Note Submitter: ken@positive-edge.com ---- Just as a quick node, if you are trying to explode a string into an array by spaces and tabs, I did some profiling (for a time-intensive application) and the results suggest that doing a $array = preg_split( "/[ \t]+/", $string ); is jsut as fast as doing the explode. I don't mean 'roughly' - I really mean to microsecond. The test conducted were executed over 50,000 times on various strings and the time was nearly identical. Thought this would help people profile their stuff better.
