    Esempi

    Example #1 apcu_inc() example

    <?php
    echo "Let's do something with success", PHP_EOL;

    apcu_store('anumber', 42);

    echo     apcu_fetch('anumber'), PHP_EOL;

    echo     apcu_inc('anumber'), PHP_EOL;
    echo     apcu_inc('anumber', 10), PHP_EOL;
    echo     apcu_inc('anumber', 10, $success), PHP_EOL;

    var_dump($success);

    echo     "Now, let's fail", PHP_EOL, PHP_EOL;

    apcu_store('astring', 'foo');

    $ret = apcu_inc('astring', 1, $fail);

    var_dump($ret);
    var_dump($fail);
    ?>

    Il precedente esempio visualizzerà qualcosa simile a:

    Let's do something with success
42
43

bool(true)
Now, let's fail

bool(false)
