    Приклад #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 ) );
    ?>

    Поданий вище приклад виведе щось схоже на:

    without dupe checking
bool(false)
bool(false)
bool(true)
bool(true)
int(22)
bool(true)

with dupe checking
