PHP Buffer control question.

[mshen]

I do a sample test for PHP buffer control.I hope "welcome" appear first and after 20 second "successful" appear.

the code is here:

<?php
ob_start();
echo "welcome !!<br>";
ob_flush();
//
sleep(20);
echo "successful";
?>

but it do not work.the two word appear at same time after 20 second.

Please let me know how to use buffer control with PHP.

thanks a lot.

Try it with a flush()

<?php
ob_start();
echo "welcome !!<br>";
ob_flush();
flush();

sleep(20);
echo "successful";
?>
