如果页面有致命错误那么显示在页面上，如果只是警告那么通过代码中添加error_reporting(E_ALL)来显示

; This directive controls whether or not and where PHP will output errors,

; it could be very dangerous in production environments. Depending on the code

; out of your application such as database usernames and passwords or worse.
; It's recommended that errors be logged on production servers rather than
; having the errors sent to STDOUT.

; Off = Do not display any errors
; stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
; On or stdout = Display errors to STDOUT
