Re: [PHP] no newline after ? in the resulting HTML
Really I think it would be loosing time documenting that you can put a new line after ?! I mean it's obvious that what's outside php tags will be printed rite?

If you put a space and a newline after that space, both will not be deleted. That is all. P.S. could you not top-post, please.

If you want the newline, you should do: ?php echo pHello World/p\n; ? As for WHY the [newline] after ? is ignored, it just turns out that there are more times when you want it that way than the other, *AND* it's trivial to insert a \n into your output, *AND* it would be very hard to come up with a way to make the newline NOT appear if the default was to have it appear, *AND* a *TON* of things would go wrong if the extra newline appeared where you don't want it, but it's pretty unimportant if a newline is missing at that point in the tutorial and in most real-world cases (IE, HTML output) where you have ?[newline] It's not a bug ; It's a feature -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] no newline after ? in the resulting HTML
Why there is no newline afer pHello World/p ? Is it a PHP bug or the tutorial should be updated? The tutorial is fine. The sample code mentioned: html head titlePHP Test/title /head body ?php echo 'pHello World/p'; ? /body /html Contains a line break after the pHello World/p is echoed . Check your code, if you don't have that line break, PHP is not going to create it for you. Brady -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Check your code, if you don't have that line break, PHP is not going to create it for you. That's actually not true. A line break after a closing ? is ignored. This is to make it possible to have something like this: ?php /* do something */ ? html ... /html And have that opening html tag be on the first line of the file. Another reason is for include files. If you include a file that ends with ?newline then you normally don't want that newline. Having a newline output for each file you include doesn't make much sense. So yes, technically the tutorial is wrong. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Put in an extra newline after ? if you need them, or put a \n at the end of the last echo inside the PHP block. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I discuss this here: http://shiflett.org/archive/151 It's a feature of PHP that has some advantages and disadvantages, and it's not likely to change (consistency has merit, regardless of what you think of the behavior).
