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. Peter elisabeth theresia wrote:

Elisabeth, It's quite as simple as the session handling. You can split your code into many files or keep it in one single file, the only thing you have to know is that PHP's session_start() function call must be the first thing wrote, no HTML or PHP code before that.

Well, you can turn the things by other way. Put at top of HTML file in the ob_start() function to tell PHP to buffer all output. Change your your index_cobachan by adding $html = ob_get_contens(); ob_end_clean(); Now all the content that would be sent to browser is available at $html string variable. After the includes in your index_cobachan print the contents of $html var. Now do your application logic. THen append the rest of HTML file. Another option is to turn your HTML file into a template and add a special mark to signal template engine to replace some content but this would be another aproach. 2010/8/13 elisabeth theresia <[email protected] <mailto:[email protected]>> Thanks Mr.Sumariva for the advice but, session_start() in the page already embed in Chameleon framework at its folder in \htdocs\common\session the coding at line 509 (that shown error in the page): //start the session session_start(); register_shutdown_function( "session_write_close" ); // set IP if a new session if ( $bNewSession ) $_SESSION["gszRemoteAdd"] = $_SERVER["REMOTE_ADDR"]; /* ============================================================================ * Check IP to see if it is the same * ========================================================================= */ // check if the IP has been set and validate if ( isset( $_SESSION["gszRemoteAdd"] ) && strlen(trim($_SESSION["gszRemoteAdd"])) > 0 ) { // check if IP matches current client if ( trim( $_SESSION["gszRemoteAdd"] ) != trim( $_SERVER["REMOTE_ADDR"] ) ) { // possible security breach void session /* if the session address is the loopback interface then it is * likely that the application was configured to use an external * address but someone is trying to test locally using localhost */ if ($_SESSION['gszRemoteAdd'] != '127.0.0.1') { $bSessionOK = false; } } } else { // possible security breach void session $bSessionOK = false; } // return success or failure and set global so we // know session has been inited. if ($bSessionOK) { $GLOBALS['session_started'] = true; } return $bSessionOK; // end intializeSession() function } function getSessionSavePath() { $szReturn = ini_get("session.save_path")."/sess_".session_id()."/"; $szReturn = str_replace( "\\", "/", $szReturn ); return $szReturn; } Really need advice again Mr. Thanks ------------------------------------------------------------------------ *From:* Cristiano Sumariva <[email protected] <mailto:[email protected]>> *To:* elisabeth theresia <[email protected] <mailto:[email protected]>> *Sent:* Sat, August 14, 2010 8:57:29 AM *Subject:* Re: [mapserver-users] how to disappear Warning: session_start() in the page? You should break your file in 2 files. Put the session_start function at first and add it to the top of your .phtml file. The second file will contain all remaining code. When using session in pages they have to be sent before any other thing. This is a requirement in HTTP protocol. 2010/8/13 elisabeth theresia <[email protected] <mailto:[email protected]>> Hi all, i got message (for preview- i attached the page in attachment-sessionerror2.jpg) : *Warning*: session_start() [function.session-start <http://localhost/appweb/function.session-start>]: Cannot send session cache limiter - headers already sent (output started at I:\ms4w\apps\appweb\htdocs\index_spatialphtml.phtml:6) in *I:\ms4w\apps\appweb\htdocs\common\session\session.php**509* on line i have mapfile and template that already could show in the initialize page named index_cobacham.phtml Then my html + php = index_spatialphtml.phtml i put <?php include ("index_cobacham.phtml")?> above the syntax html.
