PHP sleep delay

delayed-execution, for-loop, php, timedelay

Solution

Use `PHP sleep()` function. http://php.net/manual/en/function.sleep.php This stops execution of next loop for the given number of seconds. So something like this

for ($i=0; $i <= 10; $i++) {
    $file_exists=file_exists($location.$filename);
    if($file_exists) {
        break;
    }
    sleep(3); // this should halt for 3 seconds for every loop
}

Problem

In PHP, I want to put a number of second delay on each iteration of the loop. ``` for ($i=0; $i <= 10; $i++) { $file_exists=file_exists($location.$filename); if($file_exists) { break; } //sleep for 3 seconds } ``` How can I do this?
