Demonstrates ascii85 encoding and decoding.

Note: Requires Chilkat v9.5.0.79 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// First demonstrate encoding strings to ascii85 and back.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')

$success = $sb->Append('Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.');

$encodedAscii85 = $sb->getEncoded('ascii85','utf-8');
print $encodedAscii85 . "\n";

// Result is: 9jqo^BlbD-BleB1DJ+*+F(f,q/0JhKF<GL>Cj@.4 ... DII?(E,9)oF*2M7/c

// Decode back to the original:
