I want to show on the browser, ccc2 (example) every 1 second, but it
shows all the text when the for stops... any ideea?
i tried all the examples from php.net, all the examples on the net,
bot no succes.
cheers,
PHP is a server side scripting language, so the information would not be
sent to the browser( aka client) until the server side script has
completed its execution.

That is incorrect. There is nothing stopping a PHP script from doing
exactly what he says, and being a server-side script doesn't imply that
the data will be buffered.
I suggest that both of you examine the contents of
http://www.php.net/manual/en/function.flush.php for more information on
obstacles to getting data to the client as it is generated.
As an unrelated note, there is no point in using print for some things
and echo for others. For your uses, you might as well just use echo
for everything.

ob_flush() only makes sense if you have ob_start() somewhere, or if
output_buffering is enabled in php.ini
flush(); and sleep(1); are all you should need...
At least from PHP standpoint.
But there are many other players outside the control of PHP...
Apache could be buffering output.
TCP could be buffering output.
Your browser will NOT render some parts of some elements until the
tags are all closed -- If you are inside a TABLE, for instance, expect
not to see things happening in real-time.

This is just plain incorrect. While buffering within various pieces of software MAY alter the timing, data IS output from PHP as it runs, not only after execution is completed. If you pump ENOUGH data out, and then sleep(10) and then pump ENOUGH more data out, you WILL see the data in parallel with script execution. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
