Why doesn't this PHP if statement work?
<p>I have a parameter in the url for birthday <code>?user_birth_day=05</code>, and I have the following codes:</p>

<pre><code>&lt;?php echo $_REQUEST['user_birth_day']; ?&gt; // this outputs 5

&lt;?php for ($i = 1; $i &lt;= 31; $i++) : ?&gt;                     
    &lt;?php if($_REQUEST['user_birth_day'] === $i){ echo 'BINGO'; } ?&gt;
&lt;?php endfor; ?&gt;
</code></pre>

<p>The if statement simply prints nothing. Please help!</p>
