[mapserver-users] how to disappear Warning: session_start() in the page?

Thu Aug 19 19:21:56 PDT 2010

Im not familiar with the code you are talking about, but i can tell you briefly when this errro occurs: an http response consists of two parts a header and the body. Attempts to write a http header when one has already been written and the body started will cause an error. A common cause of this (other than just plain writing a header in the wrong place) is that one of the libs in your package has stray whitespace in it, eg even a single space char after the closing ?> tag

Where to look in your case?

   "I:\ms4w\apps\appweb\htdocs\common\session\session.php on line 509 is
    trying to send a session control header."

Theres where the header is attempted.

   "headers already sent (output started at
    I:\ms4w\apps\appweb\htdocs\index_spatialphtml.phtml:6)"

Theres were the unexpected http body chars were found. Thats where id be looking.

If its not whitespace, then you need a programmer. Good luck.
