I guess you mean [2][1] on the last line. A more instructive array
definition with the same result:
$a = array(
array('Name', $name),
array('Message', $msg),
array('Subject', $subj)
);

As you can see above, $a[0] is an array containing two items: 'Name' and
$name. So $v1 (an alias for $a[0], $a[1], etc.) is not the fieldname, but
$v1[0] is. A better way would be:
foreach ($a as $field) {
list($fieldname, $fieldvalue) = $field;
Or maybe even:
$a = array(
array('name' => 'Name', 'value' => $name),
array('name' => 'Message', 'value' => $msg),
array('name' => 'Subject', 'value' => $subj)
);
foreach ($a as $field)
echo "{$field['name']} = {$field['value']}<br />\n";
