Hi all:
I'm really new at PHP and will probably embarrass myself many times over
asking questions that have been asked gazillions of times before, so let this
serve as a blanket apology.
Now, to my question. Here's what I'm trying to do. I have a simple
database on my website that I wish to populate with information from various
directories on my local computer. The website is running Linux; my computer is
running Windows XP. Once the data are stored, I want to be able to update the
information as things change on my local computer (not in real time, mind you,
but at my request).
I can set up the database access easily enough, and I know how to both
populate and query it. What I don't know is how to obtain the information from
my local computer via the website. Initially, I'd like to be able to specify
the folder on my local computer to access and whether or not to process any
subfolders that are found. After the data have been added, I'd like the web
application to be able to access the individual folders without having to
specify them again (although I'd still be able to identify new folders to
include in subsequent updates).
I'm not really asking for anyone to write the code for me, but I am looking
for suggestions for PHP functions to use to accomplish the inspection of my
local computer's folders. I'd also need to know what additional information
I'd need to store in the database so that subsequent updates can be automated
(i.e., do I need to somehow store my IP address?).
Any help you can send my way will be greatly appreciated! Thanks in
advance.
Sincerely,
Jon

You will get a cold response from the regulars on this list if you "ask
questions that have been asked gazillions of times before". Friendly
advice: always take a little time to search the archives of this list and
google a bit to see if your question has already been answered. Can you
imagine what this list would be like if every newbie asked the same
questions every day? That said, on to your questions.

You will not be able to do what you propose with a purely PHP solution. PHP
is a server-side technology. That means all the processing is done at the
server, then output to your browser. PHP, to my knowledge, has no way to
inspect your computer's folders. You would need to look to a client-side
technology, like Java, for that.
However, you can upload data to your website using PHP to process the
uploaded file. So, at your convienience, you can have a "Browse" button on
an update page that will allow you to browse and find your data to upload.
After the upload you can have PHP process the uploaded file any way you
wish.
You can also use cron to kick off scheduled tasks with PHP CLI scripts that
will, for instance, open an FTP connection to your machine and download data
files to the server for processing.

Jon,
I don't know how to do this, but it's a bad idea. Can it be done? Probably,
but it is still a bad idea.
Why do you want to:
Expose the contents of your machine to the world?
Make your machine vulnerable to attack via your web application?
Enable a path into the file system on your computer?
I would suggest approaching it the other way - if it's something the world
should see, upload it to the web server. PHP has lots of tools for reading
and traversing directories.
If the uploading task becomes onerous, write a script to run on your local
machine, using whatever language you are comfortable with, to upload all of
the desired content to the web server.
Read some articles on cross site scripting to discover why your original
approach is not a good idea. Here's one:
http://www.cgisecurity.com/articles/xss-faq.shtml
and see the links at the end.

Hi,
You should perhaps look at setting up a web server on your computer. PHP
as stated works server-side and if those folders/files you wish to
transfer reside in the web root, then PHP can process those files.
Perhaps look at how a web based FTP client written in PHP works for how
to copy/move/delete files in PHP. If you can't set up Apache with PHP on
Windows, try something like phpdev5 for a click and use solution.
As for your IP, it won't really matter unless you want the server to
send data back to your computer. If a static IP or hostname is in order,
then they are easy enough to set up even if you are on a dial up
connection.
Regards

Hello List
I've got the following little code:
$formCheck= $_GET['formCheck'];
$SollKombination = $_SESSION['zufall'];
echo "$SollKombination<br>$formCheck";
print gettype($formCheck);
echo "---";
print gettype($SollKombination);
if ($SollKombination == $formCheck){
echo "test";
}
To give you some background: This code is supposed to check if a user has tried
to login via my form.
Which gives me the following output:
ZL0X~TT4PQ%0~R0OXPRUHY7E&!4~W337J71V4WDDI6$GS9480XP0TNP2I$1YX75S
ZL0X~TT4PQ%0~R0OXPRUHY7E&!4~W337J71V4WDDI6$GS9480XP0TNP2I$1YX75S
string---string
Everything the way it's supposed to be....
What I don't get is, why isn't the if statement true? Shouldn't it show test as
well? Where is my mistake?
I run PHP 5.1.1 on Windows. On my Win PHP 5.0 this code works proper, but not
here ?!?
thx JanBro

Hi JanBro:
Quick guess: are the strings the same length? I've been bitten many
times by string comparisons that appear to be identical but which fail due
to trailing spaces, other "invisible" (i.e., non-printing) characters, and
the like.
Hope this helps.
Jon

Yep, they are of the same length.
here they are:
$SollKombination
ZL0X~TT4PQ%0~R0OXPRUHY7E&!4~W337J71V4WDDI6$GS9480XP0TNP2I$1YX75S
$formCheck
ZL0X~TT4PQ%0~R0OXPRUHY7E&!4~W337J71V4WDDI6$GS9480XP0TNP2I$1YX75S
When creating the string on the form page only visible characters were allowed.
thanks but that's not it.

Hey JanBro,
Try replacing the if statement you have with this:
if ( strcmp( trim($SollKombination), trim($formCheck) ) ) {
echo "test";
}

Hi Jeremy,
I tried if ( strcmp( trim($SollKombination), trim($formCheck) ) )
same negativ result. For some reason both strings are not considered to be the
same.
They have the same length, are of the same type and have the same content. Why
PHP
doesn't recognize them as beeing equal.... I don't get it.
thanks for your help so far

This is just a shot in the dark, but have you checked the HTML source of
your test to make sure that some of the characters aren't been parsed as
HTML entities? That would technically make the strings different, but
you wouldn't be able to tell with just echoing alone.

I would guess that the '&' in $_GET['formCheck'] will cause problems...
Trying your code without the ampersand as in:
$_GET['formCheck'] =
'ZL0X~TT4PQ%0~R0OXPRUHY7E!4~W337J71V4WDDI6$GS9480XP0TNP2I$1YX75S'
It works just fine.

PHP General List,
This is something I tried to find on Google, but I'm hindered by not
knowing the proper terminology.
On many sites that have contact or registration forms, they have a
small image file with a randomly generated number shown in a distorted
graphical fashion that is hard for a computer to scan and read.
The purpose is that the site visitor has to type in the numbers into a
field, in order to verify that it is, in fact, a human filling out the
form.
First, is there a term for these kinds of images, or that kind of
verification system? What would be the best search terms to look for
source scripts?
Second, can anyone recommend a resource for that kind of PHP script. If
I really worked at it, I could probably write the script to generate a
small PNG image with a random number in it. But I haven't the faintest
clue how to distort it so it's only legible to humans, nor how to
correlate the image with a number that a user inputs into a form field.
Any advice would be much appreciated.

Google for "CAPTCHA", and you'll be amazed at the number of hits!
