passing multidimensional array from form in php

I have a bit of a headache here. My problem is as follows. I have three sites that I e-mail items to, all three sites have a couple of default mail addresses. so on my form i create inputs with the existing addresses and allow the user to create more dynamically. i might end up with the following

site 1 - address 1
site 1 - address 2

site 2 - address 1
site 2 - address 2
site 2 - address 3

etc

my inputs look like <input type="text" name="email[]"/>

i need to pass the site identifier and the inputted address to my php script and loop through it to add the list to the database

You can specify the array key and also make it two dimensional:

name="site[1][]"
name="site[1][]"
name="site[2][]"
name="site[2][]"

Then loop through and use key and value:

foreach($_POST['site'] as $site => $addresses) { // $site is the number and $addresses is an array
    $address_list = implode(',', $adresses);     // or loop $addresses or whatever
}

There are a lot of possibilities depending on how is easiest to structure and access it in your particular case.

Let's assume a basic form like this:

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

Your email fields would appear in PHP as the following:

$_POST['email'][0]
$_POST['email'][1]

As you can see, all email fields are neatly stored into the array $_POST['email']. PHP Does this automatically when appending [] to your input field names.

You can also nest them even deeper:

<form method="post">
    <input type="text" name="email[1][]" />
    <input type="text" name="email[1][]" />
    <input type="text" name="email[2][]" />
    ...
</form>

Now they would show up in $_POST['email'][1][...], $_POST['email'][2][...] and so on.
