php - 如何在 php 中显示表架构查询中的数组

Question

我有一个疑问

$qdrop=mysqli_query($connect,"select TABLE_NAME,create_time
      FROM INFORMATION_SCHEMA.TABLES 
      WHERE table_schema = 'purbalingga' 
      AND CREATE_TIME <='2016-10-07' and TABLE_NAME LIKE '2016%'");

还有一段时间来显示数组

while ($datadrop=mysqli_fetch_array($qdrop)) {
      echo $qdrop['TABLE_NAME'];echo"<br/>";
       }

但是我遇到了一个错误:

Fatal error: Cannot use object of type mysqli_result as array in E:\xampp\htdocs

Answer 1

替换:

while ($datadrop=mysqli_fetch_array($qdrop)) {
  echo $qdrop['TABLE_NAME'];
  echo"<br/>";
}

与:

while ($datadrop=mysqli_fetch_array($qdrop)) {
  echo $datadrop['TABLE_NAME'];
  echo"<br/>";
}

$qdrop 仅保存查询，但 $datadrop 是将结果保存在数组中。
