title: PHP: Check if an array contains all array values from another array
body: <pre><code>$all = array
  (
      0 =&gt; 307,
      1 =&gt; 157,
      2 =&gt; 234,
      3 =&gt; 200,
      4 =&gt; 322,
      5 =&gt; 324
  );
  $search_this = array
  (
      0 =&gt; 200,
      1 =&gt; 234
  );
  </code></pre>
  <p>I would like to find out if <code>$all</code> contains all <code>$search_this</code> values and return <code>true</code> or <code>false</code>. Any ideas please?</p>
