Make a list form php string

I have this code that write inside the variable $products a string of products name:

$products = '';
foreach($order->pad_products as $product) $products .= " $product->title";

When I print $products inside a HTML email body and send the email with PHP, in this case, I sand $msg, I see the name of the products all in one line.

$msg = "
  <html>
    <head>
      <style type='text/css'></style>
    </head>
    <body>
      <h1>Sent!</h1>
      <p>$name thank you</p>
        $products
    </body>
  </html>";

How can I make a list of these products? and, can I delete one of these?

Answer

To display them as a list, you simply have to create a list using HTML:

<?php
echo "<ul>";
foreach($order->pad_products as $product) {
    echo "<li>" . $product->title . "</li>";
}
echo "</ul>";
?>

Alternative, applying to your current code

<?php
$products = "";
foreach($order->pad_products as $product) {
    $products .= "<li>".$product->title."</li>";
}
$msg = "
<html>
<body>
  <h1>Sent!</h1>
    $products
</body>
</html>";
