Why is there a php4 variant but not a php5 variant?

Enabling php4 by default would cause all swig users to have to  
install php4. php4 is pretty much obsolete. The last normal release  
of php4 was made 2008-01-03 and after 2008-08-08 there will be no  
more releases of php4 at all. php5 is the current version. php5 and  
php4 cannot be installed at the same time (with the way the ports are  
set up currently).
