To use PHP 5.5 from MacPorts Apache 2, install the php55-apache2handler port.

Not at this time. Would it really be useful or desired for "port select" 
changed this? Some existing discussion on this is here:

https://trac.macports.org/ticket/45999

For now, edit your httpd.conf to point to the specific PHP version of the PHP 
Apache 2 handler that you want to use.

No, you don't need to do that / it's not possible to do that. Any PHP extension 
that you've installed for a particular version of MacPorts PHP will be 
available to all MacPorts PHP SAPIs that you install for that PHP version.

PHP is offered in several different "SAPI"s: a command line version, a FastCGI 
version, an FastCGI Process Manager (FPM) version, and an Apache 2 module. Each 
of these is in and of itself a complete PHP environment, just tailored to be 
used in a specific way. Install the one(s) you want to use. For a given PHP 
version, all of these SAPIs use the same set of versioned PHP modules.
