delay function

netfrugal

I've been looking, and I thought I'd ask about delaying execution of php scripts on one page.

I've tried

 <? sleep(10); ?>

example:

<?php

// current time
echo date('h:i:s') . "\n";

// sleep for 10 seconds
sleep(10);

// wake up !
echo date('h:i:s') . "\n";

?>

But it seems to delay the entire page, whereas, I'd like to delay the second wake up alert for ten seconds, while the first shows before the sleep function.

Is there a function for this?

Will not work on all web-servers, as some will buffer all script content until the script is done:

<?php

// current time
echo date('h:i:s') . "\n";

// force buffer flush:
flush();

// sleep for 10 seconds
sleep(10);

// wake up !
echo date('h:i:s') . "\n";

?>

Not only does this depend on the webserver, but also the browser; IIRC, IE has some issue with not rendering content on an incomplete page unless it has so many bytes already downloaded.
