[Resolved] Problem with echo!

Chris_Evans

Hi there,
I'm having a problem with echo:

<?php
	echo "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>\n";
?>

For some reason, the result is:

<?xml version="1.0" encoding="iso-8859-1"?>\n";
?>

Whereas it should just be:

<?xml version="1.0" encoding="iso-8859-1"?>

What's even more interesting is that when there is code before that echo statement, it doesn't happen...

Any help would be appreciated! It needs to go... I think it's something to do with the last ?> in the statement.

Thanks,

Chris

try this...


echo chr(60).chr(63)."xml version".chr(61)."\"1.0\" encoding".chr(61)."\"iso".chr(45)."8859".chr(45)."1".chr(63).chr(62);

Hope this works 🙂

edit: In your post where <? is, php/apache may think its the beginning of the <?php tag (They usually can both be used (depends on server)) - Also, php is always closed off with ?> tag - so that wont work either 😛

Works brilliantly! Thanks🙂

if you ever have a problem again, visit www.asciitable.com and use the chr() function 🙂

Ok, will do. 🙂 Added to favourites. 😉

Incidentally,

echo chr(60).chr(63)."xml version".chr(61)."\"1.0\" encoding".chr(61)."\"UTF".chr(45)."8".chr(63).chr(62);

seems like overkill if all you want to do is not hang up on the ?> in the string. What's wrong with

echo '<?xml version="1.0" encoding="UTF-8"?'.'>';

?
Or (since I tried to emulate the original problem an didn't get it) upgrading PHP?

On top of that, turning off support for short_open_tags in php.ini (or .htaccess) and using <?php exclusively would mean that the line doesn't need to be echoed at all and can be written as

<?xml version="1.0" encoding="UTF-8"?>

PHP on the server is the latest stable version so that's not the issue.

As I said though - when I echoed out that with no php code before it, it worked fine, but when I had written code before it, it echoed out the ?>.

Well, maybe it had something to do with the code you'd written before it (though I can't think what): my tests (with made-up code before the echo) weren't with the latest stable releases, but with slightly older (sub)versions.

Besides, my point was that that stuff with chr() looked ridiculous.

Chris_Evans

Well, you're right... did look a bit over the top I suppose because it could have just been the last bit that was done. But there we go. 🙂
