<p>The PHP closing tag on a PHP document <strong>?&gt;</strong> is optional to the PHP
parser. However, if used, any whitespace following the closing tag,
whether introduced by the developer, user, or an FTP application, can
cause unwanted output, PHP errors, or if the latter are suppressed,
blank pages. For this reason, all PHP files MUST OMIT the PHP closing
tag and end with a single empty line instead.</p>
