如何在字符串html代码的echo中提及关闭大括号的函数？

I'm trying to close this foreach function curly brace inside echo, while the function itself is outside of the echoed html code.

foreach ($_SESSION["shopping_cart"] as $product) {
echo

"<form class='info-confrim' action='includes/info.inc.php' method='post'>

    <input type='hidden' name='product-name' value=".$product['name'].">
    <input type='hidden' name='amount' value=".$product["quantity"].">
    <input type='hidden' name='total-price' value=".$product['price'].">

            ".}."

    <button class='submit-button' type='submit' name='info- 
submit'>SUBMIT</button>

 </form>";

I want the button to be outside for-each function so that it won't repeat itself but this method is not working at this time. I know I don't have enough knowledge and that's why I'm here.

This will probably work. This is another way of making for-each loop or any other statement ( if, while...) without curly brace

<form class='info-confrim' action='includes/info.inc.php' method='post'>

<?php foreach ($_SESSION["shopping_cart"] as $product): ?>

    <input type='hidden' name='product-name' value=".$product['name'].">
    <input type='hidden' name='amount' value=".$product["quantity"].>">
    <input type='hidden' name='total-price' value=".$product['price'].">

<?php endforeach; ?>

<button class='submit-button' type='submit' name='info-submit'>SUBMIT</button>

 </form>
