php got stomped on in shootout, but shouldn't have...

Howdy. So I was checking out Perl, Ruby, and Java's performance specs on a language shootout, and PHP got stomped on. It was safely sitting at the bottom of the list (check out the score card page). http://www.bagley.org/~doug/shootout/ The good news is, the reason it got stomped on wasn't because of the language, it was because it wasn't represented. So what's the deal here? The only test that PHP was enrolled in was the Ackermann's Function. How could 25 other languages (some I'd never heard of before), have better community support than the beast that is PHP? I'd really like to know how well PHP would stack up compared to these other languages (esp Java) if well represented. Hacking in C (grudgingly), Sean PS What really happened was I just had PHP nuked as a viable language for a contract job I was doing (now doing it in C) because the CTO came back and referenced PHP's performance on this page. The CTO's bright, but an old stodgy UNIX/C programmer that wouldn't give. -- Sean Chittenden
