php - PDO syntax error for SELECT query

I have a basic query which gets all fields and exports the file but it keeps giving me an error. My code looks like this:

$array = ['users'];

foreach($array AS $i){
        $file = $i.'.sql';

        $stmt = $pdo->prepare("SELECT * FROM ? INTO OUTFILE ?");
        try {
            $stmt->execute(array($i,$file));
        } catch (PDOException $e) {
            $log .= $e -> getMessage().'........ \n ';
        }
}
Copy code

I keep getting this error how ever:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''users' INTO OUTFILE 'users.sql'' at line 1.

What is the correct syntax for this ?
