Hi,
I was not having PHP on the machine I am reading this email for the moment. But I tried to use it together with egrep, but it didn't work. Maybe egrep is using different syntax for these lookaheads, but with other tests it has been working same as for preg_match in PHP. As you see the first simple example works, but fails when I insert the lookahead. 

[EMAIL PROTECTED] ~]$ echo 0123 | egrep '^[0-9]{4}$'
0123
[EMAIL PROTECTED] ~]$ echo 0123 | egrep '^(?=.*2.*)[0-9]{4}$'
[EMAIL PROTECTED] ~]$

/Peter



Quoting Martin Alterisio <[EMAIL PROTECTED]>:


PS: I think you can remove the last .*, leaving the assertion like this:
(?=.*8), and it will still work fine and probably faster (which dosen't
matter under these conditions). But I haven't tried that one (and have
already erased the test file I did to check the regular expression).

2007/2/9, Martin Alterisio <[EMAIL PROTECTED]>:


If you want to do it in one regular expression, without listing each case,
you can use a lookahead assertion:

/^(?=.*8.*)[0-9]{4}$/

The assertion (?=.*8.*) checks that the following matches the expression
contained (.*8.*) which fails if there is not an 8.

2007/2/9, Peter Lauri <[EMAIL PROTECTED]>:


Best group member,



I want to match a four digit number. I allow user to enter with *
syntax. So
8* would match anything that starts with 8 and is 4 digit long so:



/^8[0-9]{3}$/



That was easy. Ok then my other case was: *8, so anything that ends with
8



/^[0-9]{3}8$/



Ok, now the tricky one comes: *8*, so match it incase 8 is anywhere in
the
number. Can be beginning, end or in the middle. The problem that I face
I
cannot find out a good way of doing this correctly. So I ended up with
an
expression like this:



/^(8[0-9]{3}|[0-9]8[0-9]{2}|[0-9]{2}8[0-9]|[0-9]{3}8)$/



This takes care of it and everything, BUT it is so ugly. What I actually

need to construct is: A regular expression that checks if 8 is a part of
the
number, and then that it is four digit long.



The pipe "|" is an OR operator, but are there not any "AND" operator in
Regular Expressions? I have been trying to figure this out for a while
now.
Of course I am using the above syntax right now, but would like to strip
it
down. Maybe not for the performance, but for the beauty of it :-)



If you have any comments and suggestions about this I would be happy.



Best regards,

Peter Lauri

I couldn't get egrep to work either but the following cmdline output
shows that the given regexp will do the job with preg_match:

tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "8123"),"\n"; '
1
tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "08123"),"\n"; '
0
tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "0812"),"\n"; '
1
tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "20812"),"\n"; '
0
tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "2081"),"\n"; '
1
tina:~# php -r ' echo preg_match("#^(?=\\d*8\\d*)[0-9]{4}\$#", "2008"),"\n"; '

Hello,

I have seen some implementations of Server in php implementing HTTP Digest
Authentication but I have not seen any guidelines on HTTP Client connecting
to a specific host, and using the "realm", the username and password to get
authenticated and thereby do something like download files etc.

Any help on there?

Thanks

Why do you need to rewrite URLs?

Hi,
I am a Mac person first and foremost, but the Windows people that I know tend to use Homesite: 

http://www.adobe.com/products/homesite/
From what I can tell, even though it is bundled with Dreamweaver 8, it still looks like it can be purchased and demoed separately.

I've been using SciTE for many years now.

http://www.scintilla.org/SciTE.html

It's small and lightweight, has code folding and bracket highlighting and a
lot of other nifty features.

I also have Zend Studio IDE Professional but it is slow and bloated compared
with SciTE.

gives in depth, detailed advice on how to design/setup redundant,
load-balanced, high-performance web-server systems/applications with particular
focus on PHP.

I just bought 'Building Scalable Websites' by Cal Henderson and that's looking
like it's a good place for me to start, maybe someone has another 
recommendation?

I understand that the headers_sent() function will tell me whether headers
have been sent or not.
What I do not understand is what triggers the headers to be sent to the
browser in the first place.
Does this happen as soon as the first output occurs?

It happens just "before" the  first output occurs to the browser.

Probably. Unless you have output buffering enabled, in which case
headers are sent when the PHP process completes.

or whenever the outer most output buffer is flushed [to the client]

Hopefully I will manage to explain my problem and you will have a solution 
for it :).
I have a checkout page, coded in PHP (by some other coder, not available 
anymore). On the page I have one table containing shopping cart items and 
one submission form, to collect all information from the customer. When the 
page is loaded, the table is filled with data from the temporary data table 
through SQL query (collected on the previous page, shopping cart page), 
except for the field about the amount of the sales tax, which is not yet 
known because I don't know anything about the customer. So I have a shopping 
cart table and a blank form below that, ready to be filled with customer's 
information.

Now, my question is: How can I calculate and fill the sales tax field in the 
shopping cart table, if the customer chooses his state from the drop down 
list in the form? I must say here that the sales tax is only applicable for 
residents of just one state, Vermont, because the company is based in 
Vermont. For instance, if the customer chooses Vermont as his state, how 
this can be translated into sales tax amount, added into the field in the 
shopping cart table and recalculated the total amount? Should the page be 
reloaded, with changed value of some variable for the sales tax? Should the 
JavaScript be used?
All information entered in the form should be kept after the selection of 
the state and calculation is made (I assume that the page should be 
reloaded/refreshed), so the user shouldn't have to re-enter them again.
After this recalculation, the customer hits the "Make Purchase" button and 
the form is submitted and the receipt for the purchase is sent.



I'm not very familiar with PHP or JavaScript, so any help is greatly 
appreciated.




Thanks,
Robert

Greetings,
This is about to your aproach to problem.

For my point of view there are too many solution.

1-) Is that customer may have to register himself? If so you may get from his 
state date from here (when customer register himself you require his state 
data). This solution can be done in PHP.

2-) If that justomer may not have to register. This is mainly Javascript 
solution. A liddle js library may solve this. Of course you can post his data 
to server and calculate tax then post back again.

3-) And or you may generate ajax solution for this. When user selects his 
state, script auto post and get calculated tax.

4-) and of course BEST WAY is find a professional php programmer. Then tell 
what do you want. 

Ps: Also you may guessing STATE via IP number checking. (and this was not 100% 
safe way)

we figured as much.

can you not redirect stderr/stdout from the cmdline that starts your script?
otherwise you would be stuck with not using those constants and defining 
variables

Actually, wouldn't you say it is left up to whoever is sending the cookie?
But more on that later.

Here is my point of view, if you are interested.  When the specification
for a language reads "encoding is recommended, but not required", then
it is leaving the decision to encode or not to encode up to the sender.
The sender is in the driver's seat and the receiver must follow suite.
(Side note: this is an inherently BAD specification since it requires
out-of-band agreement between the sender and receiver, and this is what
puts the developers of PHP in such a tough position.)  The receiver must
be able to handle either case.  But PHP does not permit this.  Instead,
PHP, in an attempt to avoid the chaos inherent a bad spec, has made the
decision for the sender.  The sender must encode, and has no choice.
I think this is at the root of my frustration.  I want control. :)
Also, keep in mind that in my case the sender is a third party over
whom I have no control.  Given a spec like this, I prefer cooperation
between sender and receiver rather than a decision by fiat made by the
programming language.

Now that I have seen the spec (thank you!), I can at least understand
why the PHP developers made the decision they did.  I still disagree
with it, but I was seeking only an understanding, and I have found that.
I hope you will agree I was not trolling here.

Oh.  One more thought.  If you wish to argue that PHP does provide
for both cases with $_COOKIE and $_SERVER['HTTP_COOKIE'], then I will
grudgingly agree with you.  See we can agree. :)  In that case, all I ask
is for a little documentation.  Is the distinction in these two variables
documented somewhere?  I have looked and looked and have come up empty.
I am asking this question with humility and sincerity.  I am asking it
because I honestly wish to learn.  I think you have misjudged my motives
and my character.

Thank you,
Fletcher

But isn't the sender and receiver usually one and the same. I mean your
PHP application is usually what set the cookie in the first place. Then
you receive it in the very same PHP application. I realize that the
cookie is technically sent by the browser, but the browser doesn't
process cookies other than to store them. It's akin to sending a message
into the future to yourself in some encoded format. You are both the
sender and receiver and so one would expect you can decipher your own
message.

Well PHP made the decision with the greatest flexibility. It chose to
encode the cookie in such a way as to allow developers to include
special characters in the cookie value.

You have control over the value you insert into the cookie. If you find
the encoding problematic, you have the control to encode it first in
base64 (as this message happens to be titled). So where exactly do you
see loss of control?

Ah, so you have a mixed language environment. Well you can use the
header() function to send the cookie header yourself. This allows you
control over the sending. You can also use  apache_request_headers() to
get full control over the incoming request headers.

Yep.

I'm not aware of a $_SERVER['HTTP_COOKIE'] field. Perhaps you meant
$GLOBALS['HTTP_COOKIE_VARS']? If so, it is identical to $_COOKIE with
$GLOBALS['HTTP_COOKIE_VARS'] being deprecated.

Hope that helps.

It is totally left up to the user with PHP as well, but you agree with that (grudgingly) later. There is no way that you can argue the fact that there are two mechanisms. One leaves total control up to the user, the other is totally automatic. Personally, I think that's having your cake, and eating it too.
I won't argue that this behavior should probably be documented with $_COOKIE, but it is documented with it's counterpart, setcookie: "Note that the value portion of the cookie will automatically be urlencoded when you send the cookie, and when it is received, it is automatically decoded and assigned to a variable by the same name as the cookie name. If you don't want this, you can use setrawcookie() <http://www.php.net/manual/en/function.setrawcookie.php> instead if you are using PHP 5."
In terms of the behavior, I think it makes total sense. The only case where it would ever bite you is yours (which is rare because most people wouldn't mix perl and PHP in the same system). Nearly every other case is neatly wrapped up - newbies will find that setting whatever cookies they want just works, regardless of content. Others who are aware of the encoding behavior probably don't care - it's what they'd do manually if PHP didn't do it for them. Even if you use cookies in JavaScript, you'll have to know that certain charaters would have to be escaped, so you'd run escape on your cookie and find that in PHP you don't even have to do anything and it just works. (And more or less vice-versa.)
As far as I'm concerned, that is the mentality of PHP: there's a function called: do_exactly_what_i_want(), and it just works.
I think some of the negativity aimed at you stems from the fact that the behavior has been explained and is quite clear. There isn't much point in arguing what it should be. It is exactly what it is. If you want to argue what the behavior should be, try php-dev. (Making that kind of argument here is like yelling at your neighbor 'cause Vista sucks...assuming Bill Gates isn't your neighbor. :-)

I'm not going to get into the middle of the base64 argument, but I don't think that mixing perl and php is rare. I've seen the mix occasionally crop up up this list, and I know from myself. I've been using Perl for 10 years and PHP for only 2.5. It's inevitable that I'll choose Perl for certain uses and that I'll call the Perl as cgi from pages scripted in PHP. Then there are things which I've already got written in Perl that I also call as cgi from PHP pages. Or operations that are not compiled into all installs of PHP and are standard with Perl, like fork(), and there's nothing you can do about it because you don't have control over the installation. Each language has its strengths. What's true of Perl, I think is probably true of Python as well. There are lots of programmers and web sties that must mix Python and PHP.
