// object(mysqli_result)#3 (5) { // ["current_field"]=> // int(0) // ["field_count"]=> // int(4) // ["lengths"]=> // NULL // ["num_rows"]=> // int(7) // ["type"]=> // int(0) // } 如果使用的 MYSQLI_STMT 的话,直接在 execute() 方法执行查询语句之后,就...
$stmt=$mysqli->prepare("select * from zyblog_test_user where username = 'kkk'");$stmt->execute();// 执行语句$result=$stmt->get_result();var_dump($result);// object(mysqli_result)#3 (5) {// ["current_field"]=>// int(0)// ["field_count"]=>// int(4)// ["lengths"]=...

object(mysqli_result)#2 (5) { ["current_field"]=> int(0) ["field_count"]=> int(4) ["lengths"]=> NULL ["num_rows"]=> int(1) ["type"]=> int(0) }代码如下: if(!empty($_POST['username'])):include_once './lib/fun.php';$username = trim($_POST['username']);...
