How to fetch assoc array while using mysqli prepare

How to fetch assoc array while using mysqli prepare

To make sure my database is secure I'm using prepare statements. Here is
my code:
//connecting to MySql database
$con=mysqli_connect("host","user","pass","dbname");
// checking database connection
if (mysqli_connect_errno($con)){
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$stmt = mysqli_prepare($con,"SELECT * FROM `table` WHERE emb=? LIMIT 1");
mysqli_stmt_bind_param($stmt, 's', $emb);
mysqli_stmt_execute($stmt);
mysqli_stmt_close($stmt);
Now I want to know how can I use ASSOC fetch array
$embInfo = mysqli_fetch_array($stmt, MYSQLI_ASSOC);
I want this so that I can just put something like below to get values
$embInfo['name']
and
$embInfo['email']
