Hello, I just set up a test box for PHP/MySQL on a WinXP box and now I'm having trouble with variables passed to browser from a link. For example I have a link that outputs this: http://localhost/index.php?team=CF10b. Now the CF10b cannot be user in the code like it should.

But that will just give you .0. If you have 192.168.100.232 it will return 32. You have to check where the . is and then take the substring from that. Use strpos or similar for that (I do not know if that can check backwards) -Original Message- From: Rob W.

Remove the last two characters of a string?
$shorterString = substr($string, 0, -2);
Whether that's really what you want to be doing with an IP address is up to
you.
substr will remove the last two characters from a string, as mentioned
above.
If you want to remove the last byte from an IP address (which could be
.0, .10, or .100) I would suggest:
$ip = 192.168.100.0;
$ip = explode ('.', $ip);
array_pop ($ip);
$ip = implode ('.', $ip);
With PHP 5.1 and up, explode accepts a negative limit, which would
simplify things.

RE: [PHP] When is z != z ?

-- it's not!
Yes it is. The ++ operator generates that sequence when applied to a string,
and nothing you can say or do will alter that fact.
You're trying to treat the 2nd and 3rd elements of the for () statement as an
integrated unit, but they're not - the 2nd element generates the elements of
the sequence in whatever order it generates in, and the 3rd element simply
applies a test to the generated values and causes the sequence to stop the
first time the test fails -- it's not in any way a limiter for what values will
be generated.
Using simple integers, I could code something like this, which would exhibit
similar properties:
for ($i=0; $i=($i+7)%100; $i99)
The expression $i=($i+7)%100 is a generator for all integers in the set
[0,100], but in a non-linear order; the test $i99 will cause the loop to stop
part way through the generated sequence, before some of the values which would
satisfy the test have been produced.
You can't say that a and aaa are members of a set
identified as z and then step through all the members of
that population (an infinite group) and not include aaa --
UNLESS -- you arbitrarily determine an end point for a much
smaller sub-set.
See argument above: you're not stepping through all members of the set z --
or even, as in the original loop, = z -- you're stepping through all members
of the set of strings containing any number of the characters [a-z] in any
combination, in the order defined by the ++ operator, and terminating on the
first generated element which is *not* = z. There's nothing in there that
says you have to generate *all* strings = z before terminating -- just that
you stop on generating one that isn't.
Now, unless, there is something that I don't see, which
certainly could be the case, then php designers could have
just as easily ended the loop at z and dispensed with this
quirk all together.
Well, if the quirk were eliminated by making z++ be the next character in the
ASCII sequence, the loop would still not end at z -- it would end on
encountering { (if I remember my ASCII correctly).
Besides, what's the point of having 676 character between a
and z? Is there one?
No. And there aren't. There are 676 *strings, of length 1 and 2, as generated
by the ++ operator.
You have to remember that there is no such type as 'character' in PHP -- just
strings of length 1. And strings don't (necessarily) behave like characters.
But this is the way it is and I except that -- but as Dirty
Harry once said A man's got to know his limitations -- this
not only applies to men and programmers, but also for
languages as well.
For example, the Unicode issue was raised during this
discussion -- if php doesn't consider the numeric
relationship of characters, then I see a big problem waiting
in the wings. Because if we're having these types of
discussions with just considering 00-7F characters, then I
can only guess at what's going to happen when we start
considering 00-FF code-points.
Well, the PHP manual says: Note that character variables can be incremented
but not decremented and even so only plain ASCII characters (a-z and A-Z) are
supported. If that continues to be the case, then the Unicode argument may be
moot.
Cheers!

[PHP] Re: When is z != z ?
I love this thread. Who'da thunk alphabets could be so much fun? FWIW: Different language, different rules - to do 'letter math', letters must be converted to their ASCII number value, add one, convert back to a letter. The set of allowed ASCII numbers is limited to (I think) 256 and 'real' letters are a subset of that collection. Going from a-z was easy. Once you hit z, you reverted character 1 to a, then looped a-z for character 2, repeat as required. There were only a couple of ways to evaluate a string's 'size'; alphabetical and length. Each comparison generated different results and one had to choose the comparison method based on the particular requirements. In order to convert a string to some numeric value, I believe I had to do it letter-by-letter and derive my own 'value' for the string which would be mostly useless. While the specific language methods differ from PHP (the language did not allow anything like 'a'++ so this particular discussion couldn't happen), it doesn't seem to me that the philosophical underpinnings are all that different - letters are special. They look and behave differently depending on the particular microscope you happen to be using.

Because if we're having these types of discussions with just considering 00-7F characters, then I can only guess at what's going to happen when we start considering 00-FF code-points. Now, was that enough said? :-) I don't think you really understand this. and are collation operators when they operate on strings. They have absolutely nothing to do with the numeric values of the characters. What's to understand? It's the pecking order of strings -- it's the system of how one sorts strings. It's the way I tried to order my books in college. We've been doing it all our life and now you think I don't understand how to sort stuff? It's not the white and colored clothes thing my wife keeps talking about, is it? Look, I understand collation. I also understand that collation is different for different languages and for different needs. In some cases, greatly different. The point of this discussion was how php collates/sorts or otherwise orders characters/strings when given the operation to increment from a to z. As this thread has demonstrated, there's a wide range of expectations as to how that should happen. The reference you provided touches upon some of the problems that collation faces when trying to develop collation systems for different needs. This discussion was no different. It just so happens that in English iso-8859-1 there is a 1:1 relationship between the numeric values and the collation order, but you can think of that as dumb luck. No, English iso-8859-1 was designed to conform to the ASCII standard-- the same as Unicode and other standards that followed. It's not dumb luck to make standards backward compatible, it's by good design. Considering that you're dealing with English iso-8895 and ASCII (developed by American Standard Code), then I think the connection between numeric values and collation went hand-in-hand by design. It was not by accident. It's just too bad that the powers-the-be at the time didn't realize that 7-bit wouldn't cover everything to come in the near future. To better understand this, I suggest you start reading here: http://icu.sourceforge.net/userguide/Collate_Intro.html Note one of the points on that page. That in Lithuanian 'y' falls between 'i' and 'k'. So even without going into Unicode and just using low-ascii, you have these issues. I don't have these issues because I'm not Lithuanian. If a Lithuanian php programmer wants y to fall between i and k in a loop, then good luck -- for I can't get it to stop when it passes z -- which I think it should. But, as I am aware, there is no low-ASCII, there is no high-ASCII, there is simply ASCII. While it is common to use the term of extended-ASCII, it's a misnomer because American Standards Association had nothing to do with establishing/defining any character above DEC 126. The above example you referenced is simply one of many and demonstrates that the collation problem is very complex. You should look into how Unicode performs canonical ordering in combining characters such as using an accent, umlaut, or cedilla as well as how that combination affects collation in different languages as stated in your reference. You will see that canonical ordering algorithm is numeric. Yes, I'm very aware of Unicode. I'm aware enough to know that they have assigned numerical equivalents to every glyph known to man including those combining glyphs such as those mentioned above to produce combination characters. When I say every glyph known to man, that includes much more than language specific glyphs. I'm also aware of IDNS and how they implement Unicode, which is not inclusive. Take for example case mapping which IDNS simply translates all of what they perceive to be uppercase to lowercase. Some characters are combination characters when lowercase and a single character when uppercase, thus there is no lowercase representation for the uppercase character. Oops, I just lost the 16th century (Roller Ball). Now, I can appreciate the problems facing php considering that it has to deal with not only Unicode, but with also with the IDNS when addressing Unicode and the Internet. But that problem is not going to be solved by ignoring that Unicode code-points have numeric (and other) values. I would think that serious collation systems use numeric values in some fashion in their algorithms -- don't they? If not, please explain how they detect differences between characters and group them into collation tables. Now, until we get to PHP 6, we don't have decent Unicode support and we don't have LOCALE-aware operators. You will have to manually use strcoll() to get them, but that is going to change and you will have the

[PHP] Getting totals
Ok, Here is my next problem.

192.168.100.0 all the way though 255
along with
192.168.101.0 though 255
and
192.168.102.0 though 255
and soforth
My problem is, is i'm trying to figure out a pattern to match so I can count
how many ip's are in each block and display them.
So far what I have gotten is a stristr match but it's not working correctly. I
have a variable that basically weed's out the last digits of the ip it's self
from help previously
So my code so far is:
if (stristr($block,$address)) {
$count_ip++;
}
$block would == 192.168.100
$address would == 192.168.100.0 - 255
Any help would be appricated.

This isbecause you're using the wrong tool for the job. Don't blame the
tool, blame the user of the tool. if you want to loop from 'a' to 'z'
then use chr() and ord().
?php
for( $i = ord( 'a' ); $i = ord( 'z' ); $i++ )
{
echo Nuff said!\n;
}
?

Tedd,
The discussion of PHP strings has been interesting; thanks for sparking that.
Of course, your subject line to the contrary, it's not that z !=
z, it's that storing an alphabetic character assumed to be a single
byte in a variable and then incrementing it can result in a two-byte
result. I find it plausible that the statement $a = a produces a
two-byte result in the first place, we just don't notice it because
the second byte is turned sideways and is very, very skinny.
I assume you know (but I'll state it anyway for the record) that to
avoid the problems you've encountered by trying to treat apparently
multi-byte PHP string variables like one-byte numerics, you can
simply use numerics themselves:
for ($i = ord(a); $i = ord(z); $i++)
{
echo chr($i);
}
ord() and chr() being the PHP functions to yield the numeric value of
a character and the ASCII character of a numeric value:
http://php.net/ord http://php.net/chr
To save that hard-working server a few machine cycles, one would
presumably store ord(z) in a variable before the loop began and
test for that each iteration.
Warm regards,
Paul

If php is supposed to be open source, doesn't that mean that people can voice

[PHP] Weird Safari Stalling Issues Sessions?
Dear All,
I'm having a very frustrating issue w/ Apples Safari web browser.
The browser will stall when I try and initiate a sessions on login .
So on our login page we validate the username and password and start the
session.
When a Safari user attempts to login the Safari wheel just spins and spins.
I've restarted the browser, cleared the cache , cookies and history to no
avail. Putting in a bad username password causes no lockup and the proper
bad auth page is shown.
I've added:
// attempt to fix Safari issue
header ('Expires: 0');
header ('Pragma: no-cache');
to the header and still no luck.
I've found many similar incidents on the WWW with no real solutions.
Has anyone had similar issues and found a workaround for this problem?
I believe this is a Safari issue and not a PHP problem. But I'm hoping
someone has created a solution w/ PHP.

Re: [PHP] When is z != z ?
Tedd,
The discussion of PHP strings has been interesting; thanks for sparking that.
Of course, your subject line to the contrary, it's not that z != z, it's
that storing an alphabetic character assumed to be a single byte in a variable
and then incrementing it can result in a two-byte result. I find it plausible
that the statement $a = a produces a two-byte result in the first place, we
just don't notice it because the second byte is turned sideways and is very,
very skinny.
I assume you know (but I'll state it anyway for the record) that to avoid the
problems you've encountered by trying to treat apparently multi-byte PHP
string variables like one-byte numerics, you can simply use numerics
themselves:
for ($i = ord(a); $i = ord(z); $i++)
{
echo chr($i);
}
ord() and chr() being the PHP functions to yield the numeric value of a
character and the ASCII character of a numeric value:
http://php.net/ord http://php.net/chr
To save that hard-working server a few machine cycles, one would presumably
store ord(z) in a variable before the loop began and test for that each
iteration.
Warm regards,
Paul
Paul:
And I thank you for your reply -- you've been much kinder than most (on and
off-list). :-)
True the subject line was a bit misleading, but that was intentional. Bait
causes more fish to rise.
I've received the answer several times over since I posted the problem, but I
wasn't looking for a solution because I already had one.
What I was looking for was an explanation, which I got. I hope the answer
remains with me longer than the bandages do. Asking questions in this group is
like trying to feed alligators while being waist-deep in the swamp. :-)
Thanks.

Ok, Here is my next problem.
Inside my database, I have a list of ip's of about 10 blocks
192.168.100.0 all the way though 255
along with
192.168.101.0 though 255
and
192.168.102.0 though 255
and soforth
My problem is, is i'm trying to figure out a pattern to match so I
can count how many ip's are in each block and display them.
So far what I have gotten is a stristr match but it's not working
correctly. I have a variable that basically weed's out the last
digits of the ip it's self from help previously
So my code so far is:
if (stristr($block,$address)) {
$count_ip++;
}
$block would == 192.168.100
$address would == 192.168.100.0 - 255
Any help would be appricated.

Turn off register globals. Now. It is a HUGE security hole.
it is NOT by definition a security hole - the problem arises from scripts
that don't bother to initialize all their variable before using them,
which allows blackhats to possibly interfere with the intended functionality
of a script.
e.g.
?
// myfile.php
if (chkCleanRequired()) {
$delete = true;
}
if ($delete) doDeleteRoutines();
?
which could be hacked like so (if register_globals was on):
somedomain.tld/myfile.php?delete=1
that said having register_globals turned on is bad practice -
turning it off and using $_GET, $_POST and $_REQUEST is preferred and
offers a buffer against silly mistakes related to not initializing
variables properly ...
in addition a number of members of the core php
dev team are in the process of finalizing a data filtering extension
[which I believe will be included in php by default] that will take
data filtering to a whole other level in php ... soon even the use of
the raw data in $_POST, $_GET, et al will be discouraged in favor of
using the api provided by the filter extension... I'm so looking forward to
that :-)
You do NOT need it turned on to use $_GET or the other superglobals, and
there is in fact no reason at all to EVER turn it on. The only
conceivable reason that someone would enable it is for an old badly
written script, and in that case one has to question why they are
running an old badly written script :)
there are plenty of legacy codebases out there that rely on register_globals
AND are quite adequate regarding protection from potential problems arising
from register_globals being turned on.

$orderedSequence = array();
for ($i = $start; $i = $end; $i++) {
$orderedSequence[] = $i;

Supposedly this function would return an ordered sequence of objects, which

No problem, doesn't really sound like ranting to me. But I think the
main problem some people are having is understanding that there are two
sequences in question here and not one. There is the sequence generated
by the incrementation operator, and there is the sequence of all
possible strings in their sorted order. Combining the semantics of the
two sequences does not necessarily leave you with the semantics of one
or the other.
Cheers,
Rob.

pushes the submit button the generated url should be
...?name=firstname_lastname.
Is this possible and how?
Thank you for helping a php newbie.

[PHP] starting shell script on server: defer acces when running
I have a shell script I want to run which generates an html page after it runs some tests on the software I am writing. I call the script with exec(…); The tests take more than 2 minutes to complete. If I try to run more than one test at the same time: trouble. I want to solve this by checking somehow whether the tests are running. If so, then the php code just waits until the running test are complete, referring the second user to the same results page as the first. Ideas anyone? -- No virus found in this outgoing message.

I'm not entirely certain as to how you'd do this, but I've included what I

httpd.conf instead of .htaccess - there are performance concerns that

[PHP] Replacing text of a DOM text node
Hello! Basically, I am working on a script that is supposed to convert table data from metric to imperial data. I want to pare XHTML pages (containing up to three different tables) with the PHP DOM functions in order to be able to access and manipulate the tables one by one. Parsing and retrieving table headers and cells is not the problem. The problem right now is how to replace data in the headers. Here is a rather simplified example of a table I want to convert: Header contains: Product | Lenght br / mm | Width br /mm | Weight br / kg As you can see, table headers can contain one or more words and a (optional) line break. Currently, I am able to get all headers as a list of nodes from where I can access all headers one by one. But when I try to replace some content like this: # $nodeElement contains the current text node from a header $str = some new content; $new_header_element = $doc - createTextNode ( $str ); $nodeElement - parentNode - replaceChild ( $new_element, $nodeElement ); .. I am able to replace e.g. Product, Length or Width. I am not able to access / replace anything after the line-break. Why? I have already tested to get to this content with $nodeElement - childNodes; but this will throw an error. Hopefully, I was able to explain my problem to you... OOP and especially working with the DOM functions are still very new to me, so please be patient with me. If anyone has an idea, I would love to hear about it. Otherwise, there might be someone how can point me to some good on-line documentation / tutorials regarding PHP DOM functions.

Check out:

Tedd,
Thank you for the reply.
The weird thing is my session code works great. Until a few months ago it
worked great in Safari also.
All the code I generate is tested in Safari,IE and Firefox.
I'm assuming this is a Safari related issue. But I was hoping someone had
a workaround or had seen similar issues.
So if anyone has seen this or has sometype of solution please let me know.
Thank you,

Your Regex should probably be pretty simple...
Something like:

Though god only knows what your db needs to grok that, or if it even
CAN do that...
So far what I have gotten is a stristr match but it's not working
correctly. I have a variable that basically weed's out the last digits
of the ip it's self from help previously
So my code so far is:
Oh.
Well if you want to do this in PHP in a loop, instead of in the DB
like it should be done, check out http://php.net/preg_match and find
an example of IP quads in there somewhere.
if (stristr($block,$address)) {
$count_ip++;
}
$block would == 192.168.100
$address would == 192.168.100.0 - 255
Any help would be appricated.

[PHP] Re: Getting totals
Well, if I understood correctly, and the IP's first 3 segments are all
of the same length, the you could do something like this (MySQL)
SELECT
SUBSTRING(ip, 1, 11) AS ip,
COUNT(1) AS cantidad
FROM tabla
GROUP BY ip
Now, if you don't intend to do this in SQL, then you could try some of
the other suggestions.

strstr(192.168.100,192.168.100.10)

It's just like 1 thru 9 followed by 10, except that it is NOT an ordered set in terms of and In my last post I showed an actual sequence which is debatable. It could be interpreted that the infinite set starts at a, aa, aaa,... and never reaches b. Oddly enough, this could be viewed in all sorts of ways. It's probably best if we don't look at characters as numbers. EXACTLY! They aren't numbers. So doing ++ to one of them, doesn't necessarily end up with an ordered set. Rasmus chose to make ++ be useful for generating sensible sequential file names, not sensible ordered strings. Well, it does other sequences too and the first priority is always to try to convert to a number. For example, try incrementing the following strings: 1, 1.5, 0xf8, 10e2 These all end up being converted to numbers (integers or floats as appropriate) and hopefully they end up with the value everyone would expect. Since the Web by definition is untyped, all we get passed around between the browser and the server are strings, so we need to make 123 passed as a string behave as the number 123 as much as we can. Otherwise we would spend a lot of time type juggling. Having 123++ not end up being 124 but instead do something to increment the ascii values behind the string instead would create chaos. So, given that in any instance where we can convert the string to a number ++ logically increments that number by 1 spot in the numeric sequence. It follows that anywhere we can determine a logical sequence for the string, ++ should increment that sequence. The other option would be that anything that can't be converted to a number would end up being 0, and whatever++ would always be 1. Or we try to do something a bit more creative which always runs the risk of surprising people. In this case a2++ becomes a3 and c9++ becomes d0. If we have a character that doesn't infer any sort of logical sequence, like then the ++ does nothing. So ++ stays at . However 3 becomes 4 and b++ becomes c. 99z++ becomes 100a and 1z9z9z++ becomes 2a0a0a and yes, of course z++ becomes aa which is what caused this entire thread. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Like I said before, strstr's argument list is haystack (what to
search in) first and then needle (what to search for). Therefore,
you need to have:
strstr($address, $block);

Re: [PHP] Getting totals
I got the fix, strstr didnt work right because it was relaying more than
just what I was thinking.
Here is the fix.
$value=array(strstr($block, $address));
foreach ($value as $var) {
$block_total_ip++;
}

[PHP] Problem with form
Guys I'm getting the following problem:
I have a form that asks for one variable that goes into the input box,
this box is named chapter, and the box is in a form that is submited
to another php, and this php should receive this variable and I should
be abble to access it thru $chapter, but when I try to use the
variable $chapter I get the following error:
Notice: Undefined variable: chapter in c:\arquivos de
programas\easyphp1-8\www\teste.php on line 6
This variable is concatenated into a string and is used to retrieve a
certain page from a domain, if I initialize the variable in the second
php script it goes ok, but if I try to use the one that should be
passed thru the form I get the error above. Does anybody know what I'm
doing wrong?
The second script is bellow so you can understand my problem thank you guys:
?
//$chapter = 1;
$urlChapter = '/'.$chapter.'/';
$url = http://www.domain.com/s/2784825.$urlChapter;;
$texto = file($url);
$result2 = count($texto);
$i = 0;
while ($i $result2)
{
echo $texto[$i];
$i++;
}
?

You are relying on register_globals being set to on. Instead use the
more secure method of retrieving your submitted data from $_GET or
$_POST (depending on which method your form is set to use). You can
also use $_REQUEST if you don't care from whence the data was submitted
(but you should care :).
Cheers,
Rob.
