First off, your query looks wrong, I believe it should be

"SELECT admin_name.admin_name, admin_name.admin_lastname, admin_name.admin_creattime,
        admin_detail.admin_pass, admin_detail.admin_phone, admin_detail.admin_email, admin_detail.admin_gender
FROM admin_name,admin_detail "

Then to figure out how to access it, write the following line within your while loop

var_dump($row);

You will either see that you need to reference the column names as $row[‘admin_name.admin_name’] or you may still be able to use $row[‘admin_name’] (I think the later will still be accurate).

thanku frnd it helped me when i use index number at the place of $name = $row[‘admin_name’]; than it works but if i do $name = $row[‘admin_name’] this again give the same error

Something that you need to keep in mind is that the mysql_* extension is deprecated as of version 5.5 of PHP, you should really be migrating over to either the mysqli_* extension or to PDO

Did you update your query and perform the var_dump as I stated? The var_dump will give you an output that tells you the key name to use.
