Doing a PHP in_array() but with a needle of one another array()
<p>I need something like <code>in_array()</code> for search if at least one of <code>$foo</code> is in <code>$bar</code>array, like:</p>

<pre><code>$foo = array("ESD", "RED", "IOP");
$bar = array("IOD", "MNP", "JDE", "RED");

if(in_array($foo, $bar)) // true because RED is in $foo and in $bar
</code></pre>

<p>Thank you in advance!</p>
