remove uncommon values in php array
<p>Hello all,</p>

<pre><code>Array ( 
    [0] =&gt; Array ( [id] =&gt; 242) 
    [1] =&gt; Array ( [id] =&gt; 24) 
    [2] =&gt; Array ( [id] =&gt; 234) 
    [3] =&gt; Array ( [id] =&gt; 244) 
)


Array ( 
    [0] =&gt; 24
    [1] =&gt; 242
    [2] =&gt; 244
)
</code></pre>

<p>When I used <code>print_r()</code>, I got above two arrays. Now, I need to filter two arrays and get uncommon values so my output will be 234</p>
