title: PHP Parse this string
body: <p>I'm getting the following sample string through post parameter. I need to get the key value pair from the data to process further. I've used</p>
  
  <pre><code>json_decode($data)
  </code></pre>
  
  <p>But it throws an error. I copied the string into jsonlint and validated. The string is a valid <code>json</code></p>
