Hi, actually, echo with commas is faster than any other form of printing, although it is highly unlikely to be the bottleneck in any application. However, one never knows. A few years back I moved a large application from "double quotes" to 'single quotes' and there was a noticeable difference in speed (seconds) to the end user even without a profiler. This was early PHP on a slow server though :) Greg
