title: regular expression to split formatted string into associative array
body: <p>I have a string that looks like:</p>
  
  <pre><code>KEY1,"Value"KEY2,"Value"Key3,"Value"
  </code></pre>
  
  <p>This string will always vary in the number of keys/values i need an associative array:</p>
  
  <pre><code>array (
      'KEY1' =&gt; 'Value',
      'KEY2' =&gt; 'Value',
      'KEY3' =&gt; 'Value'
  );
  </code></pre>
  
  <p>of the data contained in the string, a regular expression would be best I suppose?</p>
