declare(ticks=1);
// A function called on each tick event
 function tick_handler()
 {
 echo "tick_handler() called\n";
  }

 register_tick_function('tick_handler');

 $a = 1;

$a += 2;
print($a);
}

 ?>  

i got the following error message “The connection to the server was reset while the page was loading.”.

Ticks are dependent on the web server that’s running PHP, the version of PHP and other PHP modules installed. From the docs:

register_tick_function() should not be used with threaded web server modules with PHP 5.2 or lower.

If you’re using PHP 5.3+ the code sample should run fine. (I’m running 5.3 and the sample performs as promised). Otherwise, check your web server config.
