PHP output to browser.

Hi,

Take this sample loop:


for($i = 1; $i <= 4; $i++) {
print $i."<br>";
sleep(2);
}


When you run the above, it will output all numbers at once. How we can print each number to the browser and wait 2 seconds, then print the other one?

You can try using flush() but be warned it isn't guaranteed to work. Thats because of the way http works.

You'll need to use Javascripting for that.
