mysqli fetch_all() 不是一个有效的函数?

2021-12-25 00:00:00 php mysqli

感谢答案，我发现我无法使用 fetch_all() 因为我使用的是 PHP 5.2.17 - fetch_assoc> 使用 while 循环工作.

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.

我正在使用的函数 fetch_all 返回此错误:

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

致命错误: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我已经提取了单行.当我将查询放在 PHPMYADMIN 中时，我得到 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.

这个功能还能用吗?有没有办法可以自己将数据放入关联数组中?

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

该函数自 PHP 5.3.0 起可用.可能你的版本比较旧.改用 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.
}
