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 ) ); ?>
