Well, PHP doesn't change what is written outside <?php ?> (*) so hiding "random" bytes (PHP doesn't know what these bytes mean, PHP only knows collections of bytes as strings with no further logic) might easily break expectations and cause problems which are harder to trace down than a "headers already sent" error which is relatively verbose. johannes *) Yes there is one behavior which might be seen as an exception: If ?> is directly followed by a new line the new line is dropped, but then the new line can be seen part of the ?>. Example: a<?php ?> b Prints ab without line break. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
