bogus, The "one-line" comment styles only comment to the end of the line or the 
current block of PHP code, 
see http://www.php.net/manual/en/language.basic-syntax.comments.php

In my script this is a one line comment style and it does not comment to the end of the line. If it was the case, php would not display the ;' following ?>

But you end the current PHP block with ?>. The parser doesn't care that the code 
in the comment would be valid.

Thank you for your useful comments.

I thought php would have parsed until the end of line, whatever the content is.
When you comment this kind of line, it's not easy to remember
that the ?> will close the php block since it is not clear.
In my code it was a // $content = preg_replace('~<.*?>~','',$content); which generated the problem.
