How do you stop PHP from displaying those nasty error messages? Thanks

Write good code without errors :) j/k

You can turn down the error level for php messages in the php.ini file.

Here's the blurb from the php.ini file

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; error_reporting is a bit-field. Or each number up to get desired error
; reporting level
; E_ALL - All errors and warnings
; E_ERROR - fatal run-time errors
; E_WARNING - run-time warnings (non-fatal errors)
; E_PARSE - compile-time parse errors
; E_NOTICE - run-time notices (these are warnings which often result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it's automatically initialized to an
; empty string)
; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
; initial startup
; E_COMPILE_ERROR - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR - user-generated error message
; E_USER_WARNING - user-generated warning message
; E_USER_NOTICE - user-generated notice message
;
; Examples:
;
; - Show only errors
;
;error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR
;
; - Show all errors except for notices
;
error_reporting = E_ALL & ~E_NOTICE

Of course if you are on a shared host by renting space on another server you won't be able to turn off error reporting.

Take a look at what the error is and fix it. PHP only gives you errors if you have made a mistake.

Absolutely, correct the problems and there won't be any errors.

I agree with the above; fix the error. But to suppress the errormessage you can place an @ before a fuction... this won't work for all of them.
