Q1: When I set a cookie, is that cookie automatically called from *each* page on my website? Or, do I need to add the HEADER to each page where I want to call the cookie?

So, I can use Serialize / Unserialize to store Array information in my cookies? Using serialize/unserialize isn't a bad idea, but neither is setting two cookies in my opinion. I'd say take your pick, choose whatever's most comfortable for you. I'd recommend only looking at the username/password cookies if a PHP session hasn't been established though to save you from takeing a quick query to your DB for every hit on each page though.

Re: [PHP-DB] possible mysql_insert_id() conflicts ?

From mysql's manual:
The last ID that was generated is maintained in the server on a
per-connection
basis. It will not be changed by another client. It will not even be
changed if
you update another AUTO_INCREMENT column with a non-magic value (that is,
a value that is not NULL and not 0).
As each thread is using it's own connection there is no need to lock the
table.
... that should answer your question. No need to worry, just trust that
MySQL will handle it for you.

Re: [PHP-DB] Application-based locking with PHP?
So long as you keep any referencial integrity from being broken by two nearly simultaneous updates I don't really see much of a problem. If two users update a trouble ticket what's the big issue? Perhaps a notification could be displayed on the update confirmation page letting one of the user's know that somebody else updated it while they also did. Take a look at bugzilla -- it chugs along just fine it seems w/out any bug locking mechanism. Probably not the ansewr you were looking for, however if you're still hellbent on getting a real locking mechanism in place you may wish to take a look at SysV semaphores at http://www.php.net/manual/en/ref.sem.php. Overkill solution If you're familiar with using them in C you should be able to pick right up on it; if not then you may wish to consult manpages of whatever OS you're using (I assume *nix) for the C counterparts: man 2 semget man 2 semctl man 2 semop man 5 ipc man 3 ftok Even if you use them, which should be more trustworthy than DB locking, you end up with the problem of unlocking it after the user has exited. Perhaps you could use the shared memory functions to insert a timestamp at which the semaphore expires, store that stamp in session variable, then before the update compare the session variable with the value in shared memory. If they don't match they've lost their lock because they took too long to update and somebody else now has the semaphore and is in control of the update. Rather than lock on the ablitity to update the DB though you have to lock on the ability to look at and update the shared memory segment. I don't think PHP has an application-wide variable scope, so shared memory is probably your only option. And hey, if you're dealing with SysV semaphores anyway you might as well just do the whole thing in a SysV IPC style. :) /Overkill Solution If it's really -really- important, that's the only truly solid option I see. If it's not this important the I'd dump it, let people muddle with the same ticket at once and let them sort their differences out later.

One being the entire table being locked and two if the user just closes the webpage without exiting properly, the table would remain locked indefinately. So I'm trying to think of alternatives, one of which is using global variables to store table/record id's, and then evaluating the queries based on that information. So if John selects ticket # 5 and might be updating it, then when Bob attempts to select ticket #5, then the $id and $table variables would be checked against the variables stored when john placed his query, and bob would get a message saying that record #5 is locked or in-use by John and to try later.

Re: [PHP-DB] currency out of postgresql
While the proposed solution below may very well indeed work for this situation it's a far better practice to strip the variable down to known to be good values rather than known to be bad ones. Rather than strip $ and , marks from the variable it's far better to strip out anything other than 0-9 and the '.' character. In this given situation it may or may not have any advantage -- just a different paradigm; and one that often improves application security. Rather than think of what's disallowed think only of what is allowed. A recent example of this would be to follow the BugTraq postings on the Unicode directory transversal exploits of MS IIS toward the latter end of 2000. The patch was released to prevent certain attacks from coming through but it proved to be patch developed by somebody with rather elementary security skills. They preventyed only -known- attacks from working; workarounds surfaced within a day, if not hours. Eventually they put a competent coder on the job and things were fixed. But, like I said, this probably isn't a security issue here -- just one of robustness. The two are rather similar in practice though. As I said before, the original poster's idea may very well work 100% of the time, but I thought I'd take the opportunity to point out the difference. I posted a private reply to the orignal author that went something like this: Strip out anything except 0-9 characters (after formatting), add them, divide by 100 and reformat. I don't imagine any locale settings that would cause this to error. I don't mean to nit-pick at anybody here, that's my last objective. Just something to think about when coding. Admittedly I've done the exact opposite approach (stripping known bad vs. allowing known good) many times and have been burned because of it.

Re: [PHP-DB] Table display Driving me Crazy!
Looking at your code for the first row (I've cleaned it up a bit to make it
readable!):
?php
$numcols = 5;
for ($l = 1; $l = $numcols; ++$l) {
?
td width=139 class=ModNo bordercolor=#00
?php
echo $db-f(product_sku);
?
/td
?php
}
?
It should be pretty clear why you're getting the product just repeated 5
times across the row.
Your statement:
echo $db-f(product_sku); does not contain any reference to
variables thus it's essentially a constant. As far as I can make out
(your style of coding gives me a headache :)) the other loops suffer
from the same problem.
The whole block is wraped in a while ($db-next_record()) { ...} loop
actually. Now, I'm not sure if the next_record() method is setting an
internal member to the current record and returning TRUE/FALSE for
success, or if it's actually supposed to be returning a row.
I'm guessing the class is simply being mis-used. The code is reasonably
logical assuming next_record() is setting an internal member variable to
the current row... doesn't look like it is though.
I know with ASP/VBScript that there's a decent performance hit when you
jump from HTML to VbScript and back again... I would imagine though not as
severe the same also happens in PHP. Rather than stop the parser, print
out something small like a /td and start the parser back up it's
probably better performance wise to just use the 'echo' function (well,
keyword, I guess echo isn't a real function, print is though). Plus, it
makes your code more readable without all the ?php ? marks everywhere.

Re: [PHP-DB] URL checking
You could use fopen() to retreive the HTML of the page, then parse it taking your best guess at a 404 message. Not very robust though. It'd be much better to open up a socket to the site itself, then issue a HEAD /page here request. If the page is not found you'll have a line in the return result (should be the first line) which says HTTP/1.0 404 Not Found, then your Content-type: will come across and the actual HTML for the 404 page. You'll have to parse the domain name off the entire URL that's stored in your database which could be done by chopping off a leading http://; if any is provided, then split at the first / mark. Use the experimental socket() function (http://www.php.net/manual/en/function.socket.php) to make your connection and issue the HEAD request. Hope that helps...

Re: [PHP-DB] Warning: Page has Expired
POST is no more secure, realistically, than the GET method. Both pass data around in plain-text form. In a perfect world web browsers wouldn't cache pages which were POSTed to as the HTTP specification says. At least, that's my understanding of it. Browsers -are- free to cache GET'ed pages though, because logically if the URL is identical to the other one the same data will be returned. So, switching to GET makes sense, because so long as the URL is slightly different each time the browser won't cache the page. Of course, in the real world not all browsers were made to spec, and some cache POSTed pages. So, to the original poster: It seems like your page is doing the Right Thing... but your browser isn't.

Re: [PHP-DB] store an array in a mysqldb
Nothing comes to mind that isn't a bit of a hack really. You could try seperating the data with delimiters before putting it in, then splitting the data back up into an array at query time. You could setup some tables, one called 'arrays' and one called 'array_values. Arrays would pretty much be one column -- just the id. Array_values would be 4 columns (3 if order doesn't matter) with: array_value_id, array_id, value, sequence (optional). However, I should probably note last I knew PostgreSQL supports the insertion of arrays into a record natively... though I have never personally used it.

Re: [PHP-DB] Seperate Tables for Same Data?
I'd suggest only inserting data into the working table throughout the day, then on a nightly basis drop the index on the archived table, import the data from the working table into the archived one, re-create the index and clear out your working table. As time goes on that archived table is going to get huge and you don't want your DB trying to insert into something like that during production hours. Better off waiting for some downtime where you can batch the whole thing in there. Just my two cents.

Re: [PHP-DB] Last Modified question..
a) What kind of database is this? b) use fstat() to check the modification time on a specific file. c) You will have to modify permissions so that the user your web server runs as has 'read' permission on the file if you want to use fstat().

Re: [PHP-DB] br appear in Text file
If you're getting a literal br in the file then I'd have to say you're either typing one in the text box or have your HTML putting on in there for you w/out knowing it. If it's a new line or a carriage return in the file that's a different matter. When somebody submits data to you in a textarea or input type=text field their newline character will match that of their OS. For a Win32 computer this is a two character combination, a carraige return (ASCII #13) and a line feed (ASCII #10). For a Unix/Linux machine it's just a line feed (ASCII #10), and for a Mac computer you get just a carriage return (ASCII #13). Given that I store my data on Unix/Linux machines, no matter what language I'm using, I change all 13,10 combinations into just a 10, then all 13's into a 10, which gives me my Unix/Linux like behavior. If you don't want to store any newlines then just change all 10's at that point into nothings (or a space). FYI, a newline (10) is often represented as \n and a carriage return (13) as \r. Hope that helps.

RE: [PHP-DB] using A NAME ref
I'm not sure what any of the posted sample code is really trying to get at
... but from what I gather you want:
a) Links at the top of the page, allowing somebody to jump to the
beginning of the section of people's who's last name begins with that
letter.
b) The names all come from the database, ordered by last name.
So, you end up with something like this:
?php
// Warning: I haven't tested, debugged, or even ran this
// through a syntax checker. It's completely off the cuff.
for($c = 'A'; $c = 'Z'; $c++) {
// This works in C... I assume PHP acts similar.
echo a href=\$PHP_SELF#$c\$c/a\n;
}
$recordset = ... however you query your particular DB.
$curr_letter = '';
$row = array_shift($recordset);
while ($row != NULL) {
// Making assumptions on DB fields here.
$lname = $row-last_name;
if (substr($lname, 0, 1) != $curr_letter) {
$curr_letter = substr($lname, 0, 1);
echo a name=\$curr_letter\\n;
}
// Print the user info now
$row = array_shift($recordset);
}
?
If you want to get fancy you could query the recordset first, then iterate
through the alphabet and for each letter scan ahead in the recordset
looking for somebody w/ a last name beginning with that letter. If none
found, print out a grey non-linked letter, and continue to the next one.
It'd be slower... but act a lot nicer.
If you're sure you'll have a last name for every letter in the alphabet...
just use something like I posted.
Hope that helps,

Re: [PHP-DB] how should i test my php program performance?
There are a few different things you can test here... I. Server Performance (overall) I don't have the name of any specific tool off hand, but basically you would request a slew of .php pages off of the server via HTTP and record how many pages/second actually are served up. This is really the only thing that matters in the Real World. II. Script Performance The replies to this thread have already mentioned functions which will help you calculate total time spent in a script. Good things to know, definately, but not the absolute answer. Quite often it's beneficial to place various outputs along your program (or script in this case) to figure out where any bottle knecks my lie. Personally, I place them just before and after a DB call to differentiate slow-downs between my actual code vs. my SQL code. This way you get to target specifically which pieces need optimization, if any. If II is plenty fast for you, but I isn't... start looking at processes running on the system which you don't need. If beyond that you want to squeak more out of the system, start optimizating your web-server config. Before anything though, a quick Big O analysis of your script could help point to performance problems before you can even see them in a benchmark.

Re: [PHP-DB] Please help!
I realize this is trivial... but if you're using things like the code
below alot it can clean things up a bit by using:
if (($counter % 2) == 0 ($counter != 0))
echo BR;
$counter++;
echo img src=whatever...\n;
Just reads easier... less branching, less code. In an ideal world it'd
optimize into machine code better than the below snippet too -- but that's
get anal retentive about the situtation :)

RE: [PHP-DB] Photo Album Schema
Going to disagree there... I'd use a seperate dir for each user, identified by their id. You can keep the original filename then for each uploaded picture. If two users have a family.jpg then you won't end up with any collisions. Something like: photos/1/family.jpg photos/2/family.jpg Manipulating directories which have a huge number of files can be cumbersome at times... at least it has been in my experience with some Linux machines. I once threw 16,000+ .gif files into a single dir and the standard GNU tools have trouble manipulating things like that. For instance, an 'rm *' won't work.. you need to script it in some way file by file. Just my two cents.

On Sun, 19 Aug 2001, Fotwun wrote: My questions are how do you securly, reliably, and seemlessly integrate sessions within that type of gateway. Because once the form data is posted to the credit card gateway, it redirects (posts response data) back to the script of your choice. However, in my experience, the sessions are not restored/recognized until the browser is refreshed on the client side (through the use of JavaScript) to get the server to recognize the request as coming from your user, rather than the as a post from the gateway. I don't want to have to deal with getting sloppy and adding additional refreshes/java script if thats the only way to do it. If I were to merely have the code generate a form based on hidden tags and have javascript auto-form submit, then I would open to security problems, because I could no longer restrict the script the gateway respondes to by an HTTP_REFFER. Whoa there buddy. HTTP_REFERER is supplied by the client's browser... and therefore should be untrusted. If you think it's secure because of what HTTP_REFERER says, you're mistaken.

Any ideas...? Maybe there's a quick solution out there I am just overlooking. The solution would be easy if I wasn't inserting all of my data at the end of the process based on the session data. But this is how the code is has to work, so what do you all think, how should I deal with this?

Don't put single ticks around a field which holds numerical data... unless
you defined your primary ID as a text field (hope not) that's probably why
the query is bombing out.

[PHP-DB] PostgreSQL connections within classes collisions.
I recently did a re-install of PostgreSQL and php4 on Debian, which has
broken some development code here. None of the actual code has changed in
days, which I can verify against the CVS tree, so I know it's one of two
things:
a) botched server config
b) the code wasn't as robust as it should have been in the first place.
What I have is a class (db_postgres) which we use for all DB access within
the project. The functions relative to what are breaking are as follows:
class db_postgres {
var $db_name = ourdb;
var $db_user = ouruserB;
var $db_conn;
// CORE FUNCTIONS
function get_connection() {
$this-db_conn = pg_connect(dbname=$this-db_name .
user=$this-db_user);
if ($this-db_conn == FALSE) {
echo Internal warning: Db connection not established.\n;
}
}
function execute_sql($sql) {
$result = pg_exec($this-db_conn, $sql);
if ($result == NULL) {
echo Error executing following SQL:hrpre$sql/pre\n;
}
return $result;
}
function get_rs($sql) {
// Returns an array of hashes
$this-get_connection();
$result = $this-execute_sql($sql);
if ($result == NULL)
return array();
$num = pg_numrows($result);
$result_set = array();
for($i = 0; $i $num; $i++)
array_push($result_set, pg_fetch_object($result, $row++));
return $result_set;
}
[snip]
}
The following main php page (ommiting includes) works:
$db = new db_postgres;
$result = $db-get_rs(select * from vendor);
$result = $db-get_rs(select * from vendor);
However,
$db = new db_postgres;
$result = $db-get_rs(select * from vendor);
$db = new db_postgres;
$result = $db-get_rs(select * from vendor);
Will break on the second calls ot get_rs(). Yes, I -could- be passing
around the db handles, or passing around already instantiated class
objects, but this gets a bit messy. Plus, everything was working dandy
with making two $db objects within a single page... which is why this
bothers me.
The actual PHP error upon the second call is:
Warning: 1 is not a valid PostgreSQL link resource in ... [snip]
Suggestions?

I can't think of a simple way to do it off of an include, but off the top of

Few things I think I should point out here. The first being that
str_replace() will replace -every- percent sign in the line, not just the
one that occurs as the first character.
If you know for sure that the the first character is always a % and you
don't want to print it just use:
print substr($line, 1);
as the body of your for loop.
Secondly, you're callilng count() for every iteration of your for loop.
Might as well call it once, store the variable and save the computation
time of repeatdly calling it.
Thirdly, and this one is perhaps a bit anal retentive, PHP treats arrays
as dynamically growing linked lists. So, when you call an array by it's
subscript the php engine starts at the head and walks X steps through the
list to get what you wanted. If you don't plan on re-using the array,
It'd be better to do something like array_shift() to get values from it.
Perhaps something like this would work better:
$file = file(data.txt);
for($x=0; $xcount($file); $x++){
$temp = str_replace(%, , $file[$x]);
print $temp\n;
}
unset($file, $temp);
?
$file = file(data.txt);
$line = array_shift($file);
while ($line != NULL) {
print substr($line, 1);
$line = array_shift($file);
}
unset($file, $line);
Note: I've never done file I/O w/ PHP... I'm just assuming that the
original post was correct there.

Re: [PHP-DB] Re: reload page
Actually... it's not a bad idea to refresh a page once it's been submitted, even if that frame could be displaying the results with only one hit. We do it around here on quite a few things simply because it prevents accidents from happening on the user's end. If you redirect back to $PHP_SELF or $SCRIPT_NAME you clear out any GET/POST variables. If the user hit's refresh (for whatever reason) you end up submitting a request that's already been executed once.

Well you asked if there was a way to refresh your target frame once a submission was made from an origin frame. This method would do that. Then again, why does the second frame not already display the results of the submission?? As it get's called from the first (origin) frame. Maybe you should re-state your problem and indicate use of DB's in there too, as I may easily have got the wrong end of someone else's stick. Cheers.

I think it'd help if you pasted the HTML code for your form. Plus, which browser/OS you're using to test this out would help too.
