mysqli fetch_all()不是有效函数? [英] mysqli fetch_all() not a valid function?

问题描述

由于有了答案，我发现我无法使用fetch_all()，因为我在PHP 5.2.17-fetch_assoc中使用了while循环.

Thanks to the answers I have figured out that I am unable to use fetch_all() because i am using PHP 5.2.17 - fetch_assoc with while loop worked.

我正在使用的功能fetch_all再次出现此错误:

The function I am using fetch_all is coming back with this error:

致命错误:在以下位置调用未定义的方法mysqli_result :: fetch_all()

Fatal error: Call to undefined method mysqli_result::fetch_all() in

$mysqli = new mysqli($host, $username, $password, $database);
$query = "LONG QUERY that works, tested in phpmyadmin"
$result = $mysqli->query($query);
$result->fetch_all(); or  $mysqli->fetch_all() tried both
mysqli_fetch_all() was already tried.
$mysqli->close(); 

我能够连接到数据库，并且已经拉出了单行.当我将查询放入PHPMYADMIN时，我会返回5行.

I am able to connect to the DB and I have pulled single rows. When I place the query in PHPMYADMIN I get 5 rows back.

此功能是否还有效?有没有办法我可以将数据自己放置到一个assoc数组中?

Does this function even work? Is there a way I can place my data into an assoc array on my own?

推荐答案

此功能自PHP 5.3.0起可用.可能是您的版本较旧.改为使用fetch_assoc().

This function is available since PHP 5.3.0. Possibly your version is older. Use fetch_assoc() instead.

while ($row = $result->fetch_assoc()) {
    // do what you need.
}
