    Descrição

        int $step = 1,
        bool &$success = ?,
        int $ttl = 0
    ): int|false

    Increases a stored number.

    Parâmetros

    key

    The key of the value being increased.

    step

    The step, or value to increase.

    success

    Optionally pass the success or fail boolean value to this referenced variable.

    ttl

    Exemplos

    Exemplo #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);
    ?>

    O exemplo acima produzirá algo semelhante a:

    Let's do something with success
42
43
53
63
bool(true)
Now, let's fail

bool(false)
bool(false)
