lang/php5 port

[Tom Worster]

is there any documentation or a helpful website for how to use ports to
install php5?

i'm used to compiling it with a pretty long configuration command for all
the optional bits i need, e.g. --with-dom --with-dom-xslt --enable-dom
--with-pear --with-gd etc. etc. on and on.

i'm unclear how these options are handled in freebsd ports. is it a matter
of identifying lots of individual ports, one for each of the configuration
command options i'd normally use?
