JSON: Array of Objects

See more JSON Examples

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"}
  ]
}

<?php

use Chilkat2\JsonObject;

$json = new JsonObject();

// 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"}]}';

try {
    $json->Load($jsonStr);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Get the "employees" array.
$employees = $json->ArrayOf('employees');
if ($employees === null) {
    echo "employees member not found.\n";
    exit;
}

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

    echo 'employee[', $i, '] = ', $empObj->StringOf('firstName'), ' ', $empObj->StringOf('lastName'), "\n";

    $i = $i + 1;
