所以我有一个PHP函数来更新数据库中的2列.它看起来像这样:

$fields = array("firstname" => "Joe", "lastname" = "Dunno");

$stmt = $connection->prepare("UPDATE users SET firstname = :firstname, lastname = :lastname WHERE user_id = :user_id");

foreach ($fields as $key => $value)
{
    $stmt->bindParam(":" . $key, $value);
} 

$stmt->bindParam(":user_id", $user_id);

但是当我出于某种原因执行语句时,它喜欢将名字和姓氏都更新为Dunno而不是Joe和Dunno.

我试着回声$key并且$value正确打印出来.

出于一些奇怪的原因,如果我使用它for循环它正常工作.

for ($fieldsKeys = array_keys($fields), $x = 0; $x < count($fields); $x++)
{
    $stmt->bindParam(":" . $fieldsKeys[$x], $fields[$fieldsKeys[$x]]);
}
