PHP 5.5 seems to be the default across new Linux distributions. I'd like SWIG 3 to be ready for this. 

Having run the tests, it looks like there is one simple problem in the pointer example:

Fatal error: Call-time pass-by-reference has been removed in /home/william/swig/github/swig/Examples/php/pointer/runme.php on line 18

What would the new calling syntax be? Probably the example can simply be fixed?

The only other issue I can see is the director_basic test seg faults. Does anyone have the time to analyse it and discuss fixes required?
