Why is it that

<?php

include_once('FirePHPCore/fb.php');
ob_start();
$firephpoptions = array('maxObjectDepth' => 10,'maxArrayDepth' => 20,'useNativeJsonEncode' => FALSE,'includeLineNumbers' => TRUE);
FB::setOptions($firephpoptions);
FB::setEnabled(TRUE); // Disable on production server - otherwise it's a security risk
FB::info("Firebug ready to go!");
?>

works but

<?php

ob_start();
$firephpoptions = array('maxObjectDepth' => 10,'maxArrayDepth' => 20,'useNativeJsonEncode' => FALSE,'includeLineNumbers' => TRUE);
FB::setOptions($firephpoptions);
FB::setEnabled(TRUE); // Disable on production server - otherwise it's a security risk
FB::info("Firebug ready to go!");
?>
</body>
</html>

throws the error...

PHP Fatal error: Uncaught exception 'Exception' with message 'Headers already sent in /Applications/MAMP/htdocs/rssscraper/svn/index copy.php on line 9. Cannot send log data to FirePHP. You must have Output Buffering enabled via ob_start() or output_buffering ini directive.' in /Applications/MAMP/includes/FirePHPCore/FirePHP.class.php:950

Try this:

<?php
  include_once('FirePHPCore/fb.php');
  ob_start();
  $firephpoptions = array('maxObjectDepth' => 10,'maxArrayDepth' => 20,'useNativeJsonEncode' => FALSE,'includeLineNumbers' => TRUE);
  FB::setOptions($firephpoptions);
  FB::setEnabled(TRUE); // Disable on production server - otherwise it's a security risk
?>

        </body>
</html>

That does work, thank you Christoph, however I'm still wondering why it behaves that way? Why does the php need to be first and not embedded in HTML?

It's not a complaint, just a need to learn something from this.

Thanks again Christoph.

It has to be done this way because if the HTML appears before output buffering is started with ob_start(), the code appearing before ob_start() will be sent to the browser right away, and once data has been sent to the browser, firebug cannot send data in the headers. If you at least turn on output buffering, you can then throw in html code before your actual FirePHP call, because that html will be buffered
