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