 * When working in a pure PHP file (e.g. not an HTML template), omit any trailing  tags. These tags often cause issues with trailing white-space and "headers already sent" error messages (cf. 17642 and http://news.php.net/php.general/280796). It is conventional in version control for files to have a new line at end-of-file (which editors may add automatically), which would then trigger this error.
