How to close a connection early with PHP?
To close a connection early with PHP, we call ob_end_flush and flush.

header("Connection: close");
ignore_user_abort(true);
ob_start();
echo "Text the user will see";
$size = ob_get_length();
header("Content-Length: $size");
ob_end_flush();
flush();
sleep(30);
echo "Text user will never see";
to call ob_end_flush and flush together to end the TCP connection without ending the PHP script.
Then we run sleep(30); after the connection has ended.
