这里其实并不需要其它的什么函数来支持,只需要使用MYSQL提供的一些SQL语句就可以了。

  这里为了简单起见,以MYSQL的系统表USER为例,取出SELECT_PRIV这一列的所有可能值。

  方法:SHOW COLUMNS FROM table_name LIKE enum_column_name

  小写的部分需要根据你的情况改变。

  程序:

  $connect_hostname="localhost";
  $dbname="mysql";
  $connect_username = "root";
  $connect_pass ="";
  $connect_id = mysql_connect($connect_hostname, $connect_username, $connect_pass);
  mysql_select_db($dbname);
  $query="show columns from user like 'select_priv'";
  $result=mysql_db_query($dbname,$query);
  $enum=mysql_result($result,0,"type");

  echo $enum."
";
  $enum_arr=explode("(",$enum);
  $enum=$enum_arr[1];
  $enum_arr=explode(")",$enum);
  $enum=$enum_arr[0];
  $enum_arr=explode(",",$enum);
  for($i=0;$i 
  echo $enum_arr[$i]."
";
  }
  ?>
