// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$s = '&eacute; &#233; &#xE9;';

$sb = new CkStringBuilder();

$sb->Append($s);
$sb->EntityDecode();

// The string now contains: "é é é"
print $sb->getAsString() . "\n";

// If encoded to hex using the iso-8859-1 charset, 
// each é char is represented in 1 byte.
// Output: E920E920E9
print $sb->getEncoded('hex','iso-8859-1') . "\n";

// If encoded to hex using the utf-8 charset, 
// each é char is represented in 2 bytes.
// Output: C3A920C3A920C3A9
print $sb->getEncoded('hex','utf-8') . "\n";

// Here's utf-16
// Output: E9002000E9002000E900
print $sb->getEncoded('hex','utf-16') . "\n";

// utf-32
// Output: E900000020000000E900000020000000E9000000
