Sleep inside a while loop, help please!

Basically I want to loop through and open a new url in each iFrame, but between each iFrame there must be a 2.2 second delay. But it's not doing that, what it's doing is delaying, then loading all of the iFrames at once.

Any suggestions?

<?php

$url = "www.site.com/id=";

$id = 100000005;
$delay = 2.2;

$x = 5;

while($x > 0) {

       Sleep($delay);
       echo '<iframe name="FRAMENAME" src="'.$url . $id.'" width="100" height="280" style="border: 10 solid #0415FB" scrolling="no" allowautotransparency=true></iframe>';
       $x--;
       $friendid++;

}

?>

Thanks!

 

You need to flush PHP's output buffers after each iteration to get the effect you desire.

<?php

$delay = 1;
// max number of iterations
$it = 10;

while($it > 0)
{
	echo $it;
	flush();
	sleep($delay);
	$it--;
}

?>

Tested on Centos4/PHP5.

If that does not work for you try

<?php

$delay = 1;
// max number of iterations
$it = 10;

while($it > 0)
{
	echo $it;
	ob_flush();
	flush();
	sleep($delay);
	$it--;
}

?>

You can also use usleep($microseconds) for more accurate delays.
