8.12. Flushing Output to the Browser

8.12.3. Discussion

The flush( ) function sends all output that PHP has internally buffered to the web server, but the web server may have internal buffering of its own that delays when the data reaches the browser. Additionally, some browsers don't display data immediately upon receiving it, and some versions of Internet Explorer don't display a page until they've received at least 256 bytes. To force IE to display content, print blank spaces at the beginning of the page:

print str_repeat(' ',300);
print 'Finding identical snowflakes...';
flush();
$sth = $dbh->query(
    'SELECT shape,COUNT(*) AS c FROM snowflakes GROUP BY shape HAVING c > 1');
