Question

I`m using the php command microTime(true) to retrieve time from the server.

I would like to fire off an event every time an complete second is reached, I need accuracy of microsecomds to determine when a complete second is reached.

This is the code i have so far:

$time_start = microtime(true);

while($someValue){
    if(microtime(true)==time()){
        echo "<p>".microtime(true)."</p>";
        echo "<p>".time()."</p>";
    }

    //sleep for one microsecond
    usleep(1);
} 

Can someone help or explain to me how to get this right?

Answer 1

Why not using usleep only once?

usleep(1000);

Are you sure that it will be less precise? I don’t see how…
