NYCPHP Meetup

[Marty.Hickey at ogilvy.com]

I don't know if you have seen on http://www.slashdot.org that the lead
article is that Yahoo has switched their backend to PHP. Here's the main
presentation given at PHPCon.

I have one further enhancement to suggest, drawn from a function I use
elsewhere. In the latter case, if the headers have not yet been sent,
you'll want to use PHP to generate a redirect header for you instead
of loading the page and redirecting with javascript. This is basically
what I'm thinking, although I have yet to test it to see if it works
consistently:

--------------------

function REDIRECT ($url)
{
  if (substr($url, 0, 7) != 'http://') {
    if (substr($url, 0, 1) == '/') {
      $url = 'http://'.$_SERVER['HTTP_HOST'].$url;
    } else {
      $url = 'http://'.$_SERVER['HTTP_HOST'].'/'.$url;
    }
  }
  if (!headers_sent()) {
    header('Location: '.$url);
  } else {
    print '<script>';
    print "location.href='".$url."';";
    print '</script>';
  }
}

I got most of the functionality of my session-based jumpback stack
working today. Don't know if that'll help you at all.
