Details:

Each (gs) Grid-Service has it's own editable php.ini. This makes it possible for administrators to change php values independent of our default php values.

As a courtesy we have provided a sample php.ini file in:

/home/#####/etc/php.ini.sample

where '#####' is substituted by your actual site number. You can edit this file via the File Manager, FTP, or SSH.

From the File Manager:

• Login to the AccountCenter and then your WebControl for your (gs) at (Domains > domain.com.
• Click File Manager.
• Click the folder "etc"
• Edit the file "php.ini.sample"

By changing the filename from "php.ini.sample" to "php.ini" you will be making your changes live.

You may un-comment specific lines in order to change your php environment by deleting the ';' at the beginning of any lines. Below are some common examples:

To turn on register_globals: uncomment ; register_globals = true

To increase the POST size: uncomment ; post_max_size = 20M

To increase php execution time: uncomment ; max_execution_time = 300

You can change other variables as well by adding additional lines to your php.ini. Some examples are:

upload_max_filesize = 20M

include_path = (.:/usr/local/php-4.x.x-x/share/pear/:/path/to/new/includes)

safe_mode = on ; (default is off for your domains)

disable_functions = mail ; Disables use of php mail function

FAQs

Do I need to restart my service for the changes to take effect?

No, in fact there is no way or need for customers to restart the (gs) Grid-Service. Any changes you make within your php.ini will be effective immediately.

Is there any way to use a different php.ini in each domain/folder on the (gs)? 

Not with a php.ini. The php.ini is designed to set global settings for your account. You can make changes on a per domain basis via a .htaccess file. More info on this can be found at http://www.askapache.com/htaccess/php-htaccess-tips-and-tricks.html
