[PHP-DB] dbx question - specifying a port for pgsql
Hello, We have been using dbx here at work, and it seems that it could be a very useful tool, since we use several DBMSs. However, on one of our servers, we have to run Postgres on a port other than 5432. After reading the documentation and finding nothing there, I took a look at the source, and noticed that the port is hardcoded. I was wondering if there are any plans to allow the spefication of a port via the dbx_connect funtion. It looks to me that in dbx_mysql.c, you can use the MySQL host:port/host:socket syntax. Is there any possibility that this syntax or a variation of it could be used throughout dbx?

Re: [PHP-DB] [PHP-MySQL] lock a record of MySQL from PHP
1. Check MySQL syntax for locking a record 2. Build the query to do that, assigning it to something like $qry 3. mysql_query( $qry ) 4. Check for results HOWEVER - given that the web is a stateless environment, and a user can just close a browser, or walk away, or whatever, are you SURE you want to lock a record? An awful lot of db work can be done w/o express locking of records. You get an implicit lock on an UPDATE or INSERT. I've not checked the MySLQ docs, but the classic way to see if a record is locked is to attempt a lock. I'd suggest reading up on the pro's and con's of locking, either in the MySQL docs or in a general book on SQL. Hope this helps - Miles Thompson At 12:11 PM 9/27/2002 +1000, Michael Wai wrote: I'm a newbie of PHP and MySQL. Would anyone tell me that how to lock and unlock a record of MySQL from PHP?

SV: [PHP-DB] Current row of query
Actually you dont need to keep track of the row number. Yoy could just
alternate the two colors like this:
while ( $row = mysql_fetch_array($result) )
{
$bgCol = ( $bgCol == #EADBC6}?#EFE1CE:#EADBC6;
echo ..;
}

Thanks, im currently doing something similar to this but I was wondering if
there was an already defined variable that i could use rather then have to
create a value and increment it myself. I guess am being picky, but was just
curious as im new to php.
This is how im currently doing it...
$rowNum = 0;
while ( $row = mysql_fetch_array($result) )
{
$rowNum++;
if ($rowNum % 2) { $bgCol = #EADBC6; } else { $bgCol = #EFE1CE; }
echo ..;

[PHP-DB] Flush database
I am storing IP addresses in a database, but after an hour has passed I want to delete all the IP addresses from that database. I want to do this based on the server time. Example.. Someone comes to my web page, I store their IP address in my database. So now I write a PHP script that says if that IP returns to my page within an hour, they can't view my page. If they come back after an hour has passed they can view the contents of that page. but only after an hour has passed. Can anyone help me with the syntax or functions that will clear the database after an hour of waiting has passed? Is this possible?

Re: [PHP-DB] Dates
May I recommend setting the field type to INT, and just using timestamps? That's what I usually do, then you can manipulate things however you want. Much more convenient than the date style type I think. Looking at how the MySQL docs talk about the DATETIME field, I bet the database is doing just that, but converting for you. If you use the PHP date/time functions instead to convert you have a lot more control. -Micah At 09:38 PM 9/27/2002 +0100, Steve Vernon wrote: Hiya, I am doing a database of things that have dates, some I know the month and year of, some I only know the year.

why not simply store the server time at log in in the DB after a successful log in together with the IP address; and at the next log in request perform a SQL time difference comparison?

Re: [PHP-DB] Flush database
How about writting the IP address to the database with a timestamp, then when a matching IP address arrives you view the timestamp and if it has been more then a hour, they can view the page, which would force you to update the timestamp. Of course you would probably need to write a stand-alone (i.e. non-web) php script that would act as a cron job to clean out the database periodically, whatever period you define (depending on traffic and size of DB). -Brad wade wrote: I am storing IP addresses in a database, but after an hour has passed I want to delete all the IP addresses from that database.

Re: [PHP-DB] Flush database
First make sure that you are storing the IP and the time it was saved in the database. Then I would have 3 queries: 1) a query to see if the IP address is in the database and less then an hour old. 2) a query to save the IP and time into the database 3) a query to delete all entries over 1 hour old. Then when you get a new visitor see if the IP address is in the database and is not less then 1 hour old. Once it clears that test, save the IP and time, then always run the delete query to clear out entries. If you have a lot of traffic to your site you are going to generate a lot of database hits. Good luck.

Re: [PHP-DB] Flush database
Sounds like we are all on similar pages with timestamping, but if you issue a delete query every time the page is viewed it could create some sub-par performance based on number of hits. i.e. if the site gets 100 hits in the first 10 minutes of operation, it would issue delete logic and queries 100 times, but since they are all *new* the logic would not really do anything, right? So, depening on what kind of traffic you plan to generate a cron job may be your best bet, if you plan to generate a whoel bunch, you may even need to kick it off every hour. -or- you could use this logic, but store in a different table a timestamp for last delete and every time view that timestamp, and if more then a hour has passed, then go ahead with your database clean-up routine. -Brad Jim Hunter wrote: First make sure that you are storing the IP and the time it was saved in the database.

[PHP-DB] Flush database
So how would one compare the timestamp?
how would you write
if timestamp is greater than timestamp + 1 hour
{
Ok to view page
run query to update that IP to new timestamp -- I think this will
be better than a delete statement
}
else
{
Can't view page
}
I know you will have to compare the timestamps. the one in the database
against the current hit.
How would one do this comparison?

Using UNIX timestamps:
if (time() - $timestamp mktime(1,0,0,0,0,0)) {
// Difference it greater than one hour. Perform rejection
code here
} else {
// Difference is one hour or less. Perform acception code here.
