How to get a form input array into a PHP array

I have a form like the one below which is posted to contacts.php, and the user can dynamically add more with jQuery.

<input type="text" name="name[]" />
<input type="text" name="email[]" />

<input type="text" name="name[]" />
<input type="text" name="email[]" />

<input type="text" name="name[]" />
<input type="text" name="email[]" />

If I echo them out in PHP with the code below,

$name = $_POST['name'];
$email = $_POST['account'];

foreach($name as $v) {
    print $v;
}

foreach($email as $v) {
    print $v;
}

I will get something like this:

name1name2name3email1email2email3

How can I get those arrays into something like the code below?

function show_Names($n, $m)
{
    return("The name is $n and email is $m, thank you");
}

$a = array("name1", "name2", "name3");
$b = array("email1", "email2", "email3");

$c = array_map("show_Names", $a, $b);
print_r($c);

so my output is like this:

The name is name1 and email is email1, thank you The name is name2 and email is email2, thank you The name is name3 and email is email3, thank you
