The form above has three checkboxes, all named languages[]; these will all be added
individually to an array called languages in the $_POST superglobal array—just like
when you use an empty key (e.g. $array[] = “foo”) to append a new element to an
existing array in PHP. Once inside your script, you will be able to access these values
as follows:
foreach ($_POST[’languages’] as $language) {
switch ($language) {
case ’PHP’ :
echo "PHP? Awesome! ";
break;
case ’Perl’ :
echo "Perl? Ew. Just Ew. ";
break;
case ’Ruby’ :
echo "Ruby? Can you say... ’bandwagon?’ ";
break;
default:
echo "Unknown language!";
}
}

When You Don’t Know How Data Is Sent
If you need to write a script that is supposed to work just as well with both GET and
POST requests, you can use the $_REQUEST superglobal array; the latter is filled in
using data from different sources in an order specified by a setting in your php.ini
