echo mysql_error();
echo "当前的MYSQL版本是:".mysql_get_server_info()."<br>";
$db = mysql_list_dbs($link);
while($row = mysql_fetch_object($db)){
$db_name = $row->Database;
echo "<b>数据库：".$db_name."</b>"."<br>";
$db_table = mysql_list_tables($db_name);
while($row = mysql_fetch_row($db_table)){

$result = mysql_query("select * from $row[0]");
$flags=mysql_field_flags($result,0);
echo "<pre>
$row[0] : $flags <br>
</pre>";

}
?>
