[PHP] Sessions don't work?
Hewwo all, (please be so kind as to CC me in replies as I am not a subscriber to this mailing list (yet)) The following code snippet always outputs "You have visited this page 1 times!". What am I doing wrong? " " I realise I could use $_SESSION, and I actually prefer it, but I have to write code that will run on 4.0.6.

[PHP] Re: Sessions don't work?
I'd like to post a follow-up to my previous message on this subject.
Please still CC me when replying, thanks.
New test code:
"
");
echo(sprintf("You have visited this page %d times!", $counter2) . "");
echo(sprintf("You have visited this page %d times!", $_SESSION['counter3']) . "");
?>
"
Tried these on PHP 4.0.6 (register_globals = On):
- counter: doesn't work
- counter1: works
- counter2: doesn't work (to be expected)
PHP 4.2.2 (register_globals = Off):
None of the counters work; same when register_globals = On
I'm really puzzled by this; could someone please point me in the right
direction?

[PHP] Lazy evaluation?
Hey all, Does PHP support lazy evaluation?

[PHP] PHP for shell scripting: weird error.
Hey all, When running PHP scripts from the command line, I get this error: "Content type: text/html PHP Fatal error: Unable to start session mm module in Unknown on line 0" The script doesn't run, or so it seems. I also get this error when I run generic stuff such as 'php4 --help', or just 'php4 -q'. The script in question is this (though I hardly think it matters): #!/usr/bin/php4 -q Does anyone know what is going on? Searching the archives for the error string turned up nothing. I'm running PHP v4.0.7RC3 (from package php4-cgi) on Linux 2.4.10-ac11. Distribution debian unstable.

[PHP] Weird database stuff.
Hey fellow PHP-codemonkeys. :)
Let me start by laying out some facts:
SELECT e.NAME AS customer, g.NAME AS driver_lastname, g.FIRSTNAME AS
driver_firstname, $CommonSQL, COUNT(g.NAME) AS number FROM ENTITY e, ENTITY
g, EXPERTISE_FILE f, DAMAGE_CASE d WHERE (f.CUSTOMER = '$CustomerID') AND
(e.ID = f.CUSTOMER) AND (g.ID = f.DRIVER) AND (d.OWNER_EXP_FILE = f.ID) AND
(f.DATE_REPORT BETWEEN '$StartDate' AND '$EndDate') GROUP BY e.NAME, g.NAME,
g.FIRSTNAME
The query above is one of the statistics gathering queries in my application.
This one will run flawlessly.
If however I add this condition: "AND (f.DRIVER = '$DriverID')" before "AND
(g.ID = f.DRIVER), the script will eat all CPU and RAM (and eventually swap
aswell) on my PowerEdge 2500SC.
If I run both queries from inside psql (I use PostgreSQL), they -both- (!)
complete within split seconds...
If I leave set_time_limit() on the default of 30 secs, my script will time
out somewhere around these lines (though it seems like coincidence...):
function CalcDenied
(
$Requested,
$Agreed
)
{
$Denied = $Requested - $Agreed;--> Timeout here
if ($Denied < 0) --> Sometimes here
{
$Denied = 0;
}
return $Denied;
}
To me, this does not seem to make any sense, especially since the first query
(without the additional condition) runs fine, whilst it has to return many
more rows.
Does anyone have any idea what could be going on?
If you reply, please include a CC for me, as I am on digest (I don't have
time to sort through all the messages at work anyway, but I do contribute
from home. :)
Thanks

[PHP] PHP + Smarty question.
Using Smarty templates (it is my guess this question is valid for other template engines aswell), is there a way to pass an array to the template, then stuff it in a hidden form field and retrieve it in another PHP source file as an array? is_array() does not seem to detect the object is an array, and thus my code creates it anew. Basically what I am trying to do is add new stuff to the array, after it has been passed to the template and back into the script.

You could check if it has been set by doing:
if (isset($month))
or even
if ($month)
(I'm not 100% sure about the last one, though..)

Go over your results like this instead:
while ($row = mysql_fetch_row($result)) {
echo $row['listnum']; // displays 'listnum' field
echo $row['officephone']; // etc...
}
(I've assumed your syntax for the mysql_fetch_row() function, I haven't used
it in a while (use PostgreSQL myself)).

Hey there Chris, One way to do it is to store a timestamp in your database whenever a user logs on. Then every night or so, you run a cron-job (assuming you are on a UN*X sysem. Windows will probably have something similar that I'm not familiar with) that checks the timestamps and sends mails to every user that hasn't logged in for 30 days. If you have PHP compiled to an executable (i.e. you can run scripts on the command line), then your cron-job can just use a PHP script, otherwise I would recommend Perl. ad. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I've used this code for calling base class constructors. These ofcourse have
different names, while your functions are both called the same. I don't think

[PHP] Writing to two tables in 1-N relationship.
I have two DB tables that are in a 1 - N relationship. I need to enter data once in the 1-side, and then many times data on the N-side. (For those who like it less abstract: The 1-side is a table with data about a car (frame number, brand + type, and a carrier), the N-side has records about damages found on that car after transport) I'm a little bit confused about how to deal with this: - After every data input, write the stuff away to a temp text file, and when all input is done, write that text file at once to the database. - Store the data in arrays, and pass them on between runs of the script as part of the URL (but I could run out of space?) - A better way that I don't see? One thing is for sure, and that is that the data needs to be written to the DB in one go (so as to be able to use transactions effectively (in PostgreSQL)). Can anyone advice? Someone must have been in this position before. :) I hope I explained the problem ok, I tend to get carried away.

I'd say there are 2 solutions:
1) Set the default value in the dropdown box to '%'.
2) Just set $cat to whatever you want, when it is 'x'
if ($cat == 'x')
{
$cat = '%';
}
