    Example #1 QuickHashStringIntHash::add() example

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

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

    Il precedente esempio visualizzerà qualcosa simile a:

    without dupe checking
object(QuickHashStringIntHash)#1 (0) {
}
bool(false)
bool(false)
bool(true)
bool(true)
int(22)
bool(true)

with dupe checking
object(QuickHashStringIntHash)#2 (0) {
}
bool(false)
bool(false)
bool(true)
bool(true)
int(78)
bool(false)
