MD5 is the most common cryptographic algorithm in Web applications. Because MD5 is irreversible, the ciphertext obtained after MD5 calculation cannot be obtained through reverse algorithms. Looking back at the original intention of using MD5 to

PHP Learning--php Encryption, PHP learning--php encryption There are several types of encryption in PHP: 1. MD5 Encryption String MD5 (string $str [, bool $raw _output = false]) Parameters STR--the original string. Raw_output--If the optional

The scenario for generating a unique ID is very common, such as temporary cache file names, temporary variables, temporary security codes, and so on, and the uniqid () function generates a unique ID based on the current time in microseconds. Because
