Re: [PHP] accessing data from classes
It is good that you are looking into classes and functions. The concept
you are missing is that of returning a result.
At the end of your function mysql_query, add a line:
return $result;
Then, when you call that function, make it like this:
$resultArray = $TemplateTable-mysql_query(select );
Now you can pass $resultArray on to a different function.

I am just getting my head around classes, so forgive me if this is a
schoolboy error!
In order to learn I am re-writing my content management system and am in the
process of writing an HTML.class and a MYSQL.class.
so far so good. I spawn new instances of a table for example, sending
parameter,and a table is output.
now in my MYSQL.class- I want to send a query to my class which then returns
an array- my database row or rows.
the problem is that whilst my array is created- I only seem to be able to
manipulate it within my MYSQL class. This is not satisfactory as I really
want to be able to send it on to my HTML.class for formatting etc.
I obvioulsy do not want to format any 'echoed' output from within my
databasee class.
Here is a bit of sample code-
Once my database is open I call my query like this-
$TemplateTable = new DB;
$TemplateTable-mysql_query('SELECT * FROM template ORDER BY name ASC LIMIT
10');
This is the function within my MYSQL.class
function mysql_query($query){
$a= 0;
while($row=mysql_fetch_row($SQL)) {
$new_row = join('***',$row);
$result[] = $new_row;
echo $result[$a].br;
$a++;
}
}
So here I am creating a string with each row in my database which is
delimted by *** - $new_row.and am placing each row in anew array called
$result.
I can evaluate and format either $new_row or $result from within
mysql_query() but I really want to do is to send it on to another funtion or
even better another class- or access the values glabbally as variables.
Any ideas or am I missing something really obvious?
Thanks in advance

Re: [PHP] attachment through mail
There is a very good article (with some well written OO classes) available at PHPBuilder. http://www.phpbuilder.com/columns/kartic2807.php3 I think the classes are at: http://www.phpbuilder.com/columns/kartic2807.zip This will make file attachments very easy. BTW, the PHPBuilder columns section should be bookmarked by most people.

Re: [PHP] connection speed?
There aren't too many elegant ways to do this, that I know of. You can create a flash movie with a big chunk of nothing in it... With a couple of calls, you can find how long it took to load So if it took 4 secs to load 200k You can sort of figure out their connection speed. But unfortunately, there is not going to be any: $speed = get_connection_speed(); Sam On 3/11/02 2:29 AM, Kunal Jhunjhunwala [EMAIL PROTECTED] wrote: Hey, How can I detect the users connection speed?

Re: [PHP] Update database via email
If I were you, I would start looking into procmail. http://www.procmail.org You would set up an alias on your server... Something like [EMAIL PROTECTED] Procmail would filter the email for the important stuff and pass that on to a PHP script. The php script would then update your database. Try a google search on procmail php.

Re: [PHP] Image upload and scaling
Someone just mentioned ImageMagick... Check it out: http://www.imagemagick.org/ ImageMagickTM is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats (over 68 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image and save your completed work in the same or differing image format. Image processing operations are available from the command line, as well as through C, C++, Perl, or Java programming interfaces. Or you can check out the built in gd functions. http://www.php.net/manual/en/ref.image.php Sam On 3/11/02 12:21 PM, P.Agenbag [EMAIL PROTECTED] wrote: Hi, I am trying to make a util whereby ppl can upload their own images to my server for me to automatically display them.

Re: [PHP] limiting the livetime of a session possible?
The last person gave you a way to do it without using php.ini Re-read the reply. 1) you can create a timestamp column last_access in your USERS table 2) every time that user hits a page, you need to update that column 3) every time the user asks for a new page, see if the last access is less than 60 minutes. If not Session_destroy() Send them to the home page. Sam On 3/11/02 1:14 PM, Andy [EMAIL PROTECTED] wrote: Hi Andrey, is there no way to control the lifetime without modifiying the php.ini?

If PHP4 there is an option in php.ini to set about how frequently the GC(garbage collector) will be started. Otherwise if self made and using a DB for backend - add new field last_time , and on every page request do Delete from session_table where last_timenow() interval 60 min; not sure for the query but that is the idea.

Re: [PHP] Broadcasting
This is sort of a weird question as it seemingly involves both physical theft and virtual theft. But here goes: 1) How do script kiddies find you? If you have a public IP address, and you are not protected behind a firewall, you will be probed by scripts. How do they find you? By port scanning large ranges of IP addresses. They often scan all the RoadRunner ips... So they start in 24.x.x.1 range and work through all of them testing out common ports (http, ftp, ssh, etc). Then, if the script finds an open port, it will test out an exploit (or a series of known exploits). For example, FTP usually runs on port 21 If the script finds an open port 21, on a RedHat 6.0 box, it may try the remote root exploit of the ftp daemon (wuftpd). If that doesn't work, it just moves onto the next one. If you are running a private apache server, and you don't want the public to see it, then it is time to learn about firewalls. 2) broadcasting your ip Your questions are odd here But yes, you can often learn a fair bit about an IP. Do a reverse dns lookup on a university campus and you can often find a lot Maybe seat13.mathlab.university.edu. Also, you can find out a lot from what Apache sends in the headers... Example: Apache/1.3.0 (Unix) PHP/3.0 MyMod/1.2 So, if I check out your server, and see that you are running PHP 4.06 on linux or solaris, a hacker could try the multipart/form-data exploit with a broken boundary check (http://security.e-matters.de/advisories/012002.html). There is a setting in Apache to limit this information in the headers so that you do not reveal what kind of OS you are running and what version of PHP and Apache you are running... I suppose this could help in limiting exploits. Although, keeping up-to-date with versions, patches, and security alerts is a better solution. http://httpd.apache.org/docs/mod/core.html#servertokens Sam On 3/10/02 9:45 PM, jtjohnston [EMAIL PROTECTED] wrote: Not really a php thing, more a loss of php :) !

My question is: does my Apache server broadcast itself or its IP for when script kiddies come check out my machine to see if they can crash it? What does it broadcast? How did the script kiddies find me? Can I reverse process this and see if my stolen machine still exists anywhere? What would I look for?

Re: [PHP] PHP based search engine
Check out phpdig: http://phpdig.toiletoine.net/ My guess is that one of these packages on the web can serve as a foundation for you... You might just need to build a custom layer on top of it.
