Using foreach inside switch

[parka]

On a form there's a list of countries for the user to choose from.

 

On the processing script, how can I check to make sure that users have indeed choosen from the list I have provided?

 

I tried the following but it gave me a "parse error, unexpected T_FOREACH, expecting T_CASE or T_DEFAULT or '}'" on the line with the foreach statement.

 

How should I code this security check?

 

$countriesArray = array("usa", "china", "russia", "mexico");
$userChoosenCountry = "holland"; // to be replaced by $_POST later

switch ($userChoosenCountry){
foreach ($countriesArray as $country){
	case $country: print "You have choosen $country";
	break;
}
default: print "You didn't choose from the list of countries";
}

$countriesArray = array("usa", "china", "russia", "mexico");
$userChoosenCountry = "holland"; // to be replaced by $_POST later

if(in_array($userChoosenCountry,$countriesArray)) {
echo "you choose".$userChoosenCountry;
}
