title: Doing a PHP in_array() but with a needle of one another array()
body: <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>
