Linux setup steps/Configure php.ini

From Nick Jenkins

Configuring PHP.ini (note: for Ubuntu rather than debian, the path is probably /etc/php5/cgi rather than /etc/php5/apache2)

cp /etc/php5/apache2/php.ini /etc/php5/apache2/orig-php.ini
nano /etc/php5/apache2/php.ini

... and make these changes:

- ;date.timezone =
+ date.timezone = Australia/Sydney

# change this line, otherwise get errors about assigning a global using a session value.
# ("PHP versions 4.2.3 and lower have an undocumented feature/bug that allows you to initialize
# a session variable in the global scope, albeit register_globals is disabled")
- session.bug_compat_warn = 1
+ session.bug_compat_warn = Off

# hide PHP in the headers
- expose_php = On
+ expose_php = Off

- max_execution_time = 30
+ max_execution_time = 300 ; Equals 5 mins

- memory_limit = 16M
+ memory_limit = 32M

- upload_max_filesize = 2M
+ upload_max_filesize = 10M

- allow_url_fopen = On
+ allow_url_fopen = 0

Then need to restart apache for changes to take effect:

/etc/init.d/apache2 force-reload

Then soft-link the command line php.ini to the apache php.ini, so that they can have a shared configuration:

# diff -u --ignore-all-space /etc/php5/cli/php.ini /etc/php5/apache2/php.ini
mv /etc/php5/cli/php.ini /etc/php5/cli/php.ini-orig
ln -s /etc/php5/apache2/php.ini /etc/php5/cli/php.ini
ls -al /etc/php5/cli/php.ini
