Re: [PHP] trying to figure out the best/efficient way to tell whoisloggedinto a site..
bruce wrote: ben... i understand what you've stated, but i was under the impression that a number of sites (etrade, etc...) can/do track who is/is not logged into their sites.. and not just by some crude 'timeout' function... Yes they do, the key there being that they are tracking who is logged into their site. You log in, they make a note of it, you log out, they make a note of it. If you don't log out and yet are inactive for a period of time your login becomes stale and you are logged out automatically by the timeout. i might be wrong, but it was my understanding that those kinds of sites have the ability to more or less know when someone kills the browser session, and is no longer on the system. these kinds of sites also ustilize some form of a 'timeout' process as well for users who simply have browser sessions that are inactive... by your statements, you're pretty much saying that the only approach one has to this issue is to utilize some sort of timeout function, and if you don't detect user activity after your timeout, then mark the user as no longer being active, and proceed accordingly. this apporach doesn't allow an app to immediately know when a user has killed the browser. so, the question might be, how does one detect when a user has killed a session/left your app? Provide a login/logout ability and when they log out you kill their session. This is how an e-trade like site would deal with it. If they don't log out you still won't know they have left your site until their session times out though. Some reading on HTTP would help you understand why what you are looking for is not possible. - Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

bruce wrote: ben... your statements/approach is pretty much what i've been thinking of. however, with regards to the forums/cms apps.. i've yet to find one that actually keeps a track of the logged in users, that works when the user kills the browser.. the ones that i've seen, that allow an admin to see who's online, appear to fail when i've killed the test user. the apps still show the killed user as being online... hence my isuue! Bruce, what I have been trying to explain is that this _can_not_ be overcome. The web is stateless. Connections between server and client last only long enough for a file to be requested and sent, once that has happened the server and client are no longer connected and have no knowledge of each other. _No_ server-side program will be able to tell you when a user closes their browser or goes to another web site. HTTP simply doesn't provide what you are looking for. - Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: unbale to send mails using mail function
Have a look at the path to sendmail in your php.ini file. To get mine to work I had to set it to '/usr/sbin/sendmail -t -i'. Your path may be different, but the -t and -i switches are important. - Ben Sanjay wrote: > Hi > > I have successfully installed PHP 4.0.6 with apache 1.3.22 on my mandrake > Linux box.

[PHP] PDFLib - Builds & Installs, but doesn't show up in phpinfo()
Hi all, I've been banging my head against the wall for a few days and have finally decided to consult the list. Here's what I'm trying to do and what is happening: Platform: Various version of RH Linux, primary 6.2 (on an i586), but when that failed (repeatedly) I started trying it on a 7.1 box (Athlon). Goal: Build libpdf support into PHP for dynamic pdf generation What is Happening: -libpdf appears to configure, build, and install properly (from source) -php is rebuilt and appears to configure, build, and install properly -the output of phpinfo() does _not_ list any information on libpdf and libpdf functions do not work What I've Been Doing: Aside from beating my head against the wall I have been configuring libpdf builds with the following: ./configure --enable-shared-pdflib --enable-php --enable-cxx The output at the end of the ./configure process indicates that shared library, C++, and PHP support (among others) has been enabled. pdflib then appears to build and install properly with 'make; make install' * Note, I have been blowing away the pdflib source directory and re-untaring each time I do a build. For PHP builds I have been configuring with the following: ./configure --with-apxs --with-pdflib=/usr/local/lib --with-mysql=/usr/local/mysql/lib/mysql --with-zlib=/usr/include --with-ttf=/usr/lib --with-jpeg-dir=/usr/lib --with-tiff-dir=/usr/lib Again, it appears to configure properly. I then build PHP with ./make and ./make install. When apache is restarted and the output of testinfo() is checked pdflib is _not_ listed and pdflib specific functions do _not_ work. The configure options shown above are listed in the Configure Command portion of the output. Any pointers or tips would be most appreciated. I would be happy to provide any additional information that might explain what I've done.

Assuming it is (and I have my doubts), if someone comes to your site with a browser window width higher or lower than 800 the browser will have to chose between your width setting and your margin settings. One of them will have to take priority because you can't have a width of 800 and a margin of 0 if the viewer's browser window is 1200 px wide... or 640 or any size other than 800 for that matter. - Ben -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

using 'include("secondfile.php");' should do the trick. The second
script is, for all intents and purposes, essentially inserted into your
first script at the point of the 'include' statement. There is no need
to pass variables, although the usual global/local variables issues
still apply with regard to functions (ie drop the ?var= stuff).
If you continue to get "Failed opening" type error messages check the
read and execute permissions on the second script. Can the second
script be run directly via a browser? Is the path to the second script
used in your include statement correct?
