 <strong>that contains a single item</strong>.  This item can be an array with several additional arrays, but there

 can be only one primary array index.  In other words, the basic prototype is this:</p>

 

-<code>$request = array('Response data',  'array');</code>

+<code>$response = array('Response data',  'array');</code>

 

 <p>Responses, however, usually contain multiple pieces of information. In order to accomplish this we must put the response into its own

 array so that the primary array continues to contain a single piece of data.  Here's an example showing how this might be accomplished:</p>

 

 <code>

-$request = array (<br />

+$response = array (<br />
