for mySQL, the table would look like...
CREATE TABLE polls(
pollID INT NOT NULL AUTO_INCREMENT,
ipAddress VARCHAR (50) NULL,
insertTime DATETIME NULL,
etc...
PRIMARY KEY (pollID)
);
===
the code would look like...
$statement = select pollID from polls where insertTime (now() - INTERVAL
1 HOUR); //see mySQL date time functions for a description of this
$result = mysql_query($statement);
$rowsReturned = mysql_num_rows($result);
if($rowsReturned){
print Sorry you already voted in the last hour;
}else{
insert into polls (ipAddress,insertTime) values ('$ipAddress',now());
}
P.S. - now() is a database function that will insert the time for you
(mySQL is usually -dd-mm hh:mm:ss)

MYSQL
Here is a sample of what I am doing
$ip = $_SERVER['REMOTE_ADDR'];
$time_now = mktime();
// open connection to database
$connection = mysql_connect($hostname, $user, $pass) or die (Unable
to connect!);
// get the IP and stored DB time
$query = SELECT ip_address, server_time
FROM stats
WHERE ip_address = '$ip';
$result = mysql_db_query($database, $query, $connection) or die
(Error in query: $query. . mysql_error());
$row = mysql_fetch_array($result);
$get_ip = $row['ip_address'];
$get_server_time = $row['server_time'];
// close connection
mysql_close($connection);
mysql_free_result($result);
if ($ip == $get_ip)
{
$connection = mysql_connect($hostname, $user, $pass) or die
(Unable to connect!);
$query=select * from stats where server_time 'now()- 1
hour' and ip_address = '$ip';
$result = mysql_db_query($database, $query, $connection) or
die (Error in query: $query. . mysql_error());
$row = mysql_fetch_array($result);
$get_ip2 = $row['ip_address'];
$get_server_time2 = $row['server_time'];
// close connection
mysql_close($connection);
mysql_free_result($result);
if ($get_server_time2)
{
echo Sorry cannot vote;
exit;
}
}

One question on this issue. What should I store in the database mktime( ).
time( )?
Jason Vincent wrote:
yeah - the mktime function is returning unix style time (seconds since
1970) which is why only the last few numbers are changing. I would
recommend letting the database decide who is able to submit... i.e.
select * from database where lastSubmitDate 'now()- 1 hour' and IP =
'$ipaddress'
if there is a returned record from the database, you know that this
person has made a submission in the last hour. Otherwise, let them
submit again
Obviously, you will need to figure out the sytax for the now() -1 hour
part depending on your database.

Subject: [PHP-DB] Difference in time
Hello all,
I am fighting a time issue(don't we all). I have a online poll set up.
I need a way to stop a person from submitting more than once an hour.
As of now I have the time .. mktime(
) .. being stored in a database along
with the users IP.
I want to be able to say if 1 hour has passed from the time .. mktime(
) .. that is stored in the db they can vote once again. This also has
to account that if someone goes to the poll tomorrow at the same time
(same
hour) the script knows it's a different hour and different day.
Scenario: I submit to the poll at 12:00 PM, one hour from now will be
1:00 PM and I can submit again. Now lets say it's 12:00 PM the next
day. The database stored time will say 12:00 PM of the day before, It
will not let me submit because it thinks that it has to be at least
1:00 PM before I can submit again. Which is wrong.
I was trying to use the mktime( ) function but it keeps giving me
these results.(( 1033578795 )) The last few numbers change but the
first few (that as suppose to be the hour) does not change? mktime(int
hour, int minute, int second, int month, int day, int year). How can I
use this mktime( ) function to do what I need it to? Am I going
