PHP with base64_encode() Function

 

PHP | base64_encode() Function

The base64_encode() function is an inbuilt function in PHP which is used to Encodes data with MIME base64. MIME (Multipurpose Internet Mail Extensions) base64 is used to encode the string in base64. The base64_encoded data takes 33% more space than the original data.

 Syntax:

string base64_encode( $data )

Parameters: This function accepts single parameter $data which is mandatory. It is used to specify the string encoding. Return value: This function returns the encoded string in base64 on success or returns False in case of failure. Below programs illustrate the base64_encode() function in PHP: Program 1: 

• php

<?php   // Program to illustrate base64_encode() // function $str = 'androidphp';   echo base64_encode($str); ?>

In PHP, base64_encode() is a function that encodes data using the Base64 encoding scheme.

What is Base64 Encoding?

• Purpose: Base64 is a method for representing binary data (like images, audio, or even plain text) in a text format. This is crucial when you need to transmit or store data that isn’t inherently text-based.
• How it works: It translates binary data into a set of 64 characters:
• Uppercase and lowercase letters (A-Z, a-z)
• Digits (0–9)
• Plus sign (+)
• Slash (/)
• Why it’s useful:
• Safe for transmission: Many protocols (like email) are designed for text. Base64 ensures your binary data can be safely transmitted without corruption.
• Easy to handle: Encoded data is represented as text, making it easier to store and manipulate in various systems.
