Example #1 QuickHashIntSet::add() example

<?php
echo "without dupe checking\n";
$set = new QuickHashIntSet( 1024 );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );

echo "\nwith dupe checking\n";
$set = new QuickHashIntSet( 1024, QuickHashIntSet::CHECK_FOR_DUPES );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
?>

The above example will output something similar to:

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

with dupe checking
bool(false)
bool(true)
bool(true)
bool(false)
