<?php

$crypt2 = new COM("Chilkat.Crypt2");

// ...
// ...

// ------------------------------------------------------------------------
// The DecodeString method is deprecated:

// The string "Hello World" in base64 (using the utf-8 byte representation) is "SGVsbG8gV29ybGQ="

$encodedStr = 'SGVsbG8gV29ybGQ=';
$encoding = 'base64';
$charset = 'utf-8';

$str = $crypt2->decodeString($encodedStr,$charset,$encoding);
print $str . "\n";

// Output is "Hello World"

// ------------------------------------------------------------------------
// Do the equivalent using StringBuilder.Decode.

$sb = new COM("Chilkat.StringBuilder");

$sb->Append($encodedStr);
$sb->Decode($encoding,$charset);
print $sb->getAsString() . "\n";

// Output is "Hello World"
