I have the following snippet in my file:

      if ($PATH_INFO == "") { $PATH_INFO = "/"; }
      echo "PATH_INFO: $PATH_INFO<br>\n";
      // All we want is the fist element, call it $section
      list($section) = explode('/', substr($PATH_INFO,1));
      if (is_int($section)) {
        echo "section: $section<br>\n";
      } else {
        echo "Invalid section (NON_INT: $section)<br>\n";

    Um, why does it fail when I hit the script with any INT?

    For example: /script/1 fails.  Is $section not an INT when parsed?
