如何让PDO Fetch()以字符串形式返回(How to get a PDO Fetch( ) to return as string)

如何让PDO以字符串而不是数组的形式返回数据? 我不知道这是可能的,所以如果没有的话,是否有办法将数组转换为字符串后处理?

我的代码返回字符串是:

$result = $stmt->fetch(PDO::FETCH_ASSOC);
print_r($result);

我尝试了不同的提取类型,例如FETCH_CLASS FETCH_OBJ


How can I get a PDO to return the data as a string not an array? I am not sure this is possible so if not is there a way to convert the array to a string after it has been processed?

My code which is returning the string is:

$result = $stmt->fetch(PDO::FETCH_ASSOC);
print_r($result);

I have tried different fetch types such as FETCH_CLASS FETCH_OBJ

最满意答案

你可以这样做:

echo $stmt->fetchColumn();    

要么:

$result = $stmt->fetch(PDO::FETCH_ASSOC);
echo $result[0];

You can do it like this:

echo $stmt->fetchColumn();    

Or:

$result = $stmt->fetch(PDO::FETCH_ASSOC);
echo $result[0];
