JSON Return from PHP to JavaScript

To return JSON data from PHP to JavaScript, utilize the built-in PHP function json_encode(). Here's how you can employ it:

$result = [
    ['line1', 'line2'],
    ['line1', 'line2'],
];

$json = json_encode($result);

$json will now contain a JSON-formatted string that can be easily parsed by JavaScript.

Instead of manually constructing JSON strings, it's recommended to leverage json_encode() as it provides error-handling and ensures data integrity.
