Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

How to do it…

Here's a simple example:

<html>
<body>
<pre>
<?php
  require_once('jsonpath.php');
  $json = '…'; // from the introduction to this chapter
  $object = json_decode($json);
  $titles = jsonPath($object, "$..title");
  print($titles);
?>
</pre>
</body>
</html>

How it works…

The preceding code begins by requiring the PHP JSONPath implementation, which defines the jsonPath...
