    例

    例1 QuickHashIntStringHash::add() example

    <?php
    echo "without dupe checking\n";
    $hash = new QuickHashIntStringHash( 1024 );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "twenty two" ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "twelve" ) );

    echo     "\nwith dupe checking\n";
    $hash = new QuickHashIntStringHash( 1024, QuickHashIntStringHash::CHECK_FOR_DUPES );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "seventy eight" ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "nine" ) );
    ?>
