return json data from string
<p>I hope you can help.</p>

<p>I'm using <a href="https://github.com/campaignmonitor/createsend-php/blob/master/class/base_classes.php" rel="nofollow">campaign monitors</a>
 PHP wrapper.</p>

<p>This is what the call returns:</p>

<pre><code>CS_REST_Wrapper_Result Object ( [response] =&gt; HTTP/1.1 202 Accepted Server: csw Cache-Control: private, s-maxage=0 Content-Type: application/json; charset=utf-8 P3P: CP="OTI DSP COR CUR IVD CONi OTPi OUR IND UNI STA PRE" Date: Sun, 14 Feb 2016 13:38:18 GMT X-RateLimit-Limit: 50000 X-RateLimit-Reset: 366 X-RateLimit-Remaining: 49995 Content-Length: 216 [{"MessageID":"2e992358-d320-11e5-b287-c903ee0bee99","Recipient”:”test@test.co.uk”,”Status":"Accepted"},{"MessageID":"2ea9d51f-d320-11e5-9c7a-edc47069cc09","Recipient":"test2@test.co.uk","Status":"Accepted"}] [http_status_code] =&gt; 202 )  
</code></pre>

<p>I want to be able to loop through the "Message ID's" but the [response] is a string containing the header info? </p>
