php function integer parameter problem
<pre><code>function is_zipcode_valid($zipcode){ ... }
</code></pre>

<p>if I call that function with <code>is_zipcode_valid(08004);</code>
my parameter 08004 gets in as 8004, basically it removed all precending 0's.</p>

<p>How can I get around that problem?</p>

<p>thanks</p>
