To the skeptics of isset() performance : I tried to bench the 3 methods in various usecases (varying
the array size, keys and content) and couldn't get anything more impressive than a 2x factor.
But :
* In the real-life project which led me to these considerations, the difference is dramatic : 160
seconds vs 0.21 second (a factor of 760 !).
* I've never witnessed array_key_exists() being faster than isset().
