PHP - Add to Array
<p>How do I add to the end of each sub array?  Here is an example.</p>

<pre><code>$products = array( 
 array( Code =&gt; 'TIR', 
  Description =&gt; 'Tires', 
  Price =&gt; 100 
 ),
 array( Code =&gt; 'OIL', 
  Description =&gt; 'Oil', 
  Price =&gt; 10 
 ),
 array( Code =&gt; 'SPK', 
  Description =&gt; 'Spark Plugs', 
  Price =&gt;4 
 ) 
);
</code></pre>

<p>I want to add SKU=>1234 after Price in each array.  Thanks </p>
