The code is:

The command 'global $SESSION;' is the first line of the script.
$SESSION is the session variable created with

session_register(SESSION);
don't use session_register(), use the $_SESSION superglobal instead
(notice the underscore) ... you can read in the manual about this.
additionally you need to load in the class before you start the
session.
so the code would look something like:
require 'Cart.class.php';
session_start();
if (!isset($_SESSION['cart']))
$_SESSION['cart'] = new Cart;
function foo()
{
// no need to use global on $_SESSION
$_SESSION[cart]-web_order_change( true );

if ( !isset($SESSION[cart]) ) {
$SESSION[cart] = new Cart;

I am guessing this is a change in OO handling, any idea what is going

the crux of the problem lies in the use of outdated session semantics, I'm

[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.

$static $a = 0;
Here you're essentially saying new static variable $a with a default
value of 0 - the fact defined staticly means that next time you call
the funtion, $a has a value so therefore doesn't need the default.

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.

I was just referring to an old benchmark [1] I had seen a few years ago. Of course the biggest win will come from an opcode cache if that is a possibility. Just for the record I do use a db wrapper myself but I have weighed the pros and cons of the situation and determined that it works for me. I have many low traffic sites so it makes sense to have a wrapper that delays connections until they're used and such other little tweaks. I listen to peoples recoded talks from conferences and I've heard on many occasions that on single apps they take out the db abstraction. I wish I could cite references but it is out there if you want to dig enough.

He might not have loaded the class definition also. That'd lead to
the nasty __PHP_Incomplete_Class. Or maybe it is something to do with
class names in php4 weren't case sensitive whereas in php5 they are.
I've used the unserialize_callback_func feature before to auto load
classes.

Re: [PHP] maintaining [user] state without a session ...
Hi,
It depends what do you need to track,
if you need to track small amount of variables you can do it by cookie
I often use it eg here is the state for one user
$state = array{
'logedin'=true,
'n'='Peter',
'id'='5',
//anything else you need
}
//at end of you script before outputing any content
//set cookie only for browser session and set path to '/' so it is
available through whole site
setcookie('user_data',serialize($state),null,'/');
At the begining of a script
$state = isset($_GET['user_data']) ? $_GET['user_data'] : null;
if( ! $state ) {
//user doesnt support cookies or this is a search engine set
default $params
$state = array{
'logedin'=false,
'n'=null,
'id'=null,
//anything else you need
}
}
Also you can use some way to detect if the user is not Search engine
to display message like
To properly use this site you need to enable cookies in your browser
bla bla
This can be done via JS alert message which will not be triggered by
SE but only by real user

I'm not sure if this is what you are asking for, but occasionally I
have an include file that just brings functions and sometimes I want
to know if that file has any errors in it.
As such, I simply add echo('a'); at the beginning of the file. If I
run the script that includes that include and see an 'a' printed at
the top of the page, then I know that the include has no syntax
errors. Then it's simple to comment out that line.

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

Hello,
I got this e-mail address from the ŒAdd 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;
the preceding line is only run on the first call to the function.
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?
do something like
function Test()
{
static $a;
if (!isset($a))
$a = 0;
if ($a % 2)
$a = $a * 2;
echo $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?
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?
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.
Many thanks in advance for your time.

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:

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. :)

As far as I know, the only way to do that is via the CLI (or

But you should use CSS:
echo 'trtd style=color: red' ...
But if you're going to use CSS.. it would be better for managing it
to do it as a style sheet:
style
.red {

/style
echo 'trtd class=red';
Just my opinion :)
And a good one -- other than not putting them in the html, but rather
in a style sheet.
I see no problem whatsoever in using css to do that and --
.bold
{
font-weight: bold;
}
.floatRight
{
float: right;
}
-- other such obvious style elements. At least those are pretty self
explanatory.
If you want to get specific, then start naming your classes and id's
to specific things, like:
#mainTitle
{
color: red;
font-weight: bold;
float: right;
}
Do your best to keep all languages separate.

Andrew makes a good point, Jason. Despite the fact that it's just
a reference, it's easier to make a general reference to highlight
that can later be changed to weird colors like shale, aquamarine,
coffee, and taupe, than to have a style called red and have a future
designer look at the source and say, damn, that Jason Pruim guy
doesn't know his .red from a #804000 in the ground.
Yes, but there are two points here.
One is if you want to be specific about a design element, then call
it whatever you please. But, if on the other hand, you want a general
old-world font-color, or font-bold, or font-whatever, then you can
use css to do that for you very easily.
I am not saying use class=red that might later be changed to green
-- that would be very short sighted. But let's say you have a client
that wants BUY to be red, I don't see any problems with using
class=red in your html tag.
Also, later if the client says That red is bright enough you can
always change it to another shade without violating the red thing..
If the client say I want that to be green, you can always refer to
the design specs that said otherwise; do a global search and replace;
and bill for your time.
All I'm saying here is to consider easy-to-under semantics in writing
css rules.

I listen to peoples recoded talks from conferences and I've heard on many occasions that on single apps they take out the db abstraction. I wish I could cite references but it is out there if you want to dig enough. duh. ofcourse they do that. remove a layer of abstraction and win some speed. it a game of dimishing returns, take the big target first - that's usually the SQL queries, DB tuning. next step might be op-code caching, then data/output caching, and if that's not enough (or you have enough iron in play to make the numbers add up) you start to remove maintainability and/or abstraction from your code to win a few cpu cycles. php is web-glue, or for the purposes of my metaphor web-butter ... generally the sandwich is mostly filled with something other than butter.

Never miss a thing. Make Yahoo your homepage.
Keeping with your example, this works and doesn't allow an empty string
(to allow empty, replace the + with *):
eregi('^[a-z]+$', $fname)
-or-
ereg('^[A-Za-z]+$', $fname)
But ctype_alpha() is a better multi-locale solution.

What you tried only requires ONE a-z character somewhere in the input.
Try this:
preg_match('^[a-z]+$', $fname);
This will:
^ anchor the string at the beginning
[a-z]+ a to z, with at least one letter
$ anchor the string at the end
Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.
Oh, and the digit 3, for bo3b who was a programmer on the first
Apple Macintosh. His parents were hippies, and that really is his
name...
You may want to obtain a LARGE list of first names and run them
through your validator as a test.

Hi,
It depends what do you need to track,
if you need to track small amount of variables you can do it by cookie
I often use it eg here is the state for one user
$state = array{
'logedin'=true,
'n'='Peter',
'id'='5',
//anything else you need
}
//at end of you script before outputing any content
//set cookie only for browser session and set path to '/' so it is
available through whole site
setcookie('user_data',serialize($state),null,'/');
Woof.
So anybody with half a clue could look in their cookies and change,
say, 'id' to '1' and masquerade as anybody they want in your system.
And with an 'id' of '1', they might even getting CMS 'admin' access or
something.
Probably not a Good Idea...
You could, perhaps, use a 2-way encryption algorithm and try to keep
your key as securely as possible, and do this much more safely.
Also you can use some way to detect if the user is not Search engine
to display message like
To properly use this site you need to enable cookies in your browser
bla bla
This can be done via JS alert message which will not be triggered by
SE but only by real user
Use robots.txt to keep out real search engines.
Anybody who REALLY wants to can run your JS with Webmonkey, the JS
engine of Firefox, released as a stand-alone command line tool.
(E.g., JS email obfuscation is useless against somebody with
webmonkey. Try it and see!)

Re: [PHP] 2 Questions: Static variables and the nature of the online manual
On Tue, March 4, 2008 6:16 am, Svevo Romano wrote:
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?
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...
:-)

$SESSION is the session variable created with

I am guessing this is a change in OO handling, any idea what is

I don't think it's a change in OO handling, maybe it's a change in the
error_reporting level for the new version and you hadn't noticed the
problem before.
The problem is that $SESSION['cart'] isn't an object - you'll have to
work out why.
It could be that $SESSION['cart'] is getting overridden at some point
with another type of variable.

RE: [PHP] GPS Locator
While this has deteriorated way off topic from PHP, I will just mention that I've purchased several GPS from these cats and had great luck: http://www.buygpsnow.com You *might* be able to write a custom PHP extension that you compile into PHP that can access the USB/Serial port as well. (and if you did got this route, which would be the most beneficial to the PHP community, I hope you would FOSS the extension so other's could use it perhaps) http://devzone.zend.com/node/view/id/1021 Secondly, maybe you could have a little daemon written that simply spits out the coordinates (lat/long/altitude/etc.) to a socket or something, and then via PHP's socket functions you could continually read that in. Alternatively, perhaps JAVA will also let you access hardware layers if you're on a non Microsoft platform (which is generally the case for PHP users). Lastly, you could certainly do some low level hardware I/O with Ruby and then perhaps use Rails for the web portion.

$output
?
***
The $drawrect, $button2, and $get are NOT php functions, but to be
printed
as actual text (which is why I have escaped them with the backslash).
Anyways, I thought it would be easiest to separate each R-G-B value
into its
own variable ($n1, $n2, and $n3). That way I could just use some code
(regex?) to cycle through the numbers 0 to 255.
The HARD part (that I can't seem to even think of a way to make it
possible)
is to change JUST the G and B values while keeping the R value at 255.
Then
when the G and B values both hit 0, the R value is set to 254 and
repeated
until it also hits 0 with the other two. I think (?) that will do
every
possible color? I also need to print each string with the individual
color
output, and I don't know how to do that either.
In short, I would like something that looks just like the windows
color
picker, and when each pixel of it is clicked, it will show me the
R-G-B
value in the format I would like.
If anyone understands what I am after,and could help, that would be
awesome!

Re: [PHP] PHP performance
#1 Get the code, install it on a box in the closet, run valgrind --callgrind This will give you a stack trace of what gets called the MOST in your application. Look for tall trees in the call graph, and fix those first. #2 You can use 'ab' (apache benchmark) or similar to test it externally. #3 You can also script things with Selenium IDE and then use Selenium remote control to run them repeatedly, for the end-user experience.

What you tried only requires ONE a-z character

Try this:
preg_match('^[a-z]+$', $fname);
This will:

[a-z]+ a to z, with at least one letter
$ anchor the string at the end
Note, however, that some people have other

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'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.

Re: [PHP] 2 Questions: Static variables and the nature of the online manual
Yes Richard, In fact I know ActionScript and JavaScript and I'm trying to nail the peculiarities of php. I totally agree. 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] Importing and exporting from MySQL, escape slash problem
Richard, Jed, Thank you for replying. Richard said: It's possible that there is an .htaccess file in phpMyAdmin that has Magic Quotes on that is messing you up... The .htaccess file for phpMyAdmin says php_flag magic_quotes_gpc Off, so I guess that means I'm okay there. Other than that, it's specific to phpMyAdmin, so maybe ask those guys what they did... I joined their list through Sourceforge, but I haven't seen any mail from it, and any mail I send gets bounced back to me. I'm not sure what the issue is. Jed said: If you're having trouble importing a mysql dump using phpMyAdmin, it might be simpler not to use it, and use mysqldump instead. I suppose I'll have to if I can't get phpMyAdmin to behave.

Re: [PHP] validating mysql bound date
Thanks,
I ended up doing:
$incomingQuestDatePieces = explode(-, $incomingQuestDate );
if(checkdate($incomingQuestDatePieces[1],$incomingQuestDatePieces[2],
$incomingQuestDatePieces[0]))
{
return true;
}
else
{
return false;
}
I was just wondering since a lot of people have to verify correct format
of the date when working with mysql that there might be some built in
that is faster etc.
Thanks though...
