=head1 modify-php-ini.pl
Changes PHP variables for some or all domains.
This command can be used to change the value of a PHP configuration variable
(set in the php.ini file and Apache configuration) for one or many virtual
servers at once. The servers to update can be selected with the C<--domain> or
C<--user> flags, or you can choose to modify them all with the C<--all-domains>
option.
If your system supports multiple PHP versions, you can limit the changes
to the config for a specific version with the C<--php-version> flag folowed
by a number, like 4 or 5.
The variables to change are set with the C<--ini-name> flag, which can be
given multiple times to change more than one variable. The new values are
set either with the C<--ini-value> flag (followed by a number or string),
or the C<--no-ini-value> flag to completely remove a setting.
