Display the output while looping in php

Question

Is it possible to display string on the browser while in infinite loop? This is what I want to happen:

while(1) {
     echo "should display these lines on browser while in infinite loop.<br>";
}

Answer 1

Yes, it is possible. You need to flush the output to the browser if you want it to appear immediately:

while(1) {
     echo "should display these lines on browser while in infinite loop.<br>";
     flush();
}

Chances are that whatever you're trying to accomplish, this isn't how you should go about it.

PHP will eventually time-out, but not before it generates a massive HTML document that your browser will have trouble displaying.
