Base64_decode and Base64_encode encryption and decryption function instance _php technique in PHP

This article describes the Base64_decode and Base64_encode encryption and decryption functions in PHP. Share to everyone for your reference. The specific analysis is as follows:

These two functions in PHP are used to encrypt the PHP code and password Base64_encode is encrypted, and Base64_decode is decrypted, the following we look at two simple examples.

Base64_encode Syntax: String base64_decode (string data);

Copy Code code as follows:

$str = ' d3d3lmpinteubmv0ioiemuacros5i+wutg== '; Define String
echo Base64_decode ($STR); Output decoded content

Base64_encode Syntax: String base64_encode (string data);

Copy Code code as follows:

$str = ' www.jb51.net cloud-dwelling community '; Define String
echo Base64_encode ($STR); Output encoded after the content is: d3d3lmpinteubmv0ioiemuacros5i+wutg==
