How do i echo multiple lines of input with this code?

I want the user to enter an animal and it go to the line below their previous input.

    <!DOCTYPE html>
<html>
<head>
    <title> Will Proj. 2</title>
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <h1> Animal Form</h1>

<form action="" method="post">
  Enter animal:<br>
  <input type="text" name="animal"><br><br>
  <input type="Submit" value="Add Animal">
</form>

<?php
function display()  {
    $animal = $_POST['animal'];
    echo "$animal <br>";
}
if(isset($_POST['animal'])){
    display();
}
    ?>

</body>
</html>

It currently only displays 1 line at a time and refreshes the line with new input.

<?php

session_start();

if (!isset($_SESSION['animals']) && $_POST['animal']) {
   $_SESSION['animals'] = $_POST['animal'].'<br>';
} elseif (isset($_SESSION['animals']) && $_POST['animal']) {
   $_SESSION['animals'] .= $_POST['animal'].'<br>';
}

?>

<!DOCTYPE html>
<html>
<head>
  <title> Will Proj. 2</title>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
   <h1> Animal Form</h1>
   <form action="" method="post">
     Enter animal:<br>
     <input type="text" name="animal"><br><br>
     <input type="Submit" value="Add Animal">
   </form>

   <?php if (!empty($_SESSION['animals']) { echo $_SESSION['animals']; } ?>
