bindParamPDOStatementthe way you are, PDO of course you can't find it.

PDOStatementIs PDO::prepare() the return object, do not know where you go to see the code, the PDO object name $stmt , and do not get ->prepare() back PDOStatement .

$pdo = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);//先新建一个PDO$pdo->->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);//开启PDO的报错$sql = 'SELECT * FROM article WHERE id > ?';try{    $stmt = $pdo->prepare(sql);//返回的statment的值赋给$stmt    $stmt -> bindParam(要绑定的占位符的位置, 要绑定的变量 [, 数据类型]);//bindParam()是$stmt的方法而不是$pdo的方法    $stmt -> execute();//执行sql语句} catch (PDOException $e) {        echo 'Execute SQL failed: ' . $e->getMessage();        exit();    }

It should be like this.
