QuickHashStringIntHash::set — This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist

説明

public QuickHashStringIntHash::set(string $key, int $value): int

This method tries to update an entry with a new value. In case the entry did not yet exist, it will instead add a new entry. It returns whether the entry was added or 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.

パラメータ

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

戻り値

2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.
