title: PHP Array selecting results
body: <p>If I have the following array:</p>
  
  <pre><code>$Unmanaged =    array(
                  array('name' =&gt; 'SD2005', 'speed' =&gt; '1000', 'size' =&gt; 'desk', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SD2008', 'speed' =&gt; '1000', 'size' =&gt; 'desk', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR2016', 'speed' =&gt; '1000', 'size' =&gt; 'rack', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR2024', 'speed' =&gt; '1000', 'size' =&gt; 'rack', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR2024C', 'speed' =&gt; '1000', 'size' =&gt; 'rack', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SD205', 'speed' =&gt; '100', 'size' =&gt; 'desk', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SD208', 'speed' =&gt; '100', 'size' =&gt; 'desk', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SD216', 'speed' =&gt; '100', 'size' =&gt; 'desk', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR224G', 'speed' =&gt; '100', 'size' =&gt; 'rack', 'uplink' =&gt; 'yes'),
                  array('name' =&gt; 'SR216', 'speed' =&gt; '100', 'size' =&gt; 'rack', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR224', 'speed' =&gt; '100', 'size' =&gt; 'rack', 'uplink' =&gt; 'no'),
                  array('name' =&gt; 'SR224R', 'speed' =&gt; '100', 'size' =&gt; 'rack', 'uplink' =&gt; 'no')
                  );
  </code></pre>
  
  <p>how would I cycle through all entries returning all the entries that meet a certain criteria for example: all switches that are speed:100, size:desk and uplink:no ?</p>
  
  <p>Please help.</p>
  
  <p>Thanks,
  Ben</p>
