In MYSQL, how to insert data by PDO binding variables?

  mysql, question

For example, my SQL statement is

INSERT INTO `man_db_write`.`man_articles` (`title`,`content`,`created`) VALUES (:0_title,:0_content,:0_created),(:1_title,:1_content,:1_created)

Then I bind variables in PHP

$stmt->bindParam(':0_title','title 1');
 $stmt->bindParam(':0_content','content 1');
 $stmt->bindParam(':0_created','1418103633');
 $stmt->bindParam(':1_title','title 2');
 $stmt->bindParam(':1_content','content 2');
 $stmt->bindParam(':1_created','1418103635');
 $stmt->execute();

Is the method of inserting data in batches scientific?
