time33 hash function, also called Djbx33a,bernstein ' s hash
PHP, Apache, Perl, bsddb all use the time33 hash.
The simple hash is to use the combination of array plus list to achieve, this hash is very simple, but the idea of hash in that.#ifndef _hash_h_#define _hash_h_typedef struct _listnode{struct _listnode *prev;struct _listnode *next;void *data;}
The Hash algorithm in PHP. HashTable is the core of PHP. PHP arrays, associated arrays, object attributes, function tables, symbol tables, and so on all use HashTable as the container. PHP HashTable adopts the zipper Hash Table, which is the core of
Hash hash (1)
Hash is a common term and is often used in programming. However, most people know it, but they do not know it. In addition, they want to write a consistent hash algorithm over the past few days, suddenly I think it is not very clear
