Re: Odd is_int() behaviour

This is expected behaviour. Ashley M. Kirchner wrote:

    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));

explode() is string function and returns array of strings. Therefore, type is integer.

      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?

'1' is not integer, but string. 1 is integer. BTW, all user inputs(POST/GET/etc) are string. -- Yasuo Ohgaki
