The benefit to using quotes is that it's the right thing to do, unless you're looking for constants instead of strings. Sometimes a quick R of the first few chapters in TFM beats a benchmark. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That is because the one without the quotes, php first checks to see if a constant is defined with that name, if not then the literal value will be used.

[PHP] Associative Array Benchmarking
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 50 times in 4.4331 seconds. Function assocArrayWithoutQuotes() ran 50 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.
