Calling ob_flush() and flush(), yet browser doesn't show any output until script finishes
Hey man I was also got stuck in this problem and finally got the correct solutionhere it is for you
you have to add content type for your page you can do that by two ways 1. using html tag
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">Ex.
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Wp Migration</title></head><body><?php for($i=0;$i<70;$i++){echo 'printing...<br>';ob_flush();flush();sleep(3);}?></body></html>using php header function
<?php header( 'Content-type: text/html; charset=utf-8' ); ?>
Ex.
<?php header( 'Content-type: text/html; charset=utf-8' );for($i=0;$i<70;$i++){echo 'printing...<br>';ob_flush();flush();sleep(3);}?>All the best
Some browsers need to receive at least 256 characters before they start to render. Have you already tried to stuff more output like:
echo str_repeat(' ', 50) . "$i<br />\n";EDIT:
Under Apache/2.2.11 (Win32) DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.8i PHP/5.2.9 I was able to reproduce the problem of the OP by setting
zlib.output_compression = OnTurning it off again by
zlib.output_compression = Offmade the script work as wanted.
Try removing the call to ob_start() on your first line : there is no need for you to enable output buffering -- and it probably causes troubles, here.
I've tested your code :
- If
ob_start()is called on the first line, I only see the output when the script finishes, after 10 seconds - If I remove that call to
ob_start(), then, I see one line of output every second, as soon as it's displayed on the standard output.
