    QuickHashStringIntHash::delete — This method deletes an entry from the hash

    Descrizione

    public QuickHashStringIntHash::delete(string $key): bool

    This method deletes an entry from the hash, and returns whether the entry was deleted or not. Associated memory structures will not be freed immediately, but rather when the hash itself is freed.

    Elements can not be deleted when the hash is used in an iterator. The method will not throw an exception, but simply return false like would happen with any other deletion failure.

    Elenco dei parametri

    key

    The key of the entry to delete.

    Valori restituiti

    true when the entry was deleted, and false if the entry was not deleted.

    Esempi

    Example #1 QuickHashStringIntHash::delete() example

    <?php
    $hash     = new QuickHashStringIntHash( 1024 );
    var_dump( $hash->exists( 'four' ) );
    var_dump( $hash->add( 'four', 5 ) );
    var_dump( $hash->get( 'four' ) );
    var_dump( $hash->delete( 'four' ) );
    var_dump( $hash->exists( 'four' ) );
    var_dump( $hash->get( 'four' ) );
    var_dump( $hash->delete( 'four' ) );
    ?>

    Il precedente esempio visualizzerà qualcosa simile a:

    bool(false)
bool(true)
int(5)
bool(true)
bool(false)
bool(false)
bool(false)
