If you'd only seen PHP a few times, applying for a job in it may not be the brightest idea. ( If you have enough experience you could probably do a reasonably good bluff and learn-as-you-go, but not recommended ).

I'd suggest something like rating your experience with various things, either by giving it a points/stars rating system, or by having categories such as "Proficient In:" and "Some Experience with:" and "Have also used:" , possibly with examples of where and how you used it.
