PHP Error Reporting Production vs Development

Question

What is best practice when setting error reporting on development and production applications? At the moment I have the following:

// development
error_repor         


        

Answer 1

Quoting the php-production.ini that should have come bundled with your PHP:

; PHP comes packaged with two INI files. One that is recommended to be used
; in production environments and one that is recommended to be used in
; development environments.

; php.ini-production contains settings which hold security, performance and
; best practices at its core. But please be aware, these settings may break
; compatibility with older or less security conscience applications. We
; recommending using the production ini in production and testing environments.

and further

; display_errors
;   Default Value: On
;   Development Value: On
;   Production Value: Off

; display_startup_errors
;   Default Value: Off
;   Development Value: On
;   Production Value: Off

; error_reporting
;   Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
;   Development Value: E_ALL
;   Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT

; html_errors
;   Default Value: On
;   Development Value: On
;   Production value: On

; log_errors
;   Default Value: Off
;   Development Value: On
;   Production Value: On

Since you asked for best practise, I suggest you go with that.

Answer 2

For the best error logging experience, set error_reporting to -1 (absolutely everything), turn display_errors off, and set a custom error_log.

Then in the terminal, type tail -f /path/to/error_log. Your notices, warnings and errors will now scroll past in real time, without distorting your web page's display.

It's always worth logging everything. In any environment.
