This article will explain in detail how PHP uses md5 () to achieve encryption. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Use md5 () encryption

The md5 () function calculates the MD5 hash of a string, which is the most commonly used encryption method

The syntax of the md5 function is:

Md5 (string,raw)

Where string is the string to be encrypted, and row is an optional parameter that specifies the output format (hexadecimal or binary output format), which can be TRUE or FALSE, and defaults to FALSE (32-character hexadecimal numbers).

Examples of use:

Encrypt the password value and store it in the database.
