title: how to get specific values from curl response in php
body: <p>I have the following format of response from using curl:</p>
  
  <pre><code>{
      "result": {
          "total": 1,
          "userquery": "my own query",
          "items": [
              {
                  "coord": {
                      "a": -326.9159528,
                      "b": 12.0192037
                  }
              }
          ]
      }
  }
  </code></pre>
  
  <p>I want to save the parts after "a": and "b": so only the two sets of number will be saved in php variables.</p>
  
  <p>How can I do it? And what would be the best way of doing it?</p>
