php script appearance in the time

[lionel]

Hello,

This is a simple script I test in a browser (firefox & opera) :

echo "test 1<br />" ;
sleep(3);
echo "test 2<br />" ;

I expected to see "test 1" appearing first and then "test 2" 3 sec after.
Still, I got "test 1" & "test 2" appearing "in one shot" after 3 seconds.
How can I get what I expected (I precised in a browser because there's no pb
in a command line execution) ?

Thanks in advance,

Lionel

Try this

echo "test 1<br />" ;
ob_flush();
flush();
sleep(3);
echo "test 2<br />" ;

It nearly works, I got a notice message. Adding "on_start() ;" at the
beginning makes it disappear.
Thank you.

You can't do it reliably.

You can control what your code does. You can even control the PHP
buffering. But you can't control buffering in the web server, which may
delay the output until the buffer fills or the entire page is sent. You
also cannot control the browser, which may delay displaying the data
until the entire page is received.

You can flush buffers and get it to work much of the time. But not
necessarily all the time.

Thanks for this precision.
