update PHP

[Carmel NY]

I am running a FreeBSD 10.2 - p7 machine. I have PHP 5.4 installed . I want
to update it to version 5.6. Would this method work:

portupgrade -o lang/php56 lang/php5

Then:

portupgrade -o lang/php56-extensions lang/php5-extensions

Would I l then need to rebuild everything that depends on PHP or could I just
add the "-r" flag to portupgrade?

These are all of the installed PHP ports:
