    Beschreibung

    publicQuickHashIntHash::add(int$key, int$value = ?): bool

    This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashIntHash::CHECK_FOR_DUPES has been passed when the hash was created.

    Parameter-Liste

    key

    The key of the entry to add.

    value

    The optional value of the entry to add. If no value is specified, 1 will be used.

    Rückgabewerte

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

    Beispiele

    Beispiel #1 QuickHashIntHash::add() example

    <?php
    echo "without dupe checking\n";
    $hash = new QuickHashIntHash( 1024 );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 22 ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 12 ) );

    echo     "\nwith dupe checking\n";
    $hash = new QuickHashIntHash( 1024, QuickHashIntHash::CHECK_FOR_DUPES );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 78 ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 9 ) );

    echo     "\ndefault value\n";
    var_dump( $hash->add( 5 ) );
    var_dump( $hash->get( 5 ) );
    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    without dupe checking bool(false) bool(false) bool(true) bool(true) int(22) bool(true) with dupe checking bool(false) bool(false) bool(true) bool(true) int(78) bool(false) default value bool(true) int(1)
