    Sharing session variables

    How can I share session registered variables between different processes?
    Here is my problem:
    File 1:
    -----------------------------------------------------------------------
    <?php
    session_start() ;
    $var1="This should";
    $var2="be displayed";
    $_SESSION[ 'var1' ]=$var1;
    $_SESSION[ 'var2' ]=$var2;
    if (session_is_reg istered('var1') ) {
    print "Var1 is registered<br>" ;
    }
    if (session_is_reg istered('var2') ) {
    print "Var2 is registered<br>" ;
    }
    print "<A HREF=/work/test2.php>Secon d File</A>";
    ?>


    File 2:
    -----------------------------------------------------------------------
    <?php
    if (session_is_reg istered('var1') ) {
    print "test2:Var1 is registered<br>" ;
    }
    if (session_is_reg istered('var2') ) {
    print "test2:Var2 is registered<br>" ;
    }

    $var1=$_SESSION[ 'var1' ];
    $var2=$_SESSION[ 'var2' ];
    print "$var1 $var2 <br>";
    ?>


    In file test2.php neither variable is reported as a session registered
    variable and nothing is displayed. File /tmp/sess* has the correct
    contents:
    var1|s:11:"This should";var2|s: 12:"be displayed";

    How can I establish real global variables, ones which will
    be visible in both files? I thought that httpd was supposed
    to read the sessxxxxx file, depending on the cookie received from
    the browser and establish those global variables.
    I apologize if it is a beginer question, but I was unable to
    answer it either through the O'Reilly book or PHP online literature.
    I'm at the verge of re-installing PHP 4.3.36 with shmop module enabled.

      make sure you add:
      session_start() ;
      and the top of each page that you want to access the variables in.

          Thanks a lot. That was it.

              Be sure to session_start() the session in test2.php. The session_start()
              function is a bit misnamed. You use it to start a new session but you also
              use it to continue an old one.

              PHP: session_start - Manual
              http://us3.php.net/manual/en/function.session-start.php
              Start new or resume existing session
