SQLSTATE[HY093] 错误但数组长度相同
SQLSTATE[HY093] error but arrays are the same length
有一个问题，PDO 给我一个异常，说参数未定义。但是，我提供给它的两个数组肯定具有相同的长度和键，所以有什么问题吗？
您可以在下面看到函数，然后是更新查询，然后是正在发送的数组。 52是每部分的长度，下面是异常文本。
public function query($sql,$data,$read) {
if (!($query = $this->connection->prepare($sql))) { exception(implode(' ',$query->errorInfo()),intval($query->errorCode())); }
if (!($query->execute($data))) { exception(implode(' ',$query->errorInfo()),intval($query->errorCode())); }
if ($read) { $result = $query->fetchAll(PDO::FETCH_ASSOC); $this->count_reads++; } else { $result = $query->rowCount(); $this->count_writes++; }
$query = null; return $result;
}

我似乎已经缩小了它的范围 - 仅限 PDO returns 如果其中一个键包含像 :test__variable-hyphen 这样的连字符，则会出错。为什么不允许？
许多特殊字符（例如 +、-、逗号...）不是合法的列名，除非您将列名括在 bactics 中：test__variable-hyphen.
否则，它看起来太像减法了。
