If your process uses SIGALRM and sleep() at the same time, the alarm set could make sleep() to
return prematurely.
To avoid this and ensure your process waits a number of seconds you could use a function or class
similar to this one:
<?php
class SleepWorkaroundForSIGALRM {
private $time;
function __construct($seconds) {
$this->time = time() + $seconds;
while ($this->time >= time()) {
sleep(1);
}
}
?>
