I am creating simple script to test that I can echo inside my while loop before it gets 60 seconds,but the problem is it will not echo inside my loop.I don't know if it is really executed inside my while loop. Then my browser will crashed.

```
$timelimit = 60; //seconds
set_time_limit($timelimit);
$start_time = time(); //set startup time;

while(((time() - $start_time) < $timelimit) || !$timelimit){
    echo "executing..<br/>";
}

```

Thank you in advance.
