title: Zabbix API search for two values in the same field
body: <p>I'm using Zabbix PHPAPI and I have a problem!</p>
  
  <p>How can you find two values ​​in the same field? For example:</p>
  
  <pre><code>$items[$h]=$zbx-&gt;itemGet(array (
          'filter' =&gt; ['hostid' =&gt; $arr[$h]['hostid']],
          'output' =&gt; ['itemid', 'LASTVALUE', 'name', 'key_']
          'search' =&gt; ['key_' =&gt; 'system.cpu.util', 'key_'=&gt;'system.cpu.util [all]'],
  ));
  </code></pre>
  
  <p>I took the test but it always considers the last parameter key_ </p>
