JSON Iterate Members

See more JSON Examples

Demonstrates how to loop over the immediate members of a JSON object. Chilkat2 PHP

<?php

use Chilkat2\JsonObject;

$json = new JsonObject();

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

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

$numMembers = $json->Size;
for ($i = 0; $i < $numMembers; $i++) {
    $name = $json->NameAt($i);
    $value = $json->StringAt($i);

    echo $name, ': ', $value, "\n";

    $iValue = $json->IntAt($i);
    echo $name, ' as integer: ', $iValue, "\n";
}

// Note: The StringAt method returns the value as a string regardless of the type.
// If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
// of the entire array is returned.

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