[PHP] sleep function

[virtualsoftware]

Hi,

I want to create a script that displays all names from a database once per 
second. 
A part of the script look like this.

for ($i=0; $i<$total_names; $i++)
    {
      echo "name<br>";
      sleep (1);
    }

The scipt works fine but it displays all names at once. I want to display the 
first name, then refresh the browser and display the first name and the second, 
then the first name, the second and the third ....and so on.
Can someone please tell me how can i do this?


Thanks in advance for your help !!!
