    Return Values

    true when the entry was added, and false if the entry was not added.

    Examples

    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)
