PHP: Best practice for validating Option Select
I have a html form with an option select for choosing a country name see sample code bellow
I'm wondering how to validate this part of the form in PHP using filter input
Will detect if no country has been selected because the value is 1
how would I validate a proper 3 figure country code
Is regex the best way or test for string length?

<div >
<select name="Country" >
<option selected value=1>Please select</option>
<option value="BRA">Brazil</option>
<option value="NZL">New Zealand</option>
<option value="SWZ">Switzerland</option>
</select>
</div>

Thanx for your suggestions
if (is_numeric($POST["Country
echo "No country selected";
} else {
$country = array("brazil", "new land", "xxxx", "yyy");
if (in_array($_POST["Country"
echo "Got it";
}
else
{
echo "no";
}
}
