(PECL quickhash >= Unknown)
This method adds a new entry to the hash
public bool QuickHashIntHash::add ( int $key [, int $value ] )
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.
Returns:
TRUE when the entry was added, and FALSE if the entry was not added.
Examples:
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)
