title: PHP arrays - having an array as the key
body: <p>I know using an array as a key in a hash (associative array) in php will cause problems. </p>
  
  <p>Something like this:</p>
  
  <pre><code>        $array[$nominee]=$nominations;
  </code></pre>
  
  <p>where $nominee is an array itself.</p>
  
  <p>Its on a wordpress site, meaning i'm reluctant to leave it up live while I know/suspect theres an error. a very quick peek created an error with the word 'offset' in it. </p>
  
  <p>From memory, using <code>=&gt;</code> is needed, but can anyone give me the exact syntax??</p>
