Php variable with operation in declaration of a drop down box
<p>How can I put a variable with operation in the declaration of a drop down box?
I have a drop down box with the months and when user selects March, the result of the code below is 2+1. I get this is handled as string function but I don't know how to make php handle it as it would result in 3.</p>

<pre><code>echo "&lt;option value=\"$i+1\"&gt;$month[$i]&lt;/option&gt;\n";
</code></pre>
