By submitting the form probably...?

You haven't provided any code, or actual problems. If you wrote the code
correctly within calculate.php you wouldn't be asking this question.
Upon refresh/reload of index.php, calculate.php should be updating your
cookie.

When you set a cookie, it is sent *TO* the browser, to be sent *back* in
the *NEXT* HTTP request.

The browser itself does not have access to the cookies, so you can't, say,
use javaScript to do calculations with them.

The Cookies you just *sent* at the top of your script have not been sent
*back* yet -- But since you have the values at the top of the script, you
can use those same values in some variables to provide whatever
calculations you want.

Hope that helps you sort things out...

You'll need calculate.php to setcookie(). Then on the *next* index.php
invocation $_COOKIE['yourcookie'] should get updated with the value you
wrote to the cookie.

The only way to "refresh" calculate.php is to finish output to the
browser and then refresh index.php. Although perhaps using a session is
better than using a cookie in this case?

I guess I don't grok your problem because the way you described it seems
trivial.

<?php

function calculate($var) { return "The value of var is $var"; }

/** From the browser / cookie / whatever */
$input = 11;
$output = calculate($input);
setcookie('yourcookie', $output);

/** And now you do whatever you want with output */
var_dump($output);

Hello,

This is the only "programming" list I participate in so that is why I'm
asking my question here. I hope no one objects greatly!

So my question has to do with planning a project (not necessarily a
website in general, but a programming project specifically). I've got
Visio 2003 and a pad of paper with a pencil. I'm pretty much willing to
try out different methods although I prefer a visual approach.

I've googled on this subject quite a bit in the past but haven't really
found anything that satisfies me. That is, I've found some short
documents on flow charting, but nothing directly related to programming
(and what symbols to use, or how detailed to get). I've also tried just
writing out some pseudo-code but that always tends to get a little messy
when I try it.

If I start writing code outright I find myself rethinking a lot stuff
once I'm already pretty entrenched in what I've got. Of course this
turns into being a major pain going back and revamping stuff.

Anyway, I'd like to hear some feedback from the audience as far as what
works/doesn't work for you as well as some keyword recommendations that
I can feed Google with.

Thanks,
Chris.

:-)

Seriously, any time I try to plan something out for any kind of
programming, I find that a nice big desk surface, and a pencil and paper
are the best tools.

After I've got things worked out on paper, with all the scratch-outs,
circles and arrows, and am happy with the basic design, I then type up
something in plain text as my "final" draft.

Not claiming I don't end up revising the hell out of it in development,
mind you, but it seems to work, and I catch all the stuff I have enough
smarts to anticipate.

The stuff I can't anticipate, well, there you are, eh?

I've tried Visio and all that stuff, and find myself wasting *WAY* more
time lining up the damn boxes than actually thinking about what I want to
*do*.

YMMV

All true.

And having read Jason's email I think I'll try to put that graphical
process into practice. Doesn't have to be in Visio considering...

Agreed.

Thanks,
Chris.

I'm with Richard - lots of scrap paper, couple of nice sharp HB pencils ...
let it ferment a bit,
then pseudocode in a plain text editor.

As for the graphics - well, I have an old template used in Introductory
Basic for the Control Data Corporation <whatever>. Haven't used it since
about 1970, but then keypunch machines have been scarce.

For the most part if you're working on this alone, then the pencil,
paper approach is probably the best. It doesn't matter how carefully you
plan your architecture you WILL want to change it and then not only will
you have to change your code, but that big fancy time-sucking, visio
diagram.

On the other hand if you are working with a bunch of people (and this is
especially true if they are remote from one another) then you really
MUST have some kind of clear and concise plan in place or you'll be
stepping all over each other.

Cheers,
Rob.

Hi, i want to add my site a more specific download system. The redirecting is now done by directly
giving the path of the file to variable. I want to do it over an id number.
(now: dl.php?rel=/files/somefile.zip, i want: dl.php?id=64b3j283) The file path and id is read
from mysql table. System is now; it matches from table and lets visitor to download but putting
this kind of path is something useless. Download script is just used for counting the hit but for
example i want to rename the file while giving to visitor instead of letting user to learn where
it is stored and its real name, The_Justice_by_Someone_MyDomain_com.zip looks like what i want to
have. I tried this system with header("Location: ......"); but it just opened a new page and
nothing happened else. For example if visitor uses FlashGet i want him to see just an address
which doesnt involve the real path and name. If any body can help me, please.. Thanx a lot..

Some snippets of ideas that should be useful to you:

Build a table that relates secret tokens to filenames:

create table downloads (
  token char(32) unique not null primary key,
  filename varchar(255),
  whattime time_stamp
);

Generate a secret token:
$token = md5(uniqid(rand(), true));

Put the file they asked for and the token in the table:
$query = "insert into downloads (token, filename) values ('$token',
'$download')";

You're on your own for the rest.

Thanx for answer but i ve already done this part of job. I have got generated tokens for files but
at the time of download i can not use the token instead of file name and path. I want to redirect
to file while showing a senseless token but i can not imagine how to do it..

How about setting up symbolic links on the server in a tmp directory.
You could use the values from your database table to create the sym
links. Have the sym link be the token name and then have it linked to
the real file name. You could then have a cron job running to clear the
sym links at set intervals. I do this for a Royalty Free stock site and
it works great.

Subject: Building modular applications (long)

Hello,

So I was thinking about building some modularity into future projects
and wanted to bounce some ideas off my fellow list members.

My definition of "modular application" is: A modular application is one
that can have it's major functions added/removed with the click of a
button, or the creating/deleting of a file without breaking the
application on any level. The user should be able to add/remove a
module* from the filesystem and have the application update itself
automatically without any (or very little) interaction with the user of
the application.

For example, here is what I've come up with at this point for how a
modular application could be built.

First of all there would need to be some kind of script that
controls/integrats/manages the individual modules. I imagine this task
to be performed within an include file that is included at the top of
every file in the application (let's call it adjuster.php). This include
file would determine how to build the main menu based on certain factors
within the applications directory tree. Said another way, this file
would take an inventory of the available modules and build a menu based
on what it found. In this way a module could be added/removed without
any interaction** from the user and the menu would update automatically.

This in and of itself is not difficult. What I think the difficult part
of it will be is finding the appropriate way to construct modules. At
this point I'm imaging a directory called modules/ where each directory
within the modules/ directory is a module itself. It would contain all
the classes and functions associated with that module as well as a
definition file for that module (could be a simple .txt file).
Adjuster.php would read the modules/ directory and recursively discover
each module and then build the main menu accordingly.

Having said all that I think what I'm looking for is some feedback from
experienced person(s) on the list with building modular applications. I
can see this being really helpful for something like a shopping cart,
CRM, or CMS app.

Thanks,
Chris.

* In the short time I've been thinking about what a "module" is I've
determined it to be one of a few things (or a combination thereof). A
module could be (a) a single file, (b) a set of files, or (c) a
directory containing one or more files and/or directories.

** Not having any interaction with the user does not have to be a
requirement, but it would sure be helpful when upgrading the
application. For example: Customer comes to your website, buys a new
module (or downloads for free, however you choose to license the
software), and simply adds it to the module repository. Yadda yadda
yadda, a new, full functional menu option is available.

p.s. Are there any lists out there that deal with programming in
general?

I haven't encountered this problem before. However, most of the time
when I run into a problem like this it's because there is a missing
library that is required *in addition to* the library for the extension.

Accoding to the source, these two functions require
something to exist:

#ifdef PHP_ODBC_HAVE_FETCH_HASH
PHP_FUNCTION(odbc_fetch_array);
PHP_FUNCTION(odbc_fetch_object);
#endif

Elsewhere in the source is this:

#if defined(HAVE_DBMAKER) || defined(PHP_WIN32) ||
defined(HAVE_IBMDB2) || defined(HAVE_UNIXODBC)
# define PHP_ODBC_HAVE_FETCH_HASH 1
#endif

So you need to meet one of the above requirements to have
those two functions available.

According to the changelog, many of these checks were added
in early 2003 (4.3.2) not that this has to do with you but
when documented these should be taken into account. I'll add
this documentation later this week :)

Philip

It works for me, but if it's not working for you...

function my_error_log($text){
$lines = explode("\n");

Have you considered using PHP to write JavaScript that will build the

If the arrays are at all predictable from a smaller set of data, this can
cut your bandwidth.

One starts to wonder if you're not maybe just going down the wrong path
entirely...

No. It would only invalidate any "saved" logins or passwords from the old
realm being managed by the browser.

Different realm == different login/credentials needed.

That's your ISP being silly, not PHP 4.3.10 "changing"

That said, HTTP Authentication WILL NOT WORK with CGI.

It is disabled in PHP source because, because your password would be
transmitted insecurely from Apache to PHP, and the PHP Team is not willing
to do that for obvious reasons.

Get your host to go back to PHP as Module, or switch to a form login.

I could be *WAAAAAY* wrong, but I thought nobody ever bothered with Digest
Auth because, errrr.

It's not better/safer than HTTP Auth?

You might as well go with SSL if you go to that much trouble?

Not enough browsers support it?

Okay, so clearly I don't remember why I thought this.

Google for "PHP HTTP Digest Authentication" and see what turns up...

But don't be surprised if the answer is "Not supported"

"HTTP Basic Authorization" send login:password in clear text (only
base64 encoded) so it can be 'eavesdropped'
in
"HTTP Digest Authorization" password is hashed md5(...) co can not be

This is an incorrect way to try to flock a file for writing.

You should:
1) Open the file for READING.
2) flock that file handle, so only YOU have access to that file.
3) Re-open the file for WRITING, now that you have control.
4) Write your data
5) Release the lock.

Your application, as it stands now, has a race condition between the open
for writing and the flock, which sooner or later, WILL bite you in the
ass.

Probably.

Maybe.

If $filestr is small enough, the Linux OS has locking built-in. Windows
may or may not (and I don't care enough about Windows to remember, much
less look it up). FreeBSD and other OSes may or may not also have locking
at OS layer. I wouldn't rely on it, though, since it's trivial to do the
5 steps above.

Dollars to doughnuts there is *NO* /images directory on your machine.

There might be a /www/iceagents.com/public_html/images directory, or there
might be a /home/whitley/public_html/images directory or something like
that, but almost for sure there ain't no /images directory on your
machine.

If there *IS* such a directory, PHP needs write access to it.

If that's a MySQL error, you're gonna be WAY better off asking on the
MySQL mailing lists...

At a guess, you're either trying to send a query that's WAAAAY too long,
or get back waaay too much data, or your database server and internet
server aren't doing TCP/IP packets nicely, or...

It could mean a whole lot of things, actually.

Google for the error message, and 'max_allowed_packet' and see what turns up.

Let's try it this way:
What's the other server?

Did you read their FAQ and their documentation?

Here are functions that, depending on what you read on the other server,
may be helpful:

http://php.net/file (GET)
http://php.net/fsockopen (POST)
http://php.net/curl (SSL)

The (WORD) indicates which function you would use, at a minimum, if you
find that word in the other server's documentation.

Note that in each case, you *could* use the next function down in my list,
if you wanted to do it the hard way. :-)

YMMV. NAIAA.

The browser is not required to keep more than N cookies.

I think N is 30.

It *also* is not required to keep more than X kilobytes in all the cookies
from your server combined.

X is some reasonable number.

It doesn't matter because...

It's a Bad Idea because it's just more crap going back and forth over HTTP
(slow) and more annoying to those of us who surf with some discretion over
Cookies. If your site sends too many Cookies for me to decide if they are
"okay" or not, buh-bye.

Use session_start() which sends *ONE* cookie, and then you can store
whatever you want in $_SESSION to tie it all to "me"

Some errors are simply too heinous for PHP set_error_handler to catch.

See user notes on php.net/set_error_handler for discussion.

I think that's where it is... Maybe in bugs.php.net

At any rate, if you are hitting one of these errors, it has nothing to do
with your class, and everything to do with what set_error_handler simply
cannot cope with.

If your PHP source code simply cannot be parsed, those errors will not get
caught by set_error_handler.

That could be what's in your class file.

You'd have to tell us the error message and maybe even show us the lines
near the PHP error message.

split does regular expressions.

Where '.' means "any character"

So you *could* do '\\.' instead of '.'

So I could forge a bunch of bounces from somebody else's email account and

You might maybe wanna use some kind of one-time token such as that

you bounce email. The total scum spammmers won't -- Their return address

Hey all,
I just put in a search function for a site using mySql full text, i am
running it on my local server for now.
I am running it on two fields: ad_sub and ad_text

The results i getting are really quite bad, this is how i am testing it out:

1. I wrote an insert statement and looped it 700 times, so i have 700 test
records in the db which are identical
2. I found two words which are in the ad_text of the insert statement and
wrote a search statement like so:

SELECT *,
                MATCH(ad_sub, ad_text) AGAINST('want to') AS score
                FROM blk_ads
            WHERE MATCH(ad_sub, ad_text) AGAINST('want to')
            ORDER BY score DESC LIMIT 0,40;

2a. I have checked many times and this text " want to use a full....." is
present in the ad_text field

but mysql gives me no results.

Reading up on "full-text " I came accross this useful piece of info:
you should add at least 3 rows to the table before you try to match
anything, and what you're searching for should only be contained in one of
the three rows. This is because of the 50% threshold. If you insert only one
row, then now matter what you search for, it is in 50% or more of the rows
in the table, and therefore disregarded

which means because I i getting a match for well over 50% of the
records...its disregarding it.

Now i am in two minds if i should use this or go back to the same old dirty
way...of exploding the search and using LIKE '%%' for each word

Comments/suggestions?

Thanks,
Ryan

FULLTEXT searches are great; it's your testing of them that is poor.
What validity is there is "searching" through X number of identical
records? This isn't a real test at all. Also, FULLTEXT searches are
improved as the number of __different__ records increase.

If you want to see some results, regardless of the 50% threshold, use
the IN BOOLEAN MODE feature. Keep in mind, though, that in your case
any search will return either 0 or 700 results.

Kind of true, but I would have still been happy if it had found some records
rather than 0 results.

Yep, I understood that from reading the docs.

I dont want to do that as its only mysql 4.1+ compatable, I presently DO
have a 4.1 setup....but if we shift hosts...i dont want it to "break" my
code.

Thanks,
Ryan

IN BOOLEAN MODE was added in version 4.0.1 not 4.1, for what it's worth.

If I run this PHP script:

If I turn safe mode on, it gives me a "safe mode is on" warning only about

Anyone know what's wrong? I've been staring at this thing for three days and

hi all

All of a sudden, my local install of Apache has started throwing access
violation errors. It's happening pretty frequently, particularly when
hitting the refresh button on a page generated from POST data, causing a
re-POST, but isn't 100% reproducible.

Anyone else had a problem like this? I couldn't find anything in the
php or apache bug databases that sounded like the same problem.

If anyone has debug mapfiles for the php dlls, or even better, win32
debug builds of 4.3.10, would it be possible to send them to me. I don't
have access to MSVC here, so I can't build them myself :(

Any suggestions welcome!

I'm not that skilled. Just checking with real coders. I'm more of a well-meaning academic who wants to share an idea with other teachers and show them an easy, applicable example of sending score results to a mysql server. It's part of a bigger tutorial:
http://compcanlit.usherbrooke.ca/eslcafe/hotpotatoes/hot-potatoes_104.htm
I'm still working on it.

your example looks pretty solid, but the code above does not escape the
$StudentNumber, $Exercise1, and $Exercise2 variables. If any of these
variables contain data that when placed into the SQL string interferes
with the SQL itself, you'll have unexpected failures and also a security
hole if untrusted users can populate those variables. The solution is
to wrap any strings or untrusted input like that in a call to
mysql_escape_string(), like so:

$sql = "INSERT INTO $table
(StudentNumber,Exercise1,Exercise2) values ('".
mysql_escape_string($StudentNumber)."','".
mysql_escape_string($Exercise1)."','".
mysql_escape_string($Exercise2)."')";

actually, last time I saw something like this was when I prepended a

I am using PHP. I have a registration page where the user has to select his

This is easy to do for a textfield but how do I indicate on the drop down
list which country he originally selected?

Please help.

Set the attribute selected on the country, ie :

<option value="12" selected="selected">United States</option>

This is really a HTML question, not PHP related.

I want a button that resets all my cookies. Can I reset them all with a

/*From the php manual
$arr = array(1, 2, 3, 4);

$_COOKIE is a variable... but you need the key for setcookie(). so you can do:

foreach($_COOKIE as $key => $value){
setcookie("$key","", time()-3600);
}

i know there is the $value bit that we never use, but this is the
simplest form I can think of. can anyone else think of something
better?

Hello,

How can I remove a space character from variable value.

for example:
change
$name = "John Doe";
to
$name = "JohnDoe";

The blank space needs to be removed from the string. How?

Thanks a lot!

Did You search? http://dk.php.net/manual-lookup.php?pattern=replace

Str_replace, ereg_replace, preg_replace is just a few friends, that will
help You. Php.net is Your best friend ;-)

Quote: "> i'm experimenting with php on mandrake 10 and i'm not sure about a few things. first, where should the php.ini file go?"

I think You did indeed.

And I´ll correct my self for the info:

"If You compile PHP there´s a parameter to use:

--with-config-file-path=/usr/local/php.ini"

Skip the php.ini from the _path_ (doh!)
