base64_encode - Encodes data with MIME base64

SYNOPSIS
string base64_encode (string $data) DESCRIPTION
Encodes the given $data with base64. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies. Base64-encoded data takes about 33% more space than the original data. PARAMETERS
o $data - The data to encode. RETURN VALUES
The encoded data, as a string or FALSE on failure. EXAMPLES
Example #1 base64_encode(3) example <?php $str = 'This is an encoded string'; echo base64_encode($str); ?> The above example will output: VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw== SEE ALSO

NAME
base64 - base64-encode/decode binary data SYNOPSIS
package require Tcl 8 package require base64 ?2.4? ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string ::base64::decode string _________________________________________________________________ DESCRIPTION
This package provides procedures to encode binary data into base64 and back. ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string Base64 encodes the given binary string and returns the encoded result. Inserts the character wrapchar every maxlen characters of output. wrapchar defaults to newline. maxlen defaults to 60. Note well: If your string is not simple ascii you should fix the string encoding before doing base64 encoding. See the examples. The command will throw an error for negative values of maxlen, or if maxlen is not an integer number. ::base64::decode string Base64 decodes the given string and returns the binary data. The decoder ignores whitespace in the string. EXAMPLES
% base64::encode "Hello, world" SGVsbG8sIHdvcmxk % base64::encode [string repeat xyz 20] eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6 eHl6eHl6eHl6 % base64::encode -wrapchar "" [string repeat xyz 20] eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6 # NOTE: base64 encodes BINARY strings. % set chemical [encoding convertto utf-8 "Cu2088Hu2081u2080Nu2084Ou2082"] % set encoded [base64::encode $chemical] Q+KCiEjigoHigoBO4oKET+KCgg== % set caffeine [encoding convertfrom utf-8 [base64::decode $encoded]] BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems.
