    You can unregister closure-function:

    declare(ticks = 1000);
    $startTime = microtime(true);
    $tick = true;
    $closure = function () use ($startTime, &$tick) {
        if (((microtime(true) - $startTime) > 5) && $tick) {
            $tick = false;
            throw new \Exception('Time to run code left');
        }
    };

    try {
                register_tick_function($closure);
                //do your code
                $result = 1;
                return $result;
            } catch (\Exception $e) {
                throw $e;
            } finally {
                unregister_tick_function($closure);
    }

    It's not so clear, but, at least as of PHP 5.3.13, you cannot use this inside of the handler itself as it will throw an error:

    <?php

    declare(ticks=2);

    function     tick_handler()
    {
            unregister_tick_function('tick_handler');
    }

    register_tick_function('tick_handler');

    set_time_limit(0);
    usleep(500000);

    ?>

    results in:

    warning: unregister_tick_function(): Unable to delete tick function executed at the moment in [filename]

    So if you want to unregister it must be done outside of the handler.

    Note that unregister_tick_function() can also accept a callback in the form of an array (either static, like array($className, $methodName) or instance, like array(&$this, $methodName)).

    It cannot accept an anonymous function, however.
