I would say the API that the web server uses to talk with the PHP engine 
will not change the behavior, what you are looking for is

; This directive controls whether or not and where PHP will output errors,
; notices and warnings too. Error output is very useful during 
development, but
; it could be very dangerous in production environments. Depending on 
the code
; which is triggering the error, sensitive information could potentially 
leak
; out of your application such as database usernames and passwords or worse.
; For production environments, we recommend logging errors rather than
; sending them to STDOUT.
; Possible Values:
;   Off = Do not display any errors
;   stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
;   On or stdout = Display errors to STDOUT
;
; Development Value: On
; Production Value: Off
; https://php.net/display-errors
display_errors = Off
