Parameters

Returns

Returns the base64 string encoded from the bytes array. Note that byte is an integer type.

Examples

The following example shows how to use base64_encode_fromarray() to encode a bytes array into a base64 string.

let bytes_array = toscalar(print base64_decode_toarray("S3VzdG8="));
print decoded_base64_string = base64_encode_fromarray(bytes_array)

Output

Trying to encode a base64 string from an invalid bytes array that was generated from invalid UTF-8 encoded string will return null:

let empty_bytes_array = toscalar(print base64_decode_toarray("U3RyaW5n0KHR0tGA0L7Rh9C60LA"));
print empty_string = base64_encode_fromarray(empty_bytes_array)

Output
