?>推荐答案
我会从这样的事情开始:
I would start with something like this:
$con = new PDO( "mysql:host=".$dbHost.";"."dbname=".$dbName, $dbUsername, $dbUserPassword);
$con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "DELETE FROM `table` WHERE id = ?";
$q = $con->prepare($sql);
$response = $q->execute(array($id));
