session_start(): Cannot send session cache limiter - headers already sent

[lawrence k]

I'm getting this warning:

[15-May-2006 18:11:35] PHP Warning: session_start() : Cannot send
session cache limiter - headers already sent in
/home/httpd/vhosts/monkeyclaus.org/httpdocs/media/audio/pdsIncludes/CommandStartSes sion.php
on line 14


line 14 is this:

session_start() ;


why is that creating a warning?

http://nl2.php.net/manual/en/function.session-start.php

Note: If you are using cookie-based sessions, you must call session_start()
before anything is outputted to the browser.

Comment of header() is also applicable:

http://nl2.php.net/manual/en/function.header.php

Remember that header() must be called before any actual output is sent,
either by normal HTML tags, blank lines in a file, or from PHP. It is a very
common error to read code with include(), or require(), functions, or
another file access function, and have spaces or empty lines that are output
before header() is called. The same problem exists when using a single
PHP/HTML file.

Yes, I know, but the error is pointing to a line that says only this:

session_start() ;

Is that not insane?

It's saying that headers were already sent in CommandStartSes sion.php
on line 14, but line 14 simply calls session_start() .

I mean, what the hell?

Lines in error reporting aren't always correct, sometimes you have to do it
the hard way.
