ABOUT

This library allows you to connect to existing ql-nodes and use their API to interact with the Qubic Lite protocol.

USE

1. download qlite.php and put it into your project's directory

2. include the library into your .php file

include('../qlite.php');

3. initialize a new qlite instance in your php script

$qlite = new Qlite('https://qlnode.org:17733');

4. send requests

$my_qubic = "GAPGBVIBDKTGZ9BVLCZYWPZAFMIXBDLCUTXOC9NEJ9HGDKZYGRPQVIHMZXRXCDLZIFXGECZBFSTTNA999";

try {
    $res = $qlite->qubic_read($my_qubic);
    echo "qubic code: $res[code]";
} catch (Exception $exc) {
    echo "an exception occured: $exc";
}
