Hi to all,
I'm new to PHP. I'm trying to retrieve data from a database, but I just
want to retrieve one record at a time and go through to the next
records by click next record. I know how to retrieve all record by
using the
mysql_fetch_array, but I'm having problems to select one record at
time. Any idea?
Thanks in advanced

Nato, you can use the MySQL LIMIT feature as part of your SELECT statement
to accomplish this.
$SQL = SELECT * FROM my_data LIMIT 0, 1;
The result that you get with mysql_fetch_array is only one record, the
first record that the database returned from the SELECT statement.
When your user presses NEXT, you would execute:
$SQL = SELECT * FROM my_data LIMIT 1, 1;
The second number is the number of records to limit by, in your case only
one at a time. The first number is the index of the record that you want
to have returned by the database. This number would be a variable in your
case that would increment by one when they press NEXT and decrement by one
when they press PREVIOUS.
Hope that helps you out.
Josh
