<code><?php

declare(ticks=1);
$start = microtime(true);
register_tick_function(function () use ($start) {
    (microtime(true) - $start < 0.5) or die("timeout\n");
});


function a() {
    echo "do some work\n";
    usleep(600000);
    echo "do another work\n";
}

a();
</code>

The above code shows a 500 millisecond timeout
