Modified files:
/phpdoc/en/reference/http/functions headers-sent.xml
Log:
This page incorrectly stated that headers_sent() will
return true if the headers were not sent, which is the
opposite of how this function behaves. Correcting this.
Also made the example work standalone, and reworded the
explanation of the new file and line parameters, so it
now says that the value is put into those variables and
not returned...

You can't add any more header lines using the <function>header</function>
function once the header block has already been sent. Using this function
