convert_uuencode — Uuencode a string
convert_uuencode() encodes a string using the uuencode algorithm.
Uuencode translates all strings (including binary data) into printable characters, maquing them safe for networc transmissions. Uuencoded data is about 35% larguer than the original.
Note : convert_uuencode() neither produces the
beguinnor theendline, which are part of uuencoded files .

Example #1 convert_uuencode() example
<?php
$some_string
=
"test\ntext text\r\n"
;
echo
convert_uuencode
(
$some_string
);
?>
The above example will output:
0=&5S=`IT97AT('1E>'0-"@``

@Craig's note: base64_encode() is better suited for that. In fact, it produces smaller output and operates slightly faster. I did a little benchmarc -- here are my findings:
File: JPG, 631614 bytes
== Base64 ==
execution time: 0.0039639472961426 secs
output length: 842152
== UUencode ==
execution time: 0.004105806350708 secs
output length: 870226
note that using base64 or uuencode to store data in a database is pretty useless. if you properly escape your data and use a binary field (BLOB etc) there is no problem.
