Although I'm not certain how well known this is, I thought I'd share this
with everyone who might have wondered if there was a benefit to using or not
using quotes when referencing associative arrays.
While benchmarking a few different array sorting options, I had used
in_array and search_array. I noticed that one was more than 30% faster than
the other. On further investigation I realized I had used quotes one one
and not the other.
Benchmark results:
Function assocArrayWithQuotes() ran 500000 times in 4.4331 seconds.
Function assocArrayWithoutQuotes() ran 500000 times in 6.4170 seconds.
The only difference in the two functions is the use of quotes, one with and
the other without.
Flame at will.
