's error mechanism for handling user errors; it's for programming errors (the "user" in E_USER_ERROR being the user of PHP, not the user of the site. It's to distinguish between errors in using user code - i.e., yours, and errors in using native PHP constructs). In fact, PHP best practices state that display_errors should be turned off on live sites.

But you can use the second argument to [man]set_error_handler[/man] to specify which categories of error the custom handler is to be used for.

If an image if larger than allowed or is already existing a user ?

If not I don't see what programming error should be, looping without a break or streaming without a timeout ? How could any programmer that dares to call him/herself allow those ?

Edit1: After some thinking you meant like making a function and the arguments aren't as expected ? If so can you give other examples, it's the only one off the top of my head.
