title: How to parse a JSON string using PHP
body: <p>I have a JSON string that has 1-n numbers of lat/lng records. It looks something like this:</p>
  
  <pre><code>{\"lat\":37.790388261934424,\"lng\":-122.46047996826172},{\"lat\":37.789608231530124,\"lng\":-122.46344112701416}
  </code></pre>
  
  <p>What is a good way to parse this to get lat/lng values loop?  And do the escaped double quotes impact the parsing?</p>
  
  <p>Thanks,
  Alex</p>
