Demonstrates console output using Chilkat JavaScript. PHP Extension

<?php

include("chilkat.php");

$success = false;

// This example demonstrates using the built-in console object.
// The Javascript run in this example is shown below.

// Load the JavaScript from a file.
$sbScript = new CkStringBuilder();
$success = $sbScript->LoadFile('qa_data/js_tests/test_console.js','utf-8');
if ($success == false) {
    print $sbScript->lastErrorText() . "\n";
    exit;
}

$js = new CkJs();
$result = new CkJsonObject();

// Run the JavaScript
// Results (not console output) go to result.
// Note: Eval returns the completion value of the script. This is generally the value of the last evaluated expression.
// In this case, the last evaluated expression is console.log which does not calculate a value. Therefore, it returns undefined.
$success = $js->Eval($sbScript,$result);
if ($success == false) {
    print $sbScript->lastErrorText() . "\n";
    exit;
}

// We can look at the result, which is "undefined", which is normal and expected.
print $result->emit() . "\n";
// The result JSON is: {"type":"undefined","value":"undefined"}

// The console output is retrieved by calling ConsoleOutputSb
$sbOut = new CkStringBuilder();
$js->ConsoleOutputSb($sbOut);
print $sbOut->getAsString() . "\n";
