(PHP 5)

convert_uuencode Codifica uuencode di una stringa

Descrizione

string convert_uuencode ( string $data )

L'algoritmo uuencode codifica tutte le stringhe (comprese quelle binarie) in caratteri stampabili, rendendole sicure per la trasmissione via rete. I dati così codificati hanno una dimensione del 35% superiore all'originale.

Example #1 Esempio di uso di convert_uuencode()

<?php
$some_string 
"test\ntext text\r\n";
echo 
convert_uuencode($some_string);
?>

Using uuencode for passwords isn't any more secure than plain text (maybe slightly: non-developers or too lazy to figure out what you used). mcrypt or even md5 is much more secure.

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.

Note to the tip of Craig at frostycoolslug dot com:

If you are using fulltext functionality on columns with uuencoded texts, collations will not work. You might prefer to pass the text escaped to the database engine.

@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

if you want to use convert_uuencode with command uudecode you must insert a line "begin %s %s\n" at the beginning and "end\n" at the end:

<?php

echo "begin 644 hello.txt\n";
echo
convert_uuencode("hello");
echo
"end\n";

?>

the first arg. after begin is the mode (destination file rights), the second is the destination file name.

Then you can do a wget followed by a uudecode.

JA.

uuencode is recognisable as email attachment in Ms Outlook, but in Outlook Express (at least in older versions) - is not.

This is shell script, but it may give you an idea how you can send attachments using uuencode:

cat file.bin | uuencode file.bin | mail someone@domain.com -s "file.bin"

uuencode mail attachments from other point of wiev are deprecated. However I use such technic for years now and it work well.
