a hash table, also known as a hash table, is a data structure that is accessed directly from a key value. That is, it accesses records by mapping key code values to a location in the table to speed up lookups. This mapping function is called a hash

The topic of the hash table collision attack (HashtablecollisionsasDOSattack) has been repeatedly mentioned, and various languages have been recruited. This article combines the PHP kernel source code to discuss the principles and implementation of
