Note Submitter: Zoran ---- @Paul You have to remember that PHP interprets strings as zero if used in mathematical expressions (unless they start with a parseable number, i.e. "1234abcd"). So when you try to concatenate "Took:" and $end you get a string which when followed by a minus operator is interpreted as zero. So the result is -$start. Finally, that's interpreted as a string and concatenated with " seconds". To avoid this you can just enclose the math part in parentheses so that the subtraction is given priority: <?echo 'Took:'.($end-$start).' seconds';?>
