Adding a variable to an array using a Post Form

Question

I want to add my $_POST variable to my array every time I submit a name. With this code it empties the array every time I use the Form. How should I do this if I want to add to the array everytime I submit a name?

<?php
    $array = array();

    if (isset($_POST['name'])){
        $new_name = $_POST['name'];

        array_push($array, $new_name);
    }

    print_r($array);
?>

<form action="index.php" method="POST">
    <input type="text" name="name">
</form>

See you need something that will remember what $array was, even after a refresh. So either you would need to save it in a database / cookie.

Here is an example using a session ($_SESSION).

<?php
session_start();
if(!isset($_SESSION['names'])){
    $_SESSION['names'] = array();
}
if (isset($_POST['name'])){
    $_SESSION['names'][] = $_POST['name'];
}
foreach($_SESSION['names'] as $name){
    echo $name . '<br>';
}
?>

<form action="index.php" method="POST">
    <input type="text" name="name">
</form>

If you don't understand anything, please do ask.

So how would I destroy this array if someone closes the site? I'm making a system in which the site chooses 3 people at random. The persons are provided by the person. – Giel Beuzel Jan 01 '16 at 22:17
The session is unique to each browser, it will not be visible to other users. – Anees Saban Jan 01 '16 at 22:22
Do you need it to be? – Anees Saban Jan 01 '16 at 22:24
OK! What would be the best way to only display the names and not the array(3) { [0]=> string(4) "Steve" [1]=> string(4) "Bill" [2]=> string(5) "Mark" } – Giel Beuzel Jan 01 '16 at 22:25
No it needs to be personal. – Giel Beuzel Jan 01 '16 at 22:25
A foreach loop, I will update the answer for you. - Updated – Anees Saban Jan 01 '16 at 22:25
Thanks! It works! What is the difference between array_push and what you are using right now? – Giel Beuzel Jan 01 '16 at 22:30
