title: jQuery JSON string versus PHP json_encode
body: <p>I was looking at my database and there were places where jQuery had been used to make a JSON string:</p>
  
  <pre><code>{"0":"33"}
  </code></pre>
  
  <p>And then I saw places where there were JSON strings made from PHP json_encode like:</p>
  
  <pre><code>["News"," world news"," latest news"]
  </code></pre>
  
  <p>Do the brackets versus braces make a difference? </p>
