Csv file data (lineid and usernamme) on EC2 is inserted into RDS with PHP.
I would like to confirm that the usage of baindvalue is correct.
As a premise, the csv file has been read, and the contents have been confirmed by debugging.
$file [0] contains lineid and $file [1] contains username.
The connection to DB has also been completed.
And when you run the code
"PHP Parse error: syntax error, unexpected end of file in /home/ec2-user/index.php on
line 40 "will come back.

I looked up and used it, but it's a good thing, but I can't use it.
Is it correct to recognize that the variable that stores the value I want to put in the second subtraction number of bindvalue?

I would appreciate any advice.

Read CSV file
try {
    $file = new SplFileObject ('/ tmp/winneyuser.csv');
    $file->setFlags (SplFileObject :: READ_CSV);
} catch (RuntimeException $e) {
    throw $e;
}
Code

DB connection
try {
        $pdo = new PDO (
            'mysql: host = *********,
            '************',
            '***************',
            [
                PDO :: ATTR_ERRMODE =>PDO :: ERRMODE_EXCEPTION,
                PDO :: ATTR_DEFAULT_FETCH_MODE =>PDO :: FETCH_ASSOC,
            ]);
} catch (PDOException $e) {
        header ('Content-Type: text/plain;charset = UTF-8', true, 500);
        exit ($e->getMessage ());
 }
 header ('Content-Type: text/html;charset = utf-8');

Import to DB using

bindvalue
$line_id = $file [0];
$username = $file [1];
    foreach ($file as $files) {
        $stmt = $pdo->prepare ("INSERT INTO users (line_id, name) VALUES (: lineid,: username)");
        $stmt = $pdo->prepare ($sql);
        $stmt->bindValue (': line_id', $line_id, PDO :: PARAM_STR);
        $stmt->bindValue (': username', $username, PDO :: PARAM_STR);
        $stmt->execute ();
        $pdo->commit ();
    }
