convert_uuencode — Uuencode a string

Description

convert_uuencode(string $string): string

convert_uuencode() encodes a string using the uuencode algorithm.

Uuencode translates all strings (including binary data) into printable characters, making them safe for network transmissions. Uuencoded data is about 35% larger than the original.

Note: convert_uuencode() neither produces the begin nor the end line, which are part of uuencoded files.

Parameters

string: The data to be encoded.

Return Values

Returns the uuencoded data.

@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
