Hi William,
I'm not quite shure if You got the same problem like I do. I tried to
simplify the whole thing:
$i = 0;
while ($i++ < 10)
{
// Output to a new page!?!
print("<html>");
print("<head>");
print("<title>Titel</title>");
print("</head> \n");
print("<body> \n");
print("Test $i \n");
print("</body> \n");
print("</html> \n");
flush();
ob_flush();
sleep(2);
}
In spite of opening a new page in every walkthrough and showing Testx on
new pages, the code shows a long row of Test1 Test2 etc. on o n e page.
Is that Your problem?
I'm not unexperienced in programming but new to php and web-server
programming. Most probably this is a very simple thing and we don't see
the forest because of all those trees!
I would be highly appreciated, if You tell me as soon as You'll solve
the problem.
