title: using array_walk on multidimensional array
body: <p>I have an array like this</p>
  
  <pre><code>Array ( [0] =&gt; Array ( [keyword] =&gt; nothing [id] =&gt; 44 ) [1] =&gt; Array ( [keyword] =&gt; everything [id] =&gt; 45 ) [2] =&gt; Array ( [keyword] =&gt; dogs [id] =&gt; 46 ) )
  </code></pre>
  
  <p>I basically want to create a link like this:</p>
  
  <pre><code>&lt;a href="mypage.php?pid=ID"&gt;KEYWORD&lt;/a&gt;
  </code></pre>
  
  <p>So I was thinking about using array_walk, but I dont think this will work on a multidimensional array, how do I go about getting it to iterate through my array and output the ID and keyword for each one of my entries in the array?</p>
