JSON: Access Array Values

See more JSON Examples

Demonstrates how to access values in a JSON array. Chilkat2 PHP

<?php

use Chilkat2\JsonObject;

$json = new JsonObject();

$jsonStr = '{ "id": 1, "name": "A green door", "tags": ["home", 22, "green"], "price": 125 }';

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

// Get the "tags" array, which contains "home", 22, "green"
$tagsArray = $json->ArrayOf('tags');
if ($tagsArray === null) {
    echo "tags member not found.\n";
    exit;
}

// Get the value at each array index.
// Output will be:
// [0] = home
// [0] as integer = 0
// [1] = 22
// [1] as integer = 22
// [2] = green
// [2] as integer = 0

$arraySize = $tagsArray->Size;
for ($i = 0; $i < $arraySize; $i++) {
    $sValue = $tagsArray->StringAt($i);

    echo '[', $i, '] = ', $sValue, "\n";

    $iValue = $tagsArray->IntAt($i);
    echo '[', $i, '] as integer = ', $iValue, "\n";
}

// Note: The StringAt method returns the value as a string regardless of the type.

// The IntAt method returns the value as an integer.  If the value does not convert to
// an integer, then 0 is returned.
