    HTTP_BROWSER_AGENT on pocketpc

    Hello,

    I am having a problem with a simple script that checks and tells the user
    what browser they are using.

    First of all, the browser string for Internet Exploxer contains the text
    msie and the browser string for a Pocket PC version of internet explorer
    contain msie AND ppc

    The problem is that when browsing my test page using pocket pc the script
    still returns Interent Explorer. My script is below, can anyone tell me
    how to make it determine correctly when accessing via pocket pc? IT works
    ok usign using all the other browsers.

    Thanks,

    td.

      The problem is because $agent contains MSIE, the first IF statement citeria
      is being met. You are ELSE IF'ing the rest of the way down the script.
      Because the first IF statement was met, it won't run anymore IF's. Therefore
      I recommend you remove the ELSE's and just run independant IF's.

          Cheers.

          I see what you mean but the browser string for IE also contains the word
          Mozilla and that doesn't trip up.

              That's because you aren't matching for "Mozilla". What G-man means, is that
              you should check for powerpc before IE or make the check for IE less
              general:

              // check to see if running ie
              if (preg_match("/MSIE/i", "$agent") && !preg_match("/PPC/i", "$agent")) {
              $result = "You are using Microsoft Internet Explorer.";
              }

                  Coming to think of it, this will also match Opera in MSIE spoofing mode...

                  The following might work out better (emphasis on "might", because browser
                  detection based upon the user agent string is always error prone):

                  if (preg_match("/MSIE/i", $agent) &&
                  !preg_match("/PPC/i", $agent) &&
                  !preg_match("/Opera/i", $agent)) {
                  $result = "You are using Microsoft Internet Explorer.";
                  }
