title: Prevent output buffering with PHP and Apache
body: <p>I have a PHP script which sends a large number of records, and I want to flush each record as soon as it is available: the client is able to process each record as it arrives, it does not need to wait for the entire response. I realize it takes slightly longer for the entire transfer because it needs to be sent in multiple packets, but it still allows the client to start working sooner.</p>
  
  <p>I've tried all the different <code>flush()</code> and <code>ob_flush()</code> functions but nothing seems to help get the data actually sent over the line before the page is finished. I've confirmed that it is not the web browser because I've tested it using telnet.</p>
