    QuickHashStringIntHash::update — This method updates an entry in the hash with a new value

    Beschreibung

    public QuickHashStringIntHash::update(string $key, int $value): bool

    This method updates an entry with a new value, and returns whether the entry was update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashStringIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

    Parameter-Liste

    key

    The key of the entry to update.

    value

    The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

    Rückgabewerte

    true when the entry was found and updated, and false if the entry was not part of the hash already.

    Beispiele

    Beispiel #1 QuickHashStringIntHash::update() example

    <?php
    $hash     = new QuickHashStringIntHash( 1024 );

    $hash->add( 'six', 314159265 );
    $hash->add( "a lot", 314159265 );

    echo     $hash->get( 'six' ), "\n";
    echo     $hash->get( 'a lot' ), "\n";

    var_dump( $hash->update( 'a lot', 314159266 ) );
    var_dump( $hash->update( "a lot plus one", 314159999 ) );

    echo     $hash->get( 'six' ), "\n";
    echo     $hash->get( 'a lot' ), "\n";
    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    314159265
314159265
bool(true)
bool(false)
314159265
