Dealing with headers already sent

amrigo

I have a html file and at the middle i need to have these lines:

header("Content-Type: text/xml");
readfile("../file.xml");

So i get the header already sent message :
Cannot add header information - headers already sent by (output started at //path//

How can i workaround this ?

Thank´s in advance

Look into output buffering. And for everyone's sake, please try to contain the number of threads you create per day. This is at least the third one I've seen today, two of which were dealing with the same issue.

[man]ob_start[/man]

This forum is here to ask questions, but there is no need to repeat questions across multiple threads.

There is also no reason you cannot ask multiple questions in a given thread. Just a tip...

ok!

I think the correct terminology to be used here is UTFSB 😃

i need to read an xml file and i do not have output buffering functions compiled with php as i get :
Call to undefined function: ob_clean()

i am using :
header("Content-Type: text/xml");
readfile("the file.xml");
inside another html file

is there any other way i can skip the :

Cannot add header information - headers already sent by (output started at /path/to/

problem?

Best regards

You must have an older version of PHP then - [man]ob_clean[/man] been there since 4.2. The manual page for it suggests you also look at [man]ob_end_clean[/man] as well (gee, ain't the manual useful when you use it?).

But a better solution all around would be to give a bit more thought to how your code is structured - and don't send any output to the client before you've sent the necessary headers.

But here's a question: why are you wanting to send a text/xml header anyway if you're sending an HTML page? Are you wanting to display XML inside an HTML page in some way somehow?

I need some contents of the website to be edited by the client
(1 or 2 times per year) and i dont want to put it on database.

So i write xml instead of txt as i have php4.1.1 i use readfile to read the xml file .

Also i have a main.php file with topbar and footbar and i just includes the asked page inside this included page may come some page that read the content from xml formatted with xsl with works in some servers but the one i must to work have a old php version.

I already got the solution wich is not to use xsl to format the xml and use a hardcoded php parser to read the xml so my problems disappear i was just wondering another way to use xsl!?
