    Can Constants Be Used Inside Header()?

    i have something similar to this:

    <?php
    header("Locatio n: http://mysite.com/destination.php ");
    ?>

    i would like to replace "mysite.com/destination.php " with a constant.

    for example, with a constant DESTINATION defined as
    "mysite.com/destination.php ".

    can this be done?

    if so, how?

    tia...

      You mean like this?

      define('DESTINA TION', 'http://mysite.com/destination.php ');
      ....
      header('Locatio n: ' . DESTINATION);

          this doesn't work for me.

          this is copy and paste... (except for mysite.com).

          define("ENTER_C USTOMER_URL", "http://mysite.com/index.php");
          header('Locatio n: ' . ENTER_CUSTOMER_ URL);

              So what actually happens when you try it?

              To debug, try doing this instead:

              define("ENTER_C USTOMER_URL", "http://mysite.com/index.php");
              print('Location : ' . ENTER_CUSTOMER_ URL);

              This way you get to see the output.

                  How does it "not work"? Any error messages?

                  Looks OK and works here (but please use www.example.com/org for example
                  URLs, these domains are reserved for that purpose).

                      Do you have exit(); after the header call? If not and you are running
                      any code after the call, this could cause unwanted results.

                          Constants aren't any sort of mystery. Try:

                          echo 'Location: ' . ENTER_CUSTOMER_ URL;

                          and you'll see the exact argument you are passing to header(). BTW, perhaps
                          you are missing an exit() somewhere after the redirection.

                              chris, thanks for the tip. the value printed is the ocrrect url.

                              i think the problem is how header handles variables within the quotes
                              used to pass the string to the header function.

                              there must be some kind of methodology for handling this - i'll search
                              the net some and get back.
