title: Get specific value from json
body: <p>I have this json.  I only care about the uniqueIDs.</p>
  
  <p>How can I get ONLY the uniqueID values delivered back to me as a comma separated list, ie, 11111, 22222?  (I need to create my own array.)  I can't edit the json below - I am just trying to parse the value I care about out of it....</p>
  
  <pre><code>{
          products: [{
              type: "Unique",
              name: "Joe",
              description: "Joes Description",
              uniqueID: "11111"
          }, {
              type: "Unique",
              name: "Jane",
              description: "Janes Description",
              uniqueID: "22222"
          }]
  }
  </code></pre>
  
  <p>Thought it would be this easy but its not...</p>
  
  <pre><code>$data['uniqueID'][0]
  </code></pre>
