238 [EDIT BY danbrown AT php DOT net: The following

240 on 31-MAR-2005 with the following note:
241 "This means: $length should not be even,
242 but divisible by 4. The reason is that in
243 base64-encoding 3 8-bit-chars are represented
244 by 4 6-bit-chars. These 4 chars must not be
245 split between two encoded words, according
248 $length = $length - ($length % 4);
250 // encode the string and split it into chunks
251 // with spacers after each chunk
252 $out_str = base64_encode($out_str);
253 $out_str = chunk_split($out_str, $length, $spacer);
255 // remove trailing spacer and
256 // add start and end delimiters
