QuickHashStringIntHash::deleteThis method deletes an entry from the hash

Açıklama

public QuickHashStringIntHash::delete(string $key): bool

This method deletes an entry from the hash, and returns whether the entry was deleted or not. Associated memory structures will not be freed immediately, but rather when the hash itself is freed.

Elements can not be deleted when the hash is used in an iterator. The method will not throw an exception, but simply return false like would happen with any other deletion failure.
