如何知道php脚本中的名称是指mysql表还是mysql视图

I can select all tables in a database like this

我可以像这样选择数据库中的所有表

$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
  $tables[] = $row[0];
}

And following code populate $return variable which can be used to backup the database.

后面的代码填充$return变量，可以用来备份数据库。

  foreach($tables as $table)
  {
    $result = mysql_query('SELECT * FROM '.$table);
    $num_fields = mysql_num_fields($result);

    $return.= 'DROP TABLE IF EXISTS '.$table.';';
    $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
    $return.= "\n\n".$row2[1].";\n\n";

    for ($i = 0; $i < $num_fields; $i++) 
    {
      while($row = mysql_fetch_row($result))
      {
        $return.= 'INSERT INTO '.$table.' VALUES(';
        for($j=0; $j<$num_fields; $j++) 
        {
          $row[$j] = addslashes($row[$j]);
          $row[$j] = ereg_replace("\n","\\n",$row[$j]);
          if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
          if ($j<($num_fields-1)) { $return.= ','; }
        }
        $return.= ");\n";
      }
    }
    $return.="\n\n\n";
  }

My database has two mysql views. Above code generates "INSERT INTO...." string even for mysql views which I need to avoid. So before starting the 'for loop' to generate "INSERT INTO.." values I need to check if $table is actually a mysql table or view. How to identify whether a name refers to mysql table or mysql view?

我的数据库有两个mysql视图。上面的代码生成字符串“插入....”甚至对mysql的观点,我需要避免。因此，在启动“for循环”生成“INSERT INTO.”值之前，我需要检查$table是否实际上是一个mysql表或视图。如何识别名称是指mysql表还是mysql视图?

SHOW [FULL] TABLES

The FULL modifier is supported such that SHOW FULL TABLES displays a second output column. Values for the second column are BASE TABLE for a table and VIEW for a view.

支持完整修饰符，以便显示完整表显示第二个输出列。第二列的值是表的基表和视图的视图。
