Remove duplicates from array
<p>I have two arrays, like this:</p>

<pre><code>$array1 = array(
'ADAIR',
'ADAM',
'ADAMINA',
'ADDISON',
'ADDY',
'ADELLE',
'ADEN',
'ADOLPH',
'ADRIANNA'
);

$array2 = array(
'ADAIR',
'ADAMINA',
'ADRIANNA'
);
</code></pre>

<p>How do I make a third array, without duplicates? <strong>We should take first array and remove from it duplicates from second array.</strong></p>
