QuickHashIntStringHash::update
(PECL quickhash >= Unknown)
QuickHashIntStringHash::update — This method updates an entry in the hash with a new value
说明
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 QuickHashIntStringHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.
参数
-
key -
The key of the entry to update.
-
value -
The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.
返回值
true when the entry was found and updated, and false if the entry was
not part of the hash already.
