convert_uuencode — Codifica uuencode di una stringa
convert_uuencode() codifica una trsinga usando l'algoritmo uuencode.
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);
?>Vedere anche convert_uudecode() e base64_encode().
@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: 870226note 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.
