    set values once

    let say that i want to allow someone (the site admin maybe) to chose
    certain configuration values, for instance

    * number of products per page
    * picture widht
    * back color
    ....
    ....

    Right now, i just have all those info in a php page, so it can't be
    modified
    $number of products_per_pa ge = 20;
    $picture_widht = 2;
    $back_color = #FFFFFF;

    I could keep this info in the database, but i should read it every time
    a page is rendered... (open connection, query, close conn)

    What would be the best way to do what i'm need? Is there any chance to
    "read once, keep value for ever" ?

    regards - jm

      //jm,

      //I would use sessions or cookies... or you could turn on globals but i
      wouldn't recommend this...

      //example:

      //////////////////////
      //(index.php)
      ///////////////////////
      session_start() ;
      $back_color = #FFFFFF;
      $_SESSION['back_color'] = $back_color;

      //////////////////////
      //(nextPage.php)
      ///////////////////////
      session_start() ;
      <body bgcolor='<? echo $_SESSION['back_color']; ?>'>


      // I hope this helps
      // from,
      //

          But this is mainly what i'm doing right now. Note that #FFFFFF is
          "static" and can't be changed without have access to .php file...

          I should try to see how products like os_commerce or the like solve
          this kind of things...

              right... you want to story users info so that when they log back in
              their settings are kept... use a database for this and query as soon as
              they login. then use my examples to display his or her values.

                  So put it in a file then (although it's not *that* much of an overhead using
                  the DB):

                  file_put_conten ts($config_file , serialize($opti ons));

                  and

                  $options=unseri alize(file_get_ contents($confi g_file));

                  C.
