merging two arrays and keep duplicate values
<p>Is there a php function to merge 2 arrays and keep duplicates?</p>

<p>Like:</p>

<pre><code>$a=array('a','b','c');
$b=array('b','c','b');
array_merge2($a,$b);
//result: array('a','b','c','b','c','b');
</code></pre>

<p>thanks</p>

<p>add1:</p>

<p>what the... i previously tested array_merge and it didn't keep duplicate values =/</p>
