How To Apply UUEncode to a String? - PHP Script Tips - PHP Built-in Functions for Strings

UUEncode (Unix-to-Unix Encoding) is a simple algorithm to convert a string of any characters into a string of printable characters. UUEncode is reversible. The reverse algorithm is called UUDecode. PHP offeres two functions for you to UUEncode or UUDecode a string: convert_uuencode() and convert_uudecode(), Here is a PHP script on how to use them:

<?php
$msgRaw = "
From\tTo\tSubject
Joe\tLee\tHello
Dan\tKia\tGreeting";
$msgEncoded = convert_uuencode($msgRaw);
$msgDecoded = convert_uudecode($msgEncoded);
if ($msgRaw === $msgDecoded) {
  print("Conversion OK\n");
  print("UUEncoded message:\n");
  print("-->$msgEncoded<--\n");
  print("UUDecoded message:\n");
  print("-->$msgDecoded<--\n");
} else {
  print("Conversion not OK:\n");
}
?>

This script will print:

Conversion OK
UUEncoded message:
-->M1G)O;0E4;PE3=6)J96-T#0I*;V4)3&5E"4AE;&QO#0I$86X)2VEA"4=R965T
#:6YG
`
<--
UUDecoded message:
-->
From    To      Subject
Joe     Lee     Hello
Dan     Kia     Greeting<--

The output shows you that the UUEncode string is a multiple-line string with a special end-of-string mark \x20.
