    Problem with getenv

    When I run the following code, I get "Undefined variable: localPath"
    error. I do not understand why? It seems simple enough...but I am new
    to PHP so any help is appreciated.

    I am running PHP 5.2.5 on an XAMPP installation on Win XP/Pro.

    $localpath=gete nv('SCRIPT_NAME ');
    $absolutepath=r ealpath($localP ath);
    // a fix for Windows slashes
    $absolutepath=s tr_replace("\\" ,"/",$absolutepath );
    $docroot=substr ($absolutepath, 0,strpos($absol utepath,$localp ath));


    TIA,
    John

      Because "localpath" is not the same as "localPath" .

      Look carefully and you will see the difference.

          Hi Captain,
          I am very embarrased. Case sensitivity is an ongoing battle for me
          since I come from the VB.Net world. Also, the script I copied from a
          web blog has an error in it (just in case anyone is looking at the
          functionality of this, which is to get the document root regardless of
          Apache or IIS as the server). The author forgot the call to basename
          when getting the absolute path. So here is what works:

          $localpath = getenv('SCRIPT_ NAME');
          $absolutepath = realpath(BASENA ME($localpath)) ;
          // a fix for Windows slashes
          $absolutepath = str_replace("\\ ","/",$absolutepath );
          $docroot = substr($absolut epath,0,strpos( $absolutepath,$ localpath));

          Thanks again for the speedy response. This group is fantastic and as a
          newbie, I sincerely appreciate everyone's efforts.

          John
