From the above, you'd get an order number similar to 20080913-1048. This means that it's not only unique, regardless of how many orders come through in the same second, but ordering by time and date is easier, and on paper, you can easily tell when an order was placed. a handy trick, I would suggest this belong in the display layer of the app not in the DB. I was originally taught DB stuff from someone who was hot in FoxPro in the 80's ... back then it was normal to encode all sorts of info into unique identifiers (much like the way you describe) for the simple reasons of lack of disk space, cpu power and screen space ... these days best practice is generally accepted to be that a unique identifier is purely that and no more ... adding 'cruft' to a UID pollutes it and I would hazard to call it data-bastardization[tm] ... the date can (and should) be stored as a seperate field, output from the DB can always be displayed as you described. I think I see what your problem is. Basically, you've set the tables up in the wrong way. Every order system I've used has one table for the orders, one for the customers, and one for the items attached to an order. This makes management a lot easier, and you get to use those auto_increment values you so need. From what you've been saying I'm guessing this is a custom built system, so hopefully it shouldn't be too hard to change now if it's not finished. If it's something you have purchased to use... well, I'd look for something else... Ash www.ashleysheridan.co.uk

RE: [PHP] 2 Questions.
That's cool thanks. I agree with you too it's mankind's folly. But regarding
the db question, I got the idea from CakePHP which solves the problem of
having to prefix your columns ie user_name etc etc. I think you can use
another built in php database function num_fields() and hook into the meta
data and then you would have to manually build the information into array.
I'm not sure but I'm going to hack around with it a little and see what
happens.
Thanks Thomas

[PHP] 2 Questions.
Can anybody give me any good reasons not to use a time stamp as an order number in my shopping cart. It seems to me that the number is guaranteed to be random and it saves having to make an extra time column to keep track of the order. The only small concern I have is the chance that somebody orders at the exact same time as somebody else but the chance of that has got to be incredibly small but possible. My second question is I've designed a very simple Postgres database wrapper. The methods are exactly what you would assume to see in any db wrapper a pg_query, pg_fetch_array. My question is in the db wrapper, is there an easy way to always include the table name as an index in all my pg_fetch_array returned results?

Cheers Thomas Shaw [EMAIL PROTECTED] Well, I think you answered the first part of your question yourself there! Although remotely small, it is entirely possible for two people to do something at the same time on your site. Why don't you use an auto_increment column in your table instead? There are plenty of functions in PHP to retrieve the auto_insert value (although generally different for each type of database you connect to, I only know how to do it in MySQL and MSSQL) This way, you let the database deal with the unique ID's as it's something the databases are very suited to, and you can then use the auto_insert ID in place of the value you would normally generate in PHP.

An order number should be a unique auto increment id (i.e., sequential) in your table. It should be representative of the customer's order -- it should contain the customer id; shipping/billing address; what the customer ordered (all items ordered); the time-date of the transaction; authorization code provided by the clearing house; and payment amount -- and basically nothing else (i.e., No credit card information). While you might think an order number should be something else, keep in mind that an order is simply an order. It is a point in time where a customer has agreed to purchase something and you have accepted and have cleared that purchase for that payment through some sort of purchasing scheme. It makes no difference if your dB is normalized, or relational, or some stock-boy working in a warehouse, or a phone order operator pressing an Done button. It is simply an order number. While you might think a microtime stamp would work, a unique auto increment id will work better. /opinion based upon experience My second question is I've designed a very simple Postgres database wrapper.

I'm not sure if I understand your question, but I'll try to answer what I think you are asking. Regardless of the dB, I find it best to have a configuration file that contains and defines all the variables re the dB (i.e., db_name, db_user, db_password, db_tablewhatever, and so on). That way, all you have to do is to include that file in your scripts. If you want to change something, you can change it in just one file.

Nice to see you back my friend -- I was worried. An auto-increment field in a table is unique. While it doesn't include any time/date information, it is automatically assigned when the transaction is confirmed (i.e., INSERT). I've used both, but usually when I need a time/date stamp, I add that somewhere else in the table. However, these are just differences in style and not that one is better than the other.

to prefixing my column names i.e. users_name instead of just name or
forum_posts instead of just posts to make sure there's no collision.
have your simple wrapper do something like:
$sql = SELECT foo AS {$tablename}_foo FROM {$tablename} WHERE 1;
with regard to generating the query. if your wrapper doesn't generate the
SQL then you'll have to parse the given SQL and rewrite it ... good luck
with that.

[PHP] 2 Questions: Static variables and the nature of the online manual
Hello,
I got this e-mail address from the Add note¹ page within the php.net
website. I was going to post something that was a question and I realised I
was in the wrong place :)
I have 2 basic questions and I¹m sorry if they may seem too basic. I¹m a bit
new to php.
The first question has to do with the static variables. I understand how
this works from the examples, but there is something that I cannot seem to
find clearly stated anywhere on that page.
The example:
?php
function Test()
{
static $a = 0;
echo $a;
$a++;
}
?
Of course works (I¹ve tested it on my server), but it is still obscure to
me, according to general programming principles, since I¹m still assigning
zero (0) to $a on each call to the Test function. How does this exactly work
when the static word is found? Is there and index that keeps track of each
call to the function ignoring any assignment in subsequent calls to the
function? Why doens¹t this work when you assign an expression result to the
variable?
The second question has to do with the online manual. I¹ve found several
things on that manual specified in comments and not in the actual manual
part of it. What is the nature of the manual? Contributions from voluteers?
Is there any official manual I can buy that documents everything about the
language from the source? Or any official company that maintains the
language and that possibly offers support as well?
Many thanks in advance for your time.

php.net/ is the official manual. recommended to read it in english so your
looking at the latest version (not always the case in other languages).
user notes/comments are exactly that - notes, tips, gotcha's, examples related
to whatever is documented on a given manual page. occasionally some of the best
user notes are merged into the official documentation.

Re: [PHP] 2 Questions: Static variables and the nature of the online manual
Hi there,
Many thanks for your answer. I've also gone through your example and it took
me 10 minutes to understand how the operator precedence was working there.
Was expecting 1 on the first call :)
But this is not the point. You've nailed my question very preciseley in your
first answer: 'the preceding line is only run on the first call to the
function'.
My only question is (at it is related to the nature of the online manual):
how do you know it and I don't? This thing is the only logical explanation
to the fact the $a doesn't get initialized again to 0 in any subsequent call
to the function, but it's not written anywhere in the manual page. And it
seems the most important statement in my opinion, that justifies what I see
as an exception to a normal flow.
Hope all this makes sense.
Thanks,
S

We (the PHP community) maintain the manual through registered CVS
accounts. As Jochem said, php.net is the official manual - there is
no official manual to buy, and no way for a company to document
everything about the language. This is because, believe it or not,
the language changes multiple times per day, with added functionality
all the time. The best a company could do is document everything on a
specific version but by the time that task is complete, the
version documented would be obsolete.
The comments are just posts by whomever feels like typing and
submitting. It's generally a tips and tricks sort of thing, and is
an excellent source, but an unofficial source.

Check the section Using static variables in the Variable Scope entry here:
http://us.php.net/manual/en/language.variables.scope.php
I mean, I understand the manual is maintained by the community, but I
suppose the language is developed by a small core of programmers that
participate to the general discussion to some extent...
Actually, a good portion of us who maintain the manual maintain
the code, as well. Everything about the language, from the core
engine to web scripting support, is handled entirely by the community.
That's the beauty of open source.
I'm just trying to figure out the shape of the landscape. I tend to start
from the bigger picture before getting into details. :)
And welcome to the community, Svevo!

It's not an assignment, it's an initialization, and, yes, the compiler
does keep track and doesn't do that after the first time.
*THIS* would be what you describe:
function Test(){
static $a;
$a = 0;
echo $a;
$a++;
}
The second question has to do with the online manual. I¹ve found
several
things on that manual specified in comments and not in the actual
manual
part of it. What is the nature of the manual? Contributions from
voluteers?
The manual is contributions from volunteers who have been blessed by
the other volunteers (viz) to edit the manual.
The Notes is from anybody on the planet with a web browser that can
beat the CAPTCHA.
Is there any official manual I can buy that documents everything about
the
language from the source? Or any official company that maintains the
language and that possibly offers support as well?
There is nothing you can buy that's more official (nor more complete)
than the on-line manual.
You can buy support from Zend, which is a separate company run by two
guys who happen to be core developers; You can probably buy support
elsewhere as well.
PS
If you can find a language with a better manual, I'd like to see it...

Re: RES: [PHP] 2 Questions: Static variables and the nature of the online manual
Cheers Thiago, In fact this was going to be my next question. I think I will report a documentation bug, just because, after all the discussion we had today, I realize that this is quite a common behaviour in other languages, but for somebody new to languages, being them programming or scripting ones, the fact that the $a=0 line doesn't get executed on subsequent calls isn't so obvious. In other words, from the standpoint of someone that is relatively new to the details (at least), the flow is: 'ok, I do appreciate that the engine keeps memory of the value of that variable declared as static after the function ends, but assigning a value to it at the very beginning of the function seems like the next time the function is going to be called, it will assaign that value again and again...and again'. And I guess the manual wants to be as clear as possible, considering that the examples are often 'foo 'and '$a' related :P In other words I think that it is indeed targeted to beginners as wel, isn't it? Thanks for all the valuable info btw. :) In 4/3/08 16:59, Thiago Pojda, [EMAIL PROTECTED] ha scritto -Mensagem original- De: Svevo Romano [mailto:[EMAIL PROTECTED] Hi there, Many thanks for your answer.

I am not used to use ' - ' to call a method if you know what I mean, but the rest is quite familiar, phew! :) Aside from that, this was just one of the things I could not really understand properly: I could understand the effects, not the reasons behind the effects, if it makes any sense. I think the manula is lacking a couple of lines. One funny thing: in the Welling Thomson - PHP and MySQL Web Development book, at some point this thing is mentioned. They promised they would explain the concept in full detail in chapter 5 and, in chap 5, they kinda forgot to do it.. hehe All the best.

Re: [PHP] 2 questions: Search in array and detect JS
for js detection, you can use that in a previous page :
script type=text/javascript
document.write('a href=ajax-page.htmlpage/a');
/script
noscripta href=simple-page.htmlpage/a/noscript
it is simple, and work fine.

methods discussed focuses on the fact that you are sending this person from
a previous page,eg:index.php to- contact_us.phpbut what if you are using
AJAX on the first page (eg: index.php)then isnt the location.href =
'/url/for/ajax/index2/page.php'; the best solution?Cheers!Ryan

However there's even more at stake--this solution would require you to manage *two* versions of your page. Come on, we can do better than that... What you should do is create your normal page as is, and then write your javascript to attach itself to whatever things you want to AJAXify on that page. Research unobtrusive javascript, it should get you in the right direction. The idea is, you build your page to function normally without any javascript. Then you attempt to hook up the javascript via your page's onload event (there are other methods too I believe, Google it). If javascript is enabled, then the javascript will be hooked in; if not, then no AJAX will be loaded, but your page will still function as needed.

(1) I am using a class to send email, 3 different kinds (text, html, text+html attachement) no problem there, but I am giving the client the option to mail all his members/clients at the same time...I have set the timeout to +30 everytime it loops so each email has enough time to go through even if its a couple of thousand, heres my problem: I want to display a message after each mail has gone through eg: after the first mail it says: Mail #1: Sent the after the second mail Mail #2: Sent etc etc something like a progress bar...but for now, it waits then loads the whole page at a go instead of one by one. I have looked at the manual and the closest I can come up with is to use sleep() but even then am not getting the display like that and its of course slowing down the sending of mail. Next I looked at buffering...which is not really for my needs either... Any ideas? (2) We are developing a developer site and its going to be php powered and very php related, we want to have that php function search facility that php.net has eg: you type http://php.net/mail and it shows you the mail functions page... I searched the php.net site but I couldnt find any reference to how they are doing that...

I have two questions for you today: 1. Weired login problem I am developinig a site for a conference where i have a login page for members. This page is called index.php and includes different types of modules, according to the type of user logged on. The problem is now following: i have a login function hidden in a class, this function registers a bunch of variables. After the user has submited the details, index.php (which calls the session_start()) calls the login function. Then i check whether a session variable is present ($_SESSION['name']). If yes, we include the members area, otherwise we include the login table again. Now: on my test server (XP/Apache/php4.3.2) all is well. However, on the real server (Linux/Apache/php4.0.x) it just includes the login table anyway, even if the login was successful. I then have to click on the menu link again to include the member script. Why is that? Check your register_globals setting in both ur test server and real server and let me know. 2.

[PHP] 2 questions
Hi guys. I have two questions for you today: 1. Weired login problem I am developinig a site for a conference where i have a login page for members. This page is called index.php and includes different types of modules, according to the type of user logged on. The problem is now following: i have a login function hidden in a class, this function registers a bunch of variables. After the user has submited the details, index.php (which calls the session_start()) calls the login function. Then i check whether a session variable is present ($_SESSION['name']). If yes, we include the members area, otherwise we include the login table again. Now: on my test server (XP/Apache/php4.3.2) all is well. However, on the real server (Linux/Apache/php4.0.x) it just includes the login table anyway, even if the login was successful. I then have to click on the menu link again to include the member script. Why is that? 2. Save a large amount of text to a file On the same page i have some type of cms going. The admin users can change txt files which relate to text on some of the general pages. I have now found that it is only transmits a certain amount of text via GET to the function that writs to the files. Is there a restriction on passing text via url?

RE: [PHP] 2 questions
The register globals is on with the live server, and off at home (my version is 4.3.2, the other is 4.1.2). does that matter? Thanks for the other tip, shall try that ...

[PHP] 2 Questions Re: Anonymous Functions
I'm extracting a list of items from an XML document using PHP. The desired
items are the attributes of different occurances of a specific element
within the document; the code will not need a callback for character data or
for closing tags.
$list = new Array();
function start_tag($p_id, $element, $attribs)
{
global $list;
if ($element = 'building')
$list[] = $attribs['address'];
return true;
}
//.. snip .. snip ..
xml_set_element_handler($parser, 'start_tag', create_function ('',''));
//.. snip .. snip ..
Two questions:
1. create_function ('',''); works just fine, but I was wondering if there
was a proper way to declare a void anonymous function?
2. If I were to place the parser related code within it's own function to
increase readability of the script, how would start_tag be rewritten as an
inline anonymous function? I've tried several ideas but I'm not sure how to
handle $location and it's change in scope.
Thanks in advance,
-Tim

[PHP] mail via php. 2 questions...
The first problem I cannot solve on my own: I get the mail content from a cookie. Quite a big cookie since it is a collection of 30 - 40 form values from another page. When recieving the mail, the content come in ONE long string, and in some places with a \BR\. Of course, i dont want this to be printed (but I want the function, a line break). So, how can I get a line break in my javascript cookie (yeah, I have already tried \n). The second problem: I want the mail to be sent automatically when the visitor have filled in all the forms in the document and goes to the next document. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] 2 questions about performance...
Is it in-efficient to use shuffle()? I have a simple 6 element array with 6 strings (URLs to images) and I'm using shuffle() to display all of them in random order upon each page load. The images take a long time (of course is relative, it's mere seconds) but when I remove the call to shuffle, they appear much much faster... Also, is there an efficient number or limit of queries one should call in a singular PHP page? On average, I'll make 7-10 seperate queries to display a page (a graphics related portal and content management system)... I have a singular database connection (with mysql_pconnect()) and use that same connection throughout the script. Sometimes it appears to load quickly, than other times it doesn't, and I'm afraid that as more and more content get put into the databases, the slower it will perform. user authentication navigation (link definitions) form dropdowns (dynamic selects) banner rotation (2 sets, big and small) activity tracker headline or story retrieval comments Joseph E.

Re: [PHP] 2 questions about performance...
simplest answer is find out yourself. every machine will depending on config and
hardware will be difffernet.
?php
function mtime()
{
$mtime = microtime();
$mtime = str_replace('.', '', $mtime);
$mtime = explode(' ', $mtime);
$mtime = $mtime[1] . $mtime[0];
return($mtime);
}
class debug
{
function debug()
{
$this-start = mtime();
}
function reset()
{
$all_vars = get_object_vars($this);
foreach($all_vars as $pos = $val)
if ($pos != 'error')
unset($this-$pos);
}
function time($text = '')
{
$this-break = mtime();
$time = ($this-break - $this-start) / 10;
echo number_format($time, 4) .' '. $text ."br\n";
$this-start = $this-break;
}
}
$debug = new debug;
//---
$debug-time('start');
// code snippit
$debug-time('end');
?
works great or me. you can find out exactly where your code is slowing you down, only
thing is now to find out how to improve that :)

[PHP] 2 questions
Hi I have a couple of questions. One about hosting and the other about IP addresses. The first on the IP's. I have been speaking to a company that I am looking at getting a dedicated server from. They ONLY do one IP address per server and use name-based hosting. I have asked for dedicated IP's, but their answer has been that all hosting companies are going to have to go to name-based hosting now. What is everyone's feeling on this? Years ago, the company I was with used name-based and I remember that the search engines did not like this On to hosting, the above server is a Cobalt Raq 4i. Does anyone else on the list use one of these and what do you think?

Re: [PHP] 2 questions
I use a RaQ3 and have no problems running PHP and MySQL. I started out using one IP but the biggest problem I found was that in order to view the site or make changes to it, the domain name must resolve to the server before it would work. I decided it would be best for me to assign each site an IP and go with it. I am not sure who you are talking to about a dedicated RaQ but look into http://www.4webspace.com. I have a RaQ3 with 100 gig transfer and 30 IP's for $110 a month. They do have RaQ4's for a little more money.
