title: PHP -Sanitize values of a array
body: <p>I have a array, which comes from <code>$_POST[]</code> and can have other arrays in it as values, like:</p>
  
  <pre><code>array(
   'title' =&gt; 'Title',
   'data' =&gt; array(
               'hdr' =&gt; 'Header'
               'bdy' =&gt; 'Body'
             ),
    'foo' =&gt; array(1, 23, 65),
    ...
  )
  </code></pre>
  
  <p>How can I sanitize all values of this big array?
  for eg. apply a <code>strip_tags()</code> to values like <strong>Title</strong>, <strong>Header</strong>, <strong>Body</strong>, <strong>1</strong>, <strong>23</strong>, <strong>65</strong> etc ?</p>
