John Walsh's Blog:
PHP Benchmark - For vs While
March 26, 2007 @ 15:19:23

John Walsh filled us in on a new set of benchmarks he worked up comparing two of the standard looping structures in PHP - for versus while.

People always ask me what statement is faster, so I've gone ahead and created a benchmark test using Apache's AB Benchmarking tool. There's no reason not to use For either, you can use it with any while statement but While in some cases mean's less lines, but i prefer speed than less lines of code.

He created some simple scripts to perform the tests and ran them through the AB benchmarker to come up with his results - with while just barely edging out the for loop by one millisecond.
