(PHP Extension) JSON: Array of Objects

Here we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array.

{ 
  "employees":[
    {"firstName":"John", "lastName":"Doe"},
    {"firstName":"Anna", "lastName":"Smith"},
    {"firstName":"Peter","lastName":"Jones"}
  ]
}

// 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");

$json = new CkJsonObject();

// This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars).
// The presence of whitespace chars for pretty-printing makes no difference to the Load
// method. 
$jsonStr = '{\'employees\':[{\'firstName\':\'John\', \'lastName\':\'Doe\'},{\'firstName\':\'Anna\', \'lastName\':\'Smith\'},{\'firstName\':\'Peter\',\'lastName\':\'Jones\'}]}';

$success = $json->Load($jsonStr);
if ($success != true) {
    print $json->lastErrorText() . "\n";
    exit;
}

// Get the "employees" array.
// employees is a CkJsonArray
$employees = $json->ArrayOf('employees');
if ($json->get_LastMethodSuccess() == false) {
    print 'employees member not found.' . "\n";
    exit;
}

// Iterate over each employee, getting the JSON object at each index.
$numEmployees = $employees->get_Size();
$i = 0;
while ($i < $numEmployees) {

    // empObj is a CkJsonObject
    $empObj = $employees->ObjectAt($i);

    print 'employee[' . $i . '] = ' . $empObj->stringOf('firstName') . ' ' . $empObj->stringOf('lastName') . "\n";

    $i = $i + 1;
