Description
string convert_uuencode
( string
$data
)convert_uuencode() encodes a string using the uuencode algorithm.
Uuencode translates all strings (including binary's ones) into printable characters, making them safe for network transmissions. Uuencoded data is about 35% larger than the original.
Parameters
-
data -
The data to be encoded or
FALSEon failure.
Return Values
Returns the uuencoded data.
Examples
Example #1 convert_uuencode() example
<?php
$some_string = "test\ntext text\r\n";
echo convert_uuencode($some_string);
?>

@Craig's note: base64_encode() is better suited for that. In fact, it produces smaller output and operates slightly faster. I did a little benchmark -- 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.
