(PHP Extension) Compress EBICS SignaturePubKeyOrderData XML

This example provides a note about how to compress the SignaturePubKeyOrderData XML for EBICS.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// 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");

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// We have this XML to be compressed and then encoded in Base64.
