Set the version of PHP to run in some directory
If more than one version of PHP is installed on your system and either CGI
or fCGId is used to run PHP scripts in some virtual server, it can be configured
to run a different PHP version on a per-directory basis. This is most useful
when running PHP applications that only support specific versions, like an
old script that only runs under version 4.
To set a PHP directory, the C<--domain> flag must be used to specify the
directory, C<--dir> to set the path (like C<horde> or C</home/domain/public_html/horde>),
and C<--version> to set the version number. At the time of writing, only
versions 4 and 5 are supported.
