    PHP + cURL + session id

    Hello all,
    I have simple PHP application that on one page strarts session and
    write some information to it. On another page program tryes to fetch
    information from a third page using cURL. On that third page program
    needs to retrive information that were written to the session and use
    them. Problem is that when I call the third page and call
    session_start() it starts a new session where there are no infromation
    I need. Code below.

    <code>
    <?
    /**
    * file: t1.php
    */
    session_start() ;
    $_SESSION['user'] = 'lukas';
    echo '<html>
    <body>
    <a href="t2.php">' .$_SESSION['user'].' 2 >> </a>
    </body>
    </html>';
    ?>

    <?
    /**
    * file: t2.php
    */
    session_start() ;
    $_SESSION['user'].=" add some info.";
    $url="http://www.myserver.co m/t3.php"
    $ch = curl_init();
    curl_setopt($ch , CURLOPT_URL, $url);
    curl_setopt($ch , CURLOPT_TIMEOUT , 2);
    //curl_setopt($ch , CURLOPT_COOKIE,
    session_name(). "=".session_id( ).";"); //when I uncomment that line
    operation times out
    $output = curl_exec($ch);
    echo "output: ".$output." <br/>";
    echo "error no: ".curl_errno($c h)."<br/>";
    echo "error: ".curl_error($c h)."<br/>";
    curl_close($ch) ;
    ?>

    <?
    /**
    * file: t3.php
    */
    session_start() ;
    if(isset($_SESS ION['user']))
    echo "yeah<br/>";
    else
    echo "nope<br/>";
    ?>
    </code>

      Re: PHP + cURL + session id

      Problem is in session identification.
      When you start a session, it gets unique identifier, which is passed to
      your browser (in cookie or, if cookies are off, in GET parameter). Value
      stored in the session is saved on the server and next time you call
      session_start, PHP finds it on the server according to this identifier.

      For the third script the calling client is not your browser, but cURL
      client on the server. However, it doesn't know the session identifier,
      so the session is empty.

      What you need is to pass session identifier to the URL called by cURL in
      second script as a GET parameter.

          Thanks for your reply.
          I did what you had suggested and still no luck. I appended
          session_name(). "=".session_id( ) to the URL I wanted to fetch and the
          results were the same as when I set this line in the second script:
          curl_setopt($ch , CURLOPT_COOKIE, session_name(). "=".session_id( ).";");
          "Operation timed out with 0 out of -1 bytes received". If you have any
          other suggestions let me know.

          Thanks.

          Best regards,
          Luke
