PHP Error Class ‘XsltProcessor’ not found
If you get the following error message in PHP then it means you need to have the XSL extension installed. Obviously the /path/to/file.php will be the actual path and filename of the PHP script the error occured in, and the line number will be the actual line.

I have always used concatenation when writing out multiple strings with echo or print, but recently discovered that echo accepts multiple arguments or parameters, comma separated like a regular function call. This post does some benchmarking to see which is faster: echo with commas, echo with concatenation, or print with concatenation.
