No, Wi-ki is autotext.
The problem looks like the format; when you're in the editor the stock island looks like:
/* PHP CODE HERE, IF NECESSARY */
/* DO NOT CHANGE THE LINE BELOW */
$body = <<<EOF
EOF;
/* DO NOT CHANGE THE LINE ABOVE */
Yours has significant data after "EOF;" (possibly someone tried editing its file directly, or copied data elsewhere), just update the editor screen with he proper data and you should be fine.
