    unserialize

    I finally got serialize to work but now I cannot get unserialize to work. Here is my code.


    $settings = serialize($sett ings_array);
    echo "<INPUT TYPE='Hidden' NAME='settings' VALUE='".$setti ngs."'>";


    $settings = $_REQUEST['settings'];
    echo "<P>us=".$setti ngs;
    $settings_array = Array();
    $settings_array = unserialize($se ttings);
    //if($debug) {
    echo "<P> SETTINGS ARRAY <P>";
    print_r($settin gs_array);
    echo "<P>";
    //}


    $settings shows the unserialized data.

    us=a:3:{s:2:\"i d\";s:1:\"0\";s :5:\"fname\";s: 1:\"x\";s:5:\"l name\";s:1:\"x\ ";}

    but nothing is showing up for the array $settings_array when I do a print_r.

    Where have I gone wrong? All help is appreciated. Thanks.

    Mike

      Re: unserialize

      Check your data that comes in $_REQUEST['settings'] it will most likely
      have to be URL decoded to work properly with the unserializer. This
      might work better:
      $settings = rawurldecode($_ REQUEST['settings']);

      Debug outputting with <p> is a bad idea since url encoded characters
      will be interpreted by the browser.

          When I try to unserialize this string I get this error:

          Notice: unserialize(): Error at offset 0 of 78 bytes in C:\tmp\borrame. php
          on line 3

          It sounds like you don't have PHP configured to display notices. Add this
          to top of your code:

          error_reporting (E_ALL);

          Also, apparently you have magic_quotes_gp c on so PHP is adding \ to all
          your quotes, so " becomes \" when you read it. I suggest you edit php.ini
          and set magic off:

          ; Magic quotes for incoming GET/POST/Cookie data.
          magic_quotes_gp c = Off

          ; Magic quotes for runtime-generated data, e.g. data from SQL, from exec(),
          etc.
          magic_quotes_ru ntime = Off

          If you cannot reconfigure your host, then you need further coding. Ask for
          it if you need it.

              Re: unserialize

              Some other apps need magic quotes on. I guess there is no consistency about what is used. Maybe some
              apps are older than others.

              I tried to unserialize with urlrawencode and stripslashes and neither made a difference. I would
              think that would take the slashes out. Is that correct?

              I am open for more ideas. I've never used serialize/unserialize before so this is a learning
              experience for me.

              Thanks.

              Mike

                  Then:

                  if(get_magic_qu otes_gpc()){
                  $foo=stripslash es($_POST['foo']);
                  }


                  And, please believe me, always use this when coding:

                  error_reporting (E_ALL);

                      I was not sure that I could put that inline. Thanks for the tip.
