How to implement base64 encryption by php

This article is about how php implements base64 encryption. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In php, you can use the base64_encode () function to implement base64 encryption, which can base64 encode string data with the syntax "base64_encode ($data)"; if the encryption succeeds, it returns the string encoded by base64; if it fails, it returns False.

In php, you can use the base64_encode () function to implement base64 encryption and the base64_decode () function to achieve decryption.

The base64_encode () function is a built-in function in PHP that is used to encode data using MIME base64. MIME (Multipurpose Internet Mail extension) base64 is used to encode strings into base64. Base64_encoded data takes up 33% more space than the original data.

Syntax:

Base64_encode ($data)

This function accepts a mandatory single argument, $data. It is used to specify string encoding.

Return value: this function returns the encoded string in base64 on success or False on failure.
