Is question mark really need when select all row in prepared statement?

I wonder if I still need question mark if I don't want to specify any row. Because bind_param needs it.

$zr="0";

$stmt=$mysqli->prepare("select * from products_db where not prd_id=?");

$stmt->bind_param("i",$zr);//can I skip this line or what?

I search everywhere but there's no such a thing. Once I tried without ? it errors without reason. I might be typo error, something?

FYI, no program ever "errors without reason". If you can't see the errors, it just means your environment is not configured to show them. See How to get useful error messages in PHP? and How to get MySQLi error information in different environments

If you don't need to bind any parameters, you can use mysqli::query()

$result = $mysqli->query('SELECT * FROM products_db');

This both prepares and executes the SQL provided but offers no way to safely bind parameters.

This is roughly equivalent to...

$stmt = $mysqli->prepare('SELECT * FROM products_db');

$result = $stmt->execute();

which you can also use.

Note there are no positional parameters (ie ?) and therefore, no need to use mysqli_stmt::bind_param().
