    Ds\Set::contains

    (PECL ds >= 1.0.0)

    Ds\Set::contains — Determines if the set contains all values

    Descrizione

    public Ds\Set::contains(mixed ...$values): bool

    Determines if the set contains all values.

    Nota:

    Values of type object are supported. If an object implements Ds\Hashable, equality will be determined by the object's equals function. If an object does not implement Ds\Hashable, objects must be references to the same instance to be considered equal.

    Attenzione

    All comparisons are strict (type and value).

    Elenco dei parametri

    values

    Values to check.

    Valori restituiti

    false if any of the provided values are not in the set, true otherwise.

    Esempi

    Example #1 Ds\Set::contains() example

    <?php
    $set     = new \Ds\Set([1, 2, 3]);

    var_dump($set->contains(1)); // true
    var_dump($set->contains(1, 2)); // true
    var_dump($set->contains(...[1, 2])); // true

    var_dump($set->contains("1")); // false
    var_dump($set->contains(...[1, 2, 3, 4])); // false

    var_dump($set->contains(...[])); // true
    ?>

    Il precedente esempio visualizzerà qualcosa simile a:

    bool(true)
bool(true)
bool(true)
bool(false)
bool(false)
bool(true)
