I generally do the same basic thing for permission levels, but a
reverse of what you're attempting to do.

The superuser (AKA root, administrator, God, whatever) has GID 0,
just like on a *NIX system. This is because it's the highest level
you can reach, and 0 is the lowest real number you can use. Thus, you
can add a virtually-infinite number of lesser users, as opposed to
being limited to 50, as in your case.

Sounds like a pretty typical setup.

Depending on your layout, you may be able to use a templating type system for
the pages as well. It's hard to tell if that's useful without more
information.

/tmpl/<companyid>/index.php

Not sure if that's what you meant by using the company name or if you were
going to do something like "company30" "company50" and such.

Lots of different ways to do what you're talking about, but sounds like
you're in the right path.

Hey TG,

I was thinking about doing it as "CompanyA" "CompanyB" etc... etc...
All stored in a database. And they can all go to the same main website
and be able to get at everything they need.

Thanks for looking! :)

Which makes sense for when my KeWl ApP goes public and gets l33t
status! :)

That's what we all hope for though right? :)

Yeah, but then if you try to add a super-superuser you have to go negative. :-)

Why not just define the users with define CONSTANT statement and use
that? Then the different types of users can be anything you want and
you can change the value easily if there's a problem.

Really, all the value really has to be is unique -- you could use
unique() for that, such as:

define("ADMIN", md5(uniqid(rand(), true)););
define("GENERAL_USER", md5(uniqid(rand(), true)););
define("LEVEL_ONE__USER", md5(uniqid(rand(), true)););
define("LEVEL_TWO__USER", md5(uniqid(rand(), true)););
define("WHATEVER__USER", md5(uniqid(rand(), true)););

and so on. That would work and you'll never have to be concerned
about it nor worry about someone guessing it, if that becomes a
problem.

Am I right?

In actuality, there would be no such thing. However, for
posterity, negatives will work. So long as:
<? if($_SESSION['userlevel'] < $group_level) { ?>

.... evaluates to true. ;-P

I don't think I could handle two. So if AGNES won't beat me
nightly with a sack of oranges ("because it doesn't leave bruises, but
it gets the point across"), Debs is going to come home and find her
stuff in a box.

I think the chances are very remote. You probably have a better
chance of winning the lottery ten times in a row.

On the other hand, if you assign the number yourself, your chances of
making a mistake is far greater.

But, now that I think about it -- you don't need a number at all, you
could use:

define("WHATEVER_USER","WHATEVER_USER");

The value portion in the define statement can be a string -- so cut
to the chase and make it as difficult on yourself as you want.

Cheers,

tedd

I sometimes set stuff up like this:

user
userId

user_permission
userId permissionId

permission
permissionId sort

Then the level of said permission is based on the rank "sort" value.
That way if you want to add a super super user, just change that
value.

But I also map these to constants like you said too. Using all those
unique id calls is going to really be slow FWIW. Every permission
system is fairly unique in the apps I program though so nothing is
really set in stone.

Read up on "ACL's."

http://en.wikipedia.org/wiki/Access_control_list
http://framework.zend.com/manual/en/zend.acl.html

attached mail follows:

Wait, what?

You are defining user role ids as MD5 hashes of UUIDs created from
random numbers that change on every request?

Am I missing something or is this completely insane advice?

Apart from Zend which you've mentiond below, is there anything in/for
PHP that will help implement ACLs for a PHP application?

Does anyone use the Zend ACL stuff?

No offense meant, but if you're concerned about the "if" overhead
then I question if you would understand how the double menu works.

A PHP session destroys itself as soon as the client disconnects from the
site.

Why if I connect from another machine, log in, and disconnect without
logging off, and return 5 mins later, my session is still alive ?

    A session only expires in three cases:
        a.) An explicit session_destroy() is sent.*
        b.) The user-side cookie with the session key expires.
        c.) The session corrupts.+

* You can also unset() or session_unset() all of the $_SESSION
variables, but it still won't kill the user's cookie.

+ The session won't always automatically be destroyed in this
case, so don't rely on it.

I didn't set any cookie so it must be the php session cookie.
How can I check for the visitor's presence ?
I can't set a timer or check for activity since the visitor can be studying
an online document.
I must rely on the browser connection.

It can build a lot of stress on the server.

What if I use connection_aborted() ?
In the status line of the page I can write a 'connected' timer and use it to
check the connection !?

At most I'll have a 30 secs. time lapse. (30 secs. is the default execution
time for scripts)

What do you think of that?

Thanks

That could work for very short sessions, sure. This was for a
larger, longer, community-style script. And it wouldn't cause very
much stress on the server, actually, but with large communities of
655,350+ (using a Magic Number[tm]), you
surely wouldn't want the cron to run every 10 minutes.

The example from the link is set to see if a user is still active
on the site. If all you want to do is find out if they still have the
socket open, then there are much smaller, simpler ways.

you can easily set up an nfs share on one of the systems, and have the other

this would allow a box to write to the share, with the other boxes being

Thank you all so much for replying... I guess I was very vague in
describing the situation. I will write in detail:

I have three computers A, B and C. To login to B and C I should use A
because it has a SSH key. I don't have any other way of accessing these
two computers. Now, if I need to transfer a file between B and C, I am
unable to find a way that would work... because I don't know how to
authenticate without SSH keys... I was gathering some data in B and C
using PHP. Now, I need these two computers to coordinate a little and
didn't want to use a server in between and so I was thinking of
establishing a direct connection between them..

I have about 10 csv files I need to open to access data. It takes a lot

If you can't store the values in a real DB, then that might be an option.
You might consider using a temporary table if it's available in the
database you're using, that way you don't have to worry about implicitly
creating then destroying the table.

The only problem is how temporary the temporary table may be. If you can do
everything you need in one connection, then you should be good. Otherwise
you'd want to use either a persistant connection or use a real table.

You may also load all your CSV data into an array, but that may use up more
memory and be slower and/or more cumbersome to search.

You could try out a few scenarios and see how they work speed-wise and impact
on system memory and such.

Dan,

I can tell you that depending on the size of your files is going to
dictate the route you want to go. I have a CSV with 568,000+ lines with
19 different pieces to each line. The files are around 180M apiece and
it takes my server about 2 seconds to run a system grep against the
files. I can run a recursive call 7 times against a MySQL database with
the same information and it takes it about 4 seconds.

IF you have system call ability, a grep wouldn't be bad, otherwise I'd
suggest loading the csv files into MySQL tables and checking them for
the information, then dropping the tables when you get the next files.
You can backup the databases such as a cron job overnight even.

HTH,
Wolf

Thanks that sounds like a good idea. I'm still plugging away with how I
started. I want to know how much faster it will be going with a db. I
was actually thinking of using diff for each updated file to and upload
that to the DB.

Running a diff and loading the changes wouldn't be a bad way to go, one
thing to take into account as well would be any tracking of the changes
that you would need to do as well. IE, if you update an entry, write it
to a changes table with a date attached as to when it happened.

While that could work if the server is set up to allow you to run system
calls, but you don't find that available outside of test environments.
Also depending on the file sizes, you'll see some differences.

Hey Rob,

Remember on 2007-09-18 at 22:45:37 when you suggested I do this:

http://marc.info/?l=php-general&m=119015558426248&w=2

Well.. today strtotime( 'last Sunday' ) screwed me and I'm writing to
say that I nearly fell out of my chair laughing when I realized what
the problem was, who caused it, and who "helped" me code it. :)

This issue only appears on an ancient PHP4 install as far as I can tell:

echo "Current time():\n";
echo date( 'Y-m-d H:i:s', time() );
echo "\nBroken strtotime( 'last Sunday' )\n";
echo date( 'Y-m-d H:i:s', strtotime( 'last Sunday' ) );
echo "\n";

> /usr/local/php4/bin/php test.php
Current time():
2008-03-10 20:03:39
Broken strtotime( 'last Sunday' )
2008-03-08 23:00:00

23:00? Guess what we did to out clocks this past weekend?

I blame the republicans in general, and the short one named 'W' specifically.

I won't bother mentioning the fix as I'm sure 83,293,874,713 people
will post the same correct code by the end of the day tomorrow. No
one runs PHP4 except _my_ clients anyway. *shrug*

Watch throwing that blame around there Greg, you get to thank the
