convert_uuencode

(PHP 5, PHP 7, PHP 8)

convert_uuencodeUuencode 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.

Changelog

Version Description
8.0.0 Prior to this version, trying to convert an empty string returned false for no particular reason.

Examples

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 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.
