DirectAdmin does not upgrade php for you (unless they have some special arrangements), but they have provided the customapache tool allowing easy upgrading of php
Oh, customapache can also be used to upgrade PHP as well as Apache? What are the commands for doing this as I have not seen them anywhere. I have only seen the commands to upgrade Apache. Thanks.
Typing "./build" will show you a list of all available programs to compile. For example if you needed to compile zend you would do "./build zend" or if you wantd to do everything (except zend) you would use "./build all" and so on.
./build being run in /usr/local/directadmin/customapache/
