Base64 Programming Examples

Javascript

Encoding and decoding Base64 data can be done with the btoa() and atob() functions in Javascript.

// encode to base64
var encoded_text = btoa('some example text'); 
alert(encoded_text); // alerts "c29tZSBleGFtcGxlIHRleHQ="

// decode base64 
var decoded_text = atob('c29tZSBleGFtcGxlIHRleHQ=');
alert(decoded_text); // alerts "some example text"
			

PHP

Encoding and decoding Base64 data can be done with the base64_encode() and base64_decode() functions in PHP.

// encode to base64
$encoded_text = base64_encode('some example text'); 
echo $encoded_text; // echos "ZXhhbXBsZSB0ZXh0"

// decode base64 
$decoded_text = base64_decode('ZXhhbXBsZSB0ZXh0');
echo $decoded_text; // echos "some example text"
