Re: header & headers_sent BUG

Added to this, your later header replaces the earlier one of the same type, unless you specify false to the second parameter of header() function. More in the manual. Ford, Mike [LSS] wrote:

I was wondering if someone may be able to explain why the following code will not work... I have been scratching my head for a few hours now and I am stumped. <?php header("Location: http://someplace.com");

At this point, you have specified that you want the header "Location: http://someplace.com" to be sent when headers are sent -- but headers are not sent until you output some actual content to your page. So...

if( ! headers_sent())

... headers haven't been sent yet, so this test always triggers, so...

    header("Location: http://somplaceelse.com");

... this call always executes, specifying that, actually, you want *this* Location header to be sent when headers are sent, not the one specified before. I haven't the faintest idea what you might be trying to achieve here, but I think you need to rethink the logic of how you choose which redirect to use. Cheers!
