JSON vs XML
JSON is lighter, faster to parse, and natively supported by browsers. XML is better for document-centric data, namespaces, and legacy integrations.

JSON vs XML in PHP
Example
<?php
// JSON: compact, easy to parse
$json = '{"user":{"id":1,"name":"Alice","tags":["admin","editor"]}}';
$data = json_decode($json, true);
echo $data["user"]["name"]; // Alice
// XML: verbose but supports namespaces and attributes
$xml = simplexml_load_string('<user id="1"><name>Alice</name></user>');
echo (string) $xml->name; // Alice
// Convert XML to JSON
$xmlObj = simplexml_load_string($xmlString);
$json = json_encode($xmlObj); Pro Tip
Use JSON for APIs and JSON for inter-service communication. Use XML when integrating with SOAP services or when attributes/namespaces are needed.
