This method adds a new entry to the set
public bool QuickHashIntSet::add ( int $key )
This method adds a new entry to the set, and returns whether the entry was added. Entries are by default always added unless QuickHashIntSet::CHECK_FOR_DUPES has been passed when the set was created.
Parameters:
key
The key of the entry to add.
Returns:
TRUE
when the entry was added, and FALSE
if the entry was not added.
Examples:
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)
