You can give friendlier error messages than PHP if you use your
own error handler.
It is important to note that your error handler will not have the responsibility for
dealing with all error types. Some errors, such as parse errors and fatal runtime errors,
still trigger the default behavior. If this behavior concerns you, make sure that you check
parameters carefully before passing them to a function that can generate fatal errors and
trigger your own E_USER_ERROR level error if your parameters are going to cause failure.
Here’s a useful feature: If your error handler returns an explicit false value, PHP’s
built-in error handler will be invoked.This way, you can handle the E_USER_* errors
yourself and let the built-in handler deal with the regular errors.

site and tailor your content appropriately.
