I use Gnuplot every week to graph the statistics of my business. It's
extremely flexible, and will output not only to graphics formats, but to
PDF format, if I'm not mistaken.

gnuplot may be what you want - but it doesn't have php bindings as far
as I know, so you'll have to call it via a system call.
I use Gnuplot every week to graph the statistics of my business. It's
extremely flexible, and will output not only to graphics formats, but to
PDF format, if I'm not mistaken.
I know for a fact it outputs to postscript, as I've used that with TeX
before, so it probably does pdf as well (and if not - pdf is just a
ps2pdf away).

I've looked at the docs and I don't see how exactly it handles "x,y"
plotting. I need the ability to plot multiple lines (which it
obviously does) with wildly varying "x,y" values. It seems that all
of these libraries "cheat" and force common "x" values via the
labels. I need something like the following (all in the same chart):
$line_one_data = [x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y,x,y]
$line_two_data = [x,y,x,y,x,y,x,y]
$line_three_data = [x,y,x,y,x,y,x,y,x,y,x,y,x,y]
$graph->plot($line_one_data,$line_two_data,$line_three_data)
As I said, each "line" has its own set of "x,y", and although they're
all obviously numbers, they don't all have "y" results at the same "x
intervals" so I need to be able to control them independently. Surely
there's something that can accommodate this...?

Michael

I've had a lot of success with flot, but that's a jQuery plugin, so it may
not be exactly what you need. If you're just making graphs for client side
viewing, it ought to be sufficient, though.

Now that I think of it, that's probably how I do it (ps2pdf).

Imagemagick may do it for you. Here is just one example.
http://www.imagemagick.org/Usage/draw/#bezier
Use the PHP API http://docs.php.net/manual/en/book.imagick.php
Here are some simple graph examples: http://valokuva.org/?cat=2&paged=2
The learning curve is a bit steep; but, once you get the hang of it, things work
great.

Sure - the gd library.
Scale the x/y position according to your needs.

Well, I was trying to avoid building from scratch, but you may be
right. I'm surprised no one else has need for an intuitive setup of
this nature.

I bought PHP & MySQL for DUMMIES and it shows me how to use special
characters for pattern matching and I've figured out the basics of using
preg_replace to replace pattern matches. What I am having trouble with,
though, is figuring out how to replace anything that does not match the
pattern. For example, I want to replace anything that is NOT an
alphanumeric character. Any help would be appreciated. Thanks.

Oh yeah - not sure if spaces are considered alphanumeric or not, but I need

Hey Ben,
to replace everything thats not alphanumeric, use the following statement:
$output = preg_replace('/[^[:alnum:]]/', '', $input);

Is your webserver listening for https requests? Port 443, check it
with "netstat -ltn". Or check your "listen.conf" file.

By "not found" do you mean a 404 error from the https domain?
If so, then you probably just have the DocumentRoot directive set up
incorrectly for your secure domain.

Thanks, you are right. I used php.exe -v to confirm cgi version.
My query is what parameter do I use to specify host and port? That will have
the same effect as -b in php5.
Sorry if I didn't make it clear.

in php4,php.exe is the cgi version for default,and php-cli is the cli

I'm running my test server on Windows XP SP3 and have been successfully
running PHP 5 for some time using:
php-cgi.exe -b 127.0.0.1:10000
My live server is running on PHP 4.4 and that gives an incompatibility risk
in problem solving. So I've removed PHP 5 on my test server and have
installed PHP 4.4.9 but I can't find how I set host and port in php.
Running php -v has confirmed that this is the cgi-fcgi version.
I'm sure it's simple but I'm being driven nuts.

Hello to all,
please i'm new PHP and trying to display some records from my db using
dreamweaver.
I have 2 tables ( Subjects and Pages) where Subjects is the parent and Pages
is the child.
I want to get all pages belonging to each subject but my query gives me all
pages under the first result of the query.
How can I get only pages of each subject under it's own ID ( parent + it's
child)?
I'll include my code for better reference.

Agree with PJ here:
More likely, you go live and the boss says "Can you make that look more like
...?"
"Er, yes, but it totally stuffs the whole design..."
Evolution was *not* carefully thought out - that would be Intelligent Design

If only it were that simple.
When one is developing, one is always changing. And even when you're
finally "live and on the air", you will still be changing or else your
site will die before your client gets a chance to see all you can offer.
It's a matter of evolution and adaptation, Darwin. ;-)
I understand clients changing their minds in mid-stream and wanting
things to be different. That's Okay, because they pay for it --
PROVIDED -- that a meeting of the minds was made with the last layout.
So, before any change is made to the current layout, an agreement
must be made as to what that change is going to be. Anything else
(i.e., let's see if I like it) is going to be very time consuming on
your part.
Cheers,
tedd

Update.
Hello Everyone,
First of all, thank you all for your input. I ran a sinmple test using the
suggestions you gave me and and require_once.
Using firebug to test the output, I got an internal server error. I found
out what the problem was.
What I am doing is I have classes which represent the objects, another
class containing the functions. From the function class I create an instance
of each object, manipulate the information, return the HTML result. Finally
I have a runner class that creates an instance of the function class, calls
the function required and outputs the information.
What the problem was for some reason I was did not create an instance of the
function class, just was calling the function. Well by creating the runner
class I solved the problem.
Thanks all for your help.
Regards
Julian

Hi,
If you want to develop a professional business - enterprise application I
suggest you research books related to Database Design and Development, and
Business Systems Analysis.
UML or Unified Modeling Language will help you with database design and
system design. ERD - Entity Relationship Diagrams are the bassis of
understading weather you have a good dtabse design. The RDBMS - Relational
Database Management System.
Other models will help you understand the flow of your programme before you
start and development. Inorder to have a good system you have to have a good
design.
A GOOD DESIGN IS THE BASIS OF EVERYHTHING.
Through this you will learn other things such as SDLC - Software Develpment
Life Cycle. There are many diffrent models you may use to develop an
profesional application. In the end its up to you to choose.
Regards
Julian

HI All,
Has anyone used Google Calendar (of course via PHP) to allow clients
to schedule appointments from the business's webpage? If so, would
you please tell me how you made it so it would only show the client
times which were available and of course not listing private client
details?
Thanks,
