QuickHashStringIntHash::update — This method updates an entry in the hash with a new value

Beschreibung

public bool QuickHashStringIntHash::update ( string $key , int $value )

This method updates an entry with a new value, and returns whether the entry was update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashStringIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

Parameter-Liste

key: The key of the entry to add.
value: The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

Rückgabewerte

TRUE when the entry was found and updated, and FALSE if the entry was not part of the hash already.
