    QuickHashIntHash::add — This method adds a new entry to the hash

    Description

    public QuickHashIntHash::add(int $key, int $value = ?): bool

    This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashIntHash::CHECK_FOR_DUPES has been passed when the hash was created.

    Parameters

    key

    The key of the entry to add.

    value

    The optional value of the entry to add. If no value is specified, 1 will be used.

    Return Values

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

    Examples

    Example #1 QuickHashIntHash::add() example

    <?php
    echo "without dupe checking\n";
    $hash = new QuickHashIntHash( 1024 );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 22 ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 12 ) );

    echo     "\nwith dupe checking\n";
    $hash = new QuickHashIntHash( 1024, QuickHashIntHash::CHECK_FOR_DUPES );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 78 ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, 9 ) );

    echo     "\ndefault value\n";
    var_dump( $hash->add( 5 ) );
    var_dump( $hash->get( 5 ) );
    ?>

    The above example will output something similar to:

    without dupe checking
bool(false)
bool(false)
bool(true)
bool(true)
int(22)
bool(true)

with dupe checking
bool(false)
bool(false)
bool(true)
bool(true)
int(78)
bool(false)

default value
bool(true)
int(1)
