Help understanding what this line of PHP is doing
<p>The variables values are listed below</p>

<pre><code>$v['flag'] = 10
kPOSTAGE_HOME = 8
</code></pre>

<p>So what the heck does the following line do?!</p>

<pre><code>if(($v['flag']&amp;kPOSTAGE_HOME)==kPOSTAGE_HOME) {
    //do something
}
</code></pre>
