带有Htaccess的漂亮url在url中显示产品名称，但用id调用产品

我试着用htaccess做一些类似的事情。

http://www.domain.com/product/fussball-in-munich/

但是菜单导航的链接是这样的，

<a href="product.php?id=10">Fussball</a>

我将通过ID调用产品，但我想在url中显示产品名称，

我用我的htaccess，但不工作，我想。

RewriteEngine On
RewriteBase /dev
RewriteRule ^index'.php$ - [L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^angebot/([A-Za-z-'s0-9]+)$ /dev/product.php?product_id=$1 [NC]
Options +FollowSymlinks -MultiViews
RewriteRule ^(.+)('s|%20)(.+)$ /$1-$3 [R=301,QSA,L,NE]

 if (isset($_GET['product_id'])){
$product_id = strip_tags($_GET['product_id']);
getProductsById($product_id);

}

$query = "SELECT * FROM `product` WHERE id='$product_id'";
$result = $mysqli->query($query) or die($mysqli->error.__LINE__);
$count = $result->num_rows;
    if ($count === 1){
        echo "<div class='container mt50'>";
            while($row = $result->fetch_assoc()){
            echo '<strong>This Product has been found in the database </strong>' .$row['product_name'];

                }
                echo "</div>";

    }else{}
