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

228 on 31-MAR-2005 with the following note:
229 "This means: $length should not be even,
230 but divisible by 4. The reason is that in
231 base64-encoding 3 8-bit-chars are represented
232 by 4 6-bit-chars. These 4 chars must not be
233 split between two encoded words, according
236 $length = $length - ($length % 4);
238 // encode the string and split it into chunks
239 // with spacers after each chunk
240 $out_str = base64_encode($out_str);
241 $out_str = chunk_split($out_str, $length, $spacer);
243 // remove trailing spacer and
244 // add start and end delimiters
