Is there any flush() equivalent that I can use to modify this script (posted in the manual) so it works on Win32 servers?

PHP Code:
<html> 

<table border=1><tr><td id=fisk> 
I am inside a table. 
</td></tr></table> 

<? flush(); sleep(2); ?> 

<script> 
document.all.fisk.innerHTML= document.all.fisk.innerHTML + "
I am still inside a table..."; 
</script> 

<? flush(); sleep(2); ?> 

<script> 
document.all.fisk.innerHTML= document.all.fisk.innerHTML + "
Hehhee...."; 
</script> 

</html>
If this is possible, it would be a life saver.
