The base64_encode_fromarray function encodes a base64 string from an array of characters or strings.

Syntax ​

base64_encode_fromarray( BytesArray )

Arguments ​

• BytesArray: Input array of characters or strings to be concatenated and encoded into base64. (Numbers within the array will be stringified as individual numeric characters.)

Results ​

Returns the base64 string encoded from the array of characters.

Trying to encode a base64 string from an invalid character array, which was generated from invalid UTF-8-encoded string, will return null.

Examples ​

This example encodes an array of familiar characters into its base64 string equivalent:

print enc=base64_encode_fromarray(dynamic(['C',"ri",'b','l']))

This example round-trips the input array to yield ["C","4","2","0",".","5","b","l"]:

print enc=base64_encode_fromarray(dynamic(['C',"420.5",'b','l'])),
dec=base64_decode_toarray(enc)
