How to use mysqli prepared statements?

by

From the mysqli::prepare docs:

The parameter markers must be bound to application variables using mysqli_stmt_bind_param() and/or mysqli_stmt_bind_result() before executing the statement or fetching rows.

bind_param docs.

i.e.:

$name="one";
$age  = 1;

$stmt = $mysqli->prepare("INSERT INTO users (name, age) VALUES (?,?)");

// bind parameters. I'm guessing 'string' & 'integer', but read documentation.
$stmt->bind_param('si', $name, $age);

// *now* we can execute
$stmt->execute();
