UBUNTU LINUX PHP configurare display log error

Per chi sviluppa con php e necessita della visualizzazione degli errori sulle proprie pagine .php, è utile attivare sul file di configurazione php.ini le opportune direttive che di default dovrebbero essere disattivate.

gheryd@gheryd-laptop:~$ cd /etc/php5/apache2/
gheryd@gheryd-laptop:/etc/php5/apache2$ ll
totale 76
drwxr-xr-x 2 root root  4096 2011-05-17 12:37 ./
drwxr-xr-x 5 root root  4096 2010-10-31 10:32 ../
lrwxrwxrwx 1 root root     9 2010-05-08 20:07 conf.d -> ../conf.d/
-rw-r--r-- 1 root root 67631 2011-05-17 12:37 php.ini

gheryd@gheryd-laptop:/etc/php5/apache2$  sudo nano php.ini

o se preferite l'editor grafico

gheryd@gheryd-laptop:/etc/php5/apache2$ sudo gedit php.ini &

In evidenza le direttive con i valori da impostare.

; error_reporting = E_ALL & ~E_DEPRECATED
error_reporting = E_ALL & ~E_NOTICE

; 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.
; It's recommended that errors be logged on production servers rather than
; having the errors sent 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
; Default Value: On
; Development Value: On
; Production Value: Off
; http://php.net/display-errors
display_errors = On

Ricordarsi di riavviare il server apache2:

gheryd@gheryd-laptop:/etc/php5/apache2$ sudo /etc/init.d/apache2 restart
