I actually must say we have a special kind of output buffering that saves all the content in an array like structure and outputs all content at the end. This way we managed to have our coders work in a rather C/C++ like way, where they can modify the rendered content anywhere in a script. The fact that the error gets detected twice is maybe a weirdness in our output handler, but as you guys already said, this should be detected actually as a parse error. About the editor, it's weird. We use Eclipse Europa (PDT Tools), because they integrate superb with our SVN2WEB development schema (instant web publish, SVN backup) and the error isn't highlighted in Eclipse. The manual tells nothing about such a thing. It's actually a weird glitch. Why: because if a PHP project decides it wants some weird control over the output buffer, like we do right here with our "delay output until the script ends" ideology, chances for such a typo to cause headaches is great. I can see projects rendered useless for a time, until the code is scanned for such a weirdness. All in all, thanks guys for the time you took testing this. It seems I must revise our output-handler, and do something to our Eclipse PDT set-up so it can detect this as an error. -----Original Message----- From: Thijs Lensselink [mailto:dev@xxxxxxxx] Sent: Saturday, August 30, 2008 3:25 PM Cc: php-general@xxxxxxxxxxxxx Subject: Re: Is this a bug?

I don't think it should be valid outside a string. But PHP seems to see this different. The only reason i could think of. Is that the \ somehow is a registered symbol. So it throws a non fatal E_COMPILE_ERROR. Could be a bug. That's for the guys on internals to decide. I'd also expect a parse error. With output buffering enabled i still get the same warning on every request. > >> >> >> > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
