I only need the session to pass the url on to the next page ... once there
the old URL will be written into the HTML code... The only reasons I need
to do it with sessions is because my urls are too long for the encoded url
to be transfered reliably within the url...
>2. I do this sort of stuff by building my own URL from $_SERVER components:
I haven't found the server array in the manual (yet anyway), so I'm not

I don't have that problem. Variables aren't reausable because I'm doing
divide and conquer design ... that way I can prevent the code from being
too complex and requiring to many variables to work. Thus my variables
differ from master page to master page, all the common ones are rewritten
on each page load (as it only controls the menu links to be linked
correctly up/down folder levels).

Apparently the trans_sid being on (or 1 as it is) makes the sid transfer
correctly everytime, atleast with my current setup ... which is this:
On mother:
$_SESSION['mother'] = "girlz.php?locat=$loc&list=$list&year=$year";
On child:
if ($name != "") {
$backlink = "<div align=\"center\"><a
href=\"".$_SESSION['mother']."\" class=\"bldlink\" title=\"Get back to
where you came from\">Back to where you came from</a></div><br />";
echo($backlink);
}
And before you ask, the reason the backlink is in a variable is because
it's reused a couple times down the page.
The above is, of course, only part of the code. It checks for alot more
stuff in the child file. Still have to work out how to ensure that the
backlink will produce a workable return link even when the page is
launched without a call from a mother page...
But that'll have to wait until morning ... it's 4.45 AM here now ;-) ...
gotta get some snooze...

John has shown a tremendous willingness to help people on this list - and I can undertsand him getting frustrated by the number of unclear questions...
I sometimes read this list and see if there is anything I can give back to the community ...
..but often give up trying to find questions I can answer in amongst the cryptic posts some people seem to think are a way of asking for help.
I think the bandwidth wasters are those who ask questions poorly (it takes several follow up mails to find out what the question was) and those who don't have a qucik look at the archives first (is someone puuting together an FAQ ?)

and ot.ip = whatever you need to get the right record.
The above is untested and you may need to modify it to suit your database's syntax (you do not tell us which), but it should give you the general idea.
Sean, the difficulty is that you were not explaining what you wanted clearly enough, not giving us enough information. It took several posts to do that. John's simple answer "yes" was a humourous hint to that. All we knew is the few lines of your original post, we don't know if you are ace programmer and database wizard or newbie. You know what you want to achieve and the backgroud to it, we do not. You know your response was out of line. I think a simple apology would be appreciated. John is a mainstay of this list and deals with many requests for help per day. Its a high volume list, please stay on it yourself and find out. See if you can help others.
Its also php-general so should really be for requests that do not fall into other catagories such as php-db, php-install or mysql, its not a database list. I feel that many people post to this list, even with off-topic questions, because they know they will receive help. Why? Simply because there are people such as John who wade through hundreds of posts every day, putting themselves out, and doing their best.

--- Begin Message ---If you're on a dedicated server (no other sites on the server), you could just count the session files in /tmp. Otherwise, the general consensus seems to be that you need to decide how long a user is "active" for (say a minute, or 3, or an hour?), and save (eg) the SID and timestamp in a file or MySQL table. In theory, you then count the number of sessions that were created or reactivated (restamped) within your definition of "active" time (eg 3 mins). This has been discussed waaay too many time on the list... do a search on the archives for 'active users', perhaps also try a search with the word "ASP" too :) Justin on 19/01/03 10:27 PM, Jeremías Grunge ([EMAIL PROTECTED]) wrote: > Sorry I'm novice. > > There is a way to know how many sessions are active and to get variables or > the id of them? > > Thanks > >--- End Message ---

My impression was that the affects of GPL requiring software developed from the original GPL to also be free was only applicable to modifications of the program itself.The GPL is a ridiculously outdated and vague license which has rarely been tested in any courts (if ever) and therefore there's no clearly established caselaw to base decision on. 'outdated'? 'vague'? GPL speaks of 'linking'. How is this to be defined? The GPL has language (linking, binary, compiler, kernel, etc) which is not something which even enters into the consideration of most developers who use scripting langauges (perl, php, python, etc). The GPL was written almost exclusively with C and similar languages in mind, although it's not explicitly stated anywhere. "derivative works" is not clearly defined. If I distribute a PHP script, is calling a 'wordwrap' function somehow 'linking' to the original PHP code? My program's functionality certainly depends on the wordwrap code functioning properly. Is it a 'work based on the Program'? The definition states that 'a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language.' Whose copyright law? The original developer's? The 2nd generation developer's? Translated into another language is damn vague, imo. If I take the original wordwrap function code - in C - and translate that to Python, have I translated it to another language? I realize that the PHP code isn't GPL - I'm not speaking specifically to PHP, but to the GPL 'definition' of things. It's a shame so many people just write stuff and put it out under GPL without coming close to understanding the implications of the license, or the ambiguities. At some point, there will be larger legal cases which will invalidate some of the principles which developers though the GPL meant, but didn't really understand.So if php was
GPL and I modified the source and built my own customized version of php I
couldn't sell it but could only give it away,You can sell GPL software. Often there's not much point because you have to grant the right of redistribution to others, so the first person you sold it to would be able to redistribute the source code (because they're entitled to recieve the original source code), thereby being able to undermine your sales efforts. In practice, many people probably wouldn't bother redistributing something, but it would only take one person to do so to have the impact. Also, just because something is GPL doesn't require the original developers to give it away to everyone by setting up FTP servers and all that other stuff. All you're required to do is provide to source to someone who requests it, and you only have to do that if they got it from you. Example: I have a large system which I GPL. I distribute a binary to customers who purchase it. My only obligation is to provide source code to the customer upon request. At that point, THEY can recreate a binary from my source and sell that, but they would also then have to fulfill requests for the source (which they may not want to do). *I* do not have to fulfill requests for the source to anyone except those to whom I distribute/sell a binary version. That's really it. but if I used php to developsome other software that runs on php I could sell it without a problem.
Similar to creating software that runs on Linux, the software can be sold
but if I modify Linux itself and turn around and sell it, it would be
against the license.Again, no, you can sell it, but you're obligated to provide the source to any purchser who requests it, and you can't then stop them from redistributing it. Any Linux kernel changes you made then 'sold' would either not sell at all, or would sell a couple copies then get rolled back in to the main tree of some distribution.

Subject: [PHP] Changing order of just one array item?
I need to change where one item is ordered in an array. I know how to sory an array, but I need to move one item up/down in the array. Example: $array is: 0 => "element one" 1 => "element two" 2 => "element three" 3 => "element four" I call array_order_up($array[1]) and $array is now: 0 => "element one" 2 => "element three" 1 => "element two" 3 => "element four"
If there aren't any native functions to do this, can anyone think of a way to make my own function to do this?
