PHP Function Speed Benchmarking


Monday, May 22, 2006; 03:26 AM

A comparison between the speeds of various PHP5 functions was posted at http://byster.net/?page_id=48 . The benchmarking list compares the execution speeds of PHP functions that produce identical results. There are ten examples for PHP5 and, additionally, ten more examples for PHP4.  

The list compares (in microseconds, or thousands of a second) how different functions perform tasks like parsing and finding text, or generating random numbers. While, admitedly, there are more significant bottlenecks to web application speeds than subtle differences in PHP performance, the benchmarking list is an interesting read for PHP coders.
