致命错误:调用未定义的方法 mysqli_result::fetch_all()

我在 Ubuntu 10.04 中遇到 PHP 问题.当我尝试使用 mysqli_result::fetch_all 时出现此错误:

调用未定义的方法mysqli_result::fetch_all()

但是，它可以在 Windows XP 中运行.

代码:

$result = $this->dbh->query('SELECT [...] ');返回 $result->fetch_all(MYSQLI_ASSOC);

我不想在循环中使用 fetch_assoc，因为我将结果发送到另一层进行处理.

我使用的是 PHP 5.4.4.并使用 php -m |grep mysql mysqlnd 模块它没有出现.我该如何安装它?这可能是问题吗?

解决方案

mysqli_result::fetch_all() 需要 MySQL Native Driver (mysqlnd).

您可能会错过它.

mysqli fetch_all() 不是有效函数?

I have problems with PHP in Ubuntu 10.04. When I try use mysqli_result::fetch_all this error appears:

Call to undefined method mysqli_result::fetch_all()

However, it works in Windows XP.

The Code:

$result = $this->dbh->query('SELECT [...] ');
return $result->fetch_all(MYSQLI_ASSOC);

I don't want to use fetch_assoc with a loop because I send the result to another layer for processing.

I'm using PHP 5.4.4. and with php -m | grep mysql the mysqlnd module it doesn't appear. How can I install it? Could that be the problem?
