can I use limit to show the 2nd record on without knowing how many more
records there might be?
also, what happens if I set the limit in a mysql statement (LIMIT 5,10), but
there are only 3 results? 7 results?

This looks like a question that could be answered with a 10 second test
query!
Cheers,

My answer would tend to be that you should try it for yourself and
see...
But anyway, without having tried it myself recently, the first question
is that you could use LIMIT (2, 1) and you'd probably get what you're
trying for. As for the second question, you'll only get what records
there are. If your limit excludes all possible results then you'll get
no result (ie. If you use LIMIT(5, 10) and you've only got 3 records,
then you won't get anything back at all. If you've got 7 records then
you'll get the last 3 of them). But in all honesty, you could have
worked this out for yourself fairly quickly with some simple testing of
your own.

Getting down to specifics then:
1) I have a reminder process that
a) uses .htpasswd
b) USes a static file
So I want to:
I) Convert or use said file using a fill in the blank username/password
process on a Web Page
Once in
II) The user have instant access to their reminder list so they could
A) Modify by adding and/or deleting
B) Set up an e-mail reminder time
C) Set up which e-mail address to go to.
Can I do/convert this and SPECIFICAAL how?

This is really a database question rather than a php question and you
haven't said which database you're using so it's hard to give a
definitive answer. In MySQL you'd do something like this:
Select * from some_table where some_condition order by RAND() limit 1;
That would select one random row out of all rows that meet
"some_condition".

When you say,
Order by RAND()
I would think the "Order by" construct expects a column name.
In your case, it gets a decimal value.
How does "Order by" treat decimal values?
Oh, I just checked the manual:
In MySQL Version 3.23, you can, however, do: SELECT * FROM table_name ORDER BY RAND()
I still don't understand how does "Order by" work with a decimal value!!!

Apache 2.0 allows that...
Meanwhile, in *CURRENT* ISP-land :-)
Some ISPs give you *BOTH* Apache as Module (DSO) and as CGI via suExec,
using different extensions.
So for those really critical security pages that need to run as you, use the
.phpcgi (or whatever) extension and leave the rest as "normal" .php
Actually, I don't even know what the extension is that does .phpcgi on my
servers, I just use the ForceType directive to set the mime-type.
It's nice to be able to run a PHP script as "me" when I have to instead of
as "nobody"
Very nice.

Does rdtool allow you to export in commma/tab/whatever delimited format?
Then just use mysql's LOAD DATA INFILE

OK - I can then assume that rdtool is the Ruby Documentation tool? At
least that's what google chucks up. It appears that it produces
documentation in a number of formats. Perhaps if you could be a bit more
specific about exactly what you want to achieve? For example, how is
your data currently formatted? is it just in text files? what sort of
table structure do you want to put it in?

First, may I suggest you keep the discussion on-list, as there may be others there
better
equipped to help you.
My first suggestion, now that you say you are using rrdtool not rdtool:-) would be to
open
the file in which your data is stored and try and work out the structure in which it
is
stored. Then, decide which of that data you need for your purpose, and work from there.

The requirements for this project was that the site is designed for IE5.5
and above with JS turned on. So in this case, using DHTML was fine.

Hi,
I am planning to use PHP to develop some scripts that will need to
create and manipulate html pages. One of the things that will be
created is a DOM tree of the html.
After reading the manual I've found that php supports the event-driven
and dom xml, but with the latter tagged as EXPERIMENTAL. I've also
noticed that as of 4.3.0-dev (which I am using) the api has changed.
So I'd like to know how "experimental" (also stable) this support is and
suggestions regarding this issue and DOM itself.
One of the main issues is that I'll need to cope with html (not xml) and
mostly not "well-formed".
Regards.

Thank god no method can be trusted :) History even less the the
referrer. Just think of the frequency at which people in their offices
clear it to avoid bosses seeing where they surfed while they were
supposed to work...
You'll never get a secure method, and if you do I'll personally report
you to the authority for protection of privacy :) Marketing dotcoms

you can live without knowing where some of the guys came from. Most

Pffft you can't trust Java, JavaScript or anything on the server side at
all. Since it's set by the browser (client) itself, the best you can do is
test for it, and provide a fall back option.
For the bulk of users, this will be okay, because they're on IE. What you
need to be carefull of is what effect your fall back has on the unknown
browsers.
Or design/program without the need to know what they're using :D

1. I don't believe you specified this was a company intranet, but you may
have.
2. Generally it's a good idea to get things right the first time, rather
than assuming that something will always remain in it's current state. I
tend to copy-and-paste a lot of code from one project to another, or
assemble libraries of code. It might be okay for you to say "this code
works for a limited environment, and i'm happy with that", but will you
remember this when:
a) you copy it across to another project
b) the status of the project changes or is extended
c) the project is no longer in your control
If you insist on sticking with this limitation, do yourself and your
co-workers a favour, and ensure you:
a) comment your code well, pointing out the limitation
b) do some minimal (at least) error handling to deal with the fact that it
may not be there
3. The reply WAS helpful, raised some important issues, and IMHO you should
have thanked the poster for being kind enough to point out issues you may
not have thought of. You could have easily replied with "thanks for those
pointers, but I'm less concerned with privacy, since this is a corporate
intranet".
I'm not sure I'd ever help you again, if I'd received a reply such as yours.

This works for me, PHP 4.1.1
Upon first loading the page, I get nothing, but when I click on "go", I get
both referrer address' echoed.
refer.php:
---
<html>
<body>
<A HREF="refer.php">go</a><BR><BR>
Page refered by
<?php
echo $HTTP_REFERER.'<br>';
echo $_SERVER['HTTP_REFERER'].'<br>';
?>
</body>
</html>
---
It's already been said but:
1. are you sure php is working (with other files, and with simple echo
"hello world!"; type stuff)?
2. use this file (phpinfo.php) to test for the existence of HTTP_REFERER:
refer.php:
---

Upon first loading, it will not be set, but when you click go, you have a
referer, and it is set. For me, it's listed under the Apache Environment
heading.
If you still can't get a referrer var after all that, then there's an issue
with your server (are you using apache????) or perhaps the client (browser).
because it *should* be simple.

Some OO languages (notably smalltalk does it) name a difference between
Class methods (and variables) and instance variables. What is "class"
can be used and executed even when lacking any actual instance of the
class.
PHP has not fully implemented this model (we miss class variables, that
is, a value that is common and general to all instances of a given
class) but does have a bit of it.
So :: is mainly used to execute a method without needing to create an
instance for it. If your class "Printer" has a method
"changeCartridge()" you can use Printer::changeCartridge() without the
need of any prior
$myPrinter = new Printer()
That is, you use a class as a common library. This has a limitation in
that you cannot dinamically say $myclass::changeCartridge(), while you
can say:
$a = "printer";
$p = new $a();
$p->changeCartridge();
The operator :: cannot address internal variables directly like -> does
for the simple reason that no variable exists, in the absence of the
instance. Which is why you declare $ signs. :: operator is also handy
when you need to call an overriden method. By saying parent::myMethod()
you call your parent's method, while $this->myMethod would execute the
locally redeclared code.
-> operator can be read (maybe it must be read, I don't know) as
"belongs to". So "this->a" means "the $a that belongs to $this" (the
object in which you are executing class code). -> obviously only applies
to single instances and not to classes.
Hope it was clear.

I'm not a Redhat user, but.... I think you will have to have installed a
source rpm for mysql. You can probably check if you have the include files
installed by doing locate mysql.h to give you the mysql include directory,
possibly something like /var/mysql/include or /usr/local/mysql/include.
Stripping the /include should give you the 'parent' directory under which
both the include files and lib files can be found.

Hi all.
I’ve been fooling around with a LOOP which should show one or more text
string stored in separate rows in a DB. The trick would we to separate
them with commas (,) when there’s another string to show or end it with
a period (.) if no other row is found according to the SELECT criteria.
This is what I have so far:
for ($m=0; $m<$num_rows2; $m++)
{
$row2 = mysql_fetch_array($result2);
echo $row2[devlanguage];
if ($m < $num_rows2)
{
echo ", ";
}
else
{
echo ".";
}
}
The problem is that the LOOP stops as it’s told to do, keeping the ELSE
statement from doing it’s work, resulting in comma separated string as
it should, but also add an extra comma at the end of it instead of a
period. What approach should I use?

Thanks for two things Martin: First for teaching me about the "-1"
operation (which seems logic now) and second, for getting me into the
"?:" operator. I've read something about it in the books, but didn't
tough it was really useful 'till now.
It worked perfectly. C.

Hi all,
I'm looking at a way of encrypting AND decrypting a string (cc#) with a key.
I plan to store the key in a file outside the docroot, and have asked the
ISP for as much advice as possible to protect the key file.
Anyway, since it needs to be encrypted and decrypted with a key, I obviously
can't use the old faithfull md5(), and from my understanding of the manual,
crypt() is also one-way.
Then I found mcrypt_encrypt() and mcrypt_decrypt().
Paraphrasing the samples in the php manual, does the below code achieve what
I want, assuming that the key would usually be stored in a separate file
outside the docroot?
<?
$iv = mcrypt_create_iv (mcrypt_get_iv_size (MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB), MCRYPT_RAND);
$key = "This is a very secret key";
$text = "11112222333344445555";
echo "plain string: {$text}<BR>";
$crypttext = mcrypt_encrypt (MCRYPT_RIJNDAEL_256, $key, $text,
MCRYPT_MODE_ECB, $iv);
echo "encoded string: {$crypttext}<BR>";
$dectext = mcrypt_decrypt (MCRYPT_RIJNDAEL_256, $key, $crypttext,
MCRYPT_MODE_ECB, $iv);
echo "decoded string: {$dectext}<BR>";
?>
I'm getting the following error using 4.1.1:
"Fatal error: Call to undefined function: mcrypt_create_iv() in
/usr/local/apache/htdocs/tests/enc.php on line 3"
Which is confusing, given that the manual says mcrypt_create_iv() is
available in PHP 4.
Any ideas / contributions / pointers?

Looks like your ISP doesn't have mcrypt support. What does phpinfo() show?
General encryption advice -- generate your key using urandom and save it
to your key file. It will be much more secure than anything you can
think up for a good key.

Well, that was on my local test server, which I didn't compile with
mcrypt... so that solves that, but it appears my ISP didn't compile with it
either... so there's very little point in getting my local server working
with it.
What alternatives do I have?

I don't *think* PHP includes any builtin-by-default, non-one-way
encryption functions, but I haven't looked in a long time so I could be
wrong. You might be able to get your ISP to install mcrypt itself which
has a command line utility. Then you could use passthru() I suppose.

base64 doesn't have a key, so anyone could decode the string, which is
obviously not desirable :)
thanks anyway

Did you actually install the mcrypt libs?

The hooks to those functions are there, it still requires that you install the
lib.

Questions coming from those sources are partly understandable.
What I was referring to was the particular case of "I've got an application
that was working perfectly using php X.XX, then I upgraded to php Y.YY and
now it doesn't work anymore".
It is those people who should look before they leap and read before they
upgrade.

It was confusing to me to wonder why from one day to the next the same
scripts stopped working, until I checked the PHP version.

Hi all. I have this DB where I’m storing this sometimes large amount of
text into a TEXT field, but I can’t seem to find the way to BREAK lines
so it won’t make my browser go 3000 pixels wide when that text is
printed. About this, I have two questions:
1) What should I use to break the text into lines at the DB so HTML can
read them fine? and
2) How should I make the TEXT INPUT BOX so the visitor doesn't have to
type <br> or something after 20 words or so? Is there a way that PHP can
count and break text strings by itself prior storing?
