Two Sessions: Session A By A Program Destroys Session B By A Program
I have two separate programs that I want to use together on a website
Program A starts first and calls session_start(). Program B is started by the user clicking on a link and it also calls session_start(). The session started by program B blows away the session started by program...

Php Session Problems When Working With A Windows Client Program
I am currently involved in a project that involves a windows client program written in delphi and a web application written in php. I have made several php pages for the delphi program to do requests via the http component from INDY. the problems I am having are: 1) the first request from delphi app to php web app is the authenication. In which user sends username + password to the php app. If authenication is valid, a session is started and the sid is returned to the client. All subsequent requests from delphi app to php web app will have this sid as one of the arguments in the POST form request (this is one of the function in the INDY component for delphi). Even the sid is passed to the subsequent pages, the session global array is still undefined. However if I open up a web browser and create my own string request to the login page then the next page, the global array would be defined (using var_dump + echo to see the array) what is the problem? 2) does the above problem has anything to do with the http referer field? 3) this problem that I am having has been asked before on google group, but somehow the person who asked it didnt' put down the solution for it. (this only involves the web only) when I login on a page and return with a session id, then I log out.. the user is redirected to the login page again. However if the user login again (with a different login account), he would be presented with the same session ID as before. a different sesson id is presented only if the user restart the browser. why is that happening?

Session Destroys Only A Page Later?
This is the code that I'm using to check if someone is logged in or not. This code is on every page because there is a login or logout button on every page. if (!isset($_SESSION['user'])){ echo '<a href="login.php">LOGIN</a>'; }else{ echo '<a href="logout.php">LOGOUT</a>'; } In the flow of my php document this checking if the user is logged in happens after the actual login or logout script. Because of this, I assumed that as soon as someone logs in, the code would reflect the change. For some reason, on the page that logs me in, the code still thinks that the session is not set yet and therefore I still see the login option. Same thing with logout. It takes for me to click on another page for the code to finally change. Any ideas what is going on?

Refreshing Or Navigation Away Destroys The User Session
I searched the forums and after a day and a half of researching I need your help. I'm having weird session issues on my testing environment. I have a login that stores a 'User' object in a session. Once a user is logged in, they're redirected. For testing purposes I outputted the session ( print_r($_SESSION); ) into the footer so it's viewable from all pages. After the redirect from the login page any refreshing or navigation away destroys the user session. Code:

Sessions? External Program / External Program
I am trying ac ouple of days now to learn some things on SESSIONS,but I think I am not getting it very clearly. I have a PHP page tha contains a form. Users enter data in the form, which are then written in a file (the file is created at the time a user enters some data) The file is then given as an input to an external program The external program runs and gives some results which are then stored in another file (that is created when the external program finishes) What I want to do is to somehow create these files and, when the user exits from the browser, then both files that refer to this user, will be deleted.

Session Problem: Session Exists, But Session Variables Don't Lasts
I have some troubles with session variables. I can easily create a session, but the variable I append to global session array ( $_SESSION) lasts only until the end of current function. I prepared an example that can demonstrate the problem (see code bellow): The program flow is this: (1) It starts with "session_start()" and displays "login_form()". (2) When user enters his username and password, it goes to "login()" function which sets $_SESSION variables. (3) This function also "Echoes" session_id and user name to the screen. (4) Then it goes to "MyProgram()" function. It only "Echoes" the same variables to the screen. Strange is, that the session_id is the same in (3) and (4), but the user name ($_SESSION["username"]) is only in (3), but not in (4). By other words - $_SESSION["username"] variable filled up by "login()" function is immediately cleared. I don't know why. There must be something missing, but after 3 days of watching it, I can not find a problem here. =========================================== <? Function login($uzivatel, $heslo) { $_SESSION["username"] = $uzivatel; $_SESSION["pass"] = $heslo; $U_Name=$_SESSION['username']; echo "Login username: $U_Name<BR>"; echo "Login session ID: "; echo session_id(); echo "<BR>"; } Function login_form() { echo ("<DIV ALIGN='center'> <H1>Test</H1> <P>Please enter your username and password:</P> <form action='test.php' method='get'> <INPUT TYPE='HIDDEN' NAME='login' VALUE=TRUE> <TABLE BORDER=Ɔ'> <TR> <TD ALIGN='right'><U>U</U>ser name:</TD> <TD><INPUT NAME='uzivatel' SIZE=25 ACCESSKEY='U' TYPE='TEXT'></TD> </TR> <TR> <TD align='right'><U>P</U>assword:</TD> <TD><INPUT NAME='heslo' SIZE=25 ACCESSKEY='P' TYPE='PASSWORD'></TD> </TR> <TR> <TD COLSPAN=2 ALIGN='RIGHT'><INPUT NAME='OK' ACCESSKEY='O' TYPE='SUBMIT' VALUE='OK' TABINDEX=3></TD> </TR> </TABLE> </FORM></DIV></HTML>"); } Function MyProgram() { $U_Name=$_SESSION['username']; echo "Program username: $U_Name<BR>"; echo "Program session ID: "; echo session_id(); echo "<BR>"; } { session_start(); if ($_SESSION['username']): MyProgram(); else: { if (!$login): login_form(0); else: login($uzivatel, $heslo); MyProgram(); endif; } endif; } ?> ===========================================

Sessions - Two With Same Session ID As The Same Time
I just had a brainwave. I leave a session cookie on someone's machine so that I recognise them (with their session ID in the cookie) when they come back, I also offer them the option to have an email sent to their email address with a link that sets the session ID to the one in the emailed link so that they can open their account from another computer. Now, my question is, can you have two users on different computers be on the website at the same time with the same session ID?

Sessions Timing Out Even Though Session.cookie_lifetime Is 0
I'm running two version of php, 4.3.1 on my development box and 4.2.2 within production. What's strange is that for some reason, my session is being cleared after a specified time period. It looks like half an hour or so. So looking at php.net, I see the following: session.gc_maxlifetime integer session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up. session.cookie_lifetime integer session.cookie_lifetime specifies the lifetime of the cookie in seconds which is sent to the browser. The value 0 means "until the browser is closed." Defaults to 0.See also session_get_cookie_params() and session_set_cookie_params(). To me, session.gc_maxlifetime simply indicates when files will be cleaned up after a session is finished. My understanding is that session.cookie_lifetime determines when a session times out. As I'm writing this, I was performing a test. I simply logged in, identified which session file was mine (in the /tmp directory) and watched it. In this case, it looks like it took about 35 minutes, but sure enough, the session file was erased. Again, this doesn't happen on my dev machine, the code base is the same and to confirm that somehow my code wasn't the culprit, I just logged in and did nothing!

C Program And PHP
I have written this function in a C program, using Visual Studio. The PHP script executes fine, but the output is not displayed. I have been racking my brains for hours trying to figure this one out. The output from the php program should print to a file called 'out.txt'. The file is successfully created, but with no content. I am pretty sure it's the way PHP returns the results. Does anyone have any ideas? Any help would be most appreciated. int passCode(void) { FILE *phpFile, *out; size_t len; char buffer[1000]; phpFile = popen("php -f testing1.php", "r"); if (phpFile) { out = fopen("out.txt", "w"); len = fread(buffer, 1, sizeof(buffer), phpFile); fprintf(out, buffer); fclose(out); pclose(phpFile); return 1; } else { return 0; } }

How To Program OOP
I use OOP for a PHP Application Framework I am programming. I have one base class which includes all the necessary functions and variables which all the other classes use. So what I originally did was that I made an instance of the base class and passed it to the other classes. Now someone insisted that this is not the way to do it. so I used 'extends base' to make the base class available to the other classes. Afterwards it worked fine, but it didn't make the code smaller nor did it result in faster speed. I used the benchmarking script from PEAR. So I wonder whats the difference between those two solutions, both work fine. Are there some tools to analyse how much memory a script uses?

Run Program Automatically
I want to create the option for my clients to create their own e-mail address. When I do this in Telnet, I have to run the command 'vadduser' It then asks me for a username, I want to assign this automatically. (1,2,3,4 etc etc) It then asks me for a password, I want this to be something the user has already given in a form (before the script was run). It then has to be retyped. Those two things can be done automatically. It then asks if I want to assign a disk quota (YES) and then asks for the number of megabytes (1) That's it. Are there any examples available of how to do this?

Should I Use A One Php Program Or Multiple
I have taken over a php web site. Once you login you are given six menu choices. Each option is or can be independant of the others. They each modify the same database but in different ways. On clicking the menu buttons the program calls php functions to do the action. Thus the user stays inside a large program. I was expecting the menu to provide links rather than function calls. 1) Is there a reason to stay inside a large program through function calls rather than linking to separate pages? 2) Am I correct that providing a <a href=... link would isolate the functionality and call a new program? The current program is spagettii code and somewhat buggy. There are side effects that depend on what function was called before. I am hoping that passing the hidden input parameters is all the connectivity I need.

Survey Program -
I want to migrate a survey program to web application and have selected PHP to use a on the server end along with apache and firebird rdms. As developing a web application is much different than a standard app I have some questions: 1) The survey has 50 questions with answers being 1-10. Is it best to store all 50 questions and corresponding answers in a javascript array and then up all in a batch update? The downside to this approach is the user could lose all responses to survey questions if the client computer web browser crashed. 2) After authenticating the user, how do I keep track of the rating session to guard it from hacking? Do I just store the username in a javascript variable since there is really no constant connection to the server?

Program Flow
I had some bad experience with code organization and script functionality in writing my php based applications. And as the applications get bigger in scale it gets even worse. Therefore, I am trying to build a general schema for data flow in a php/mysql application. What I has in mind is to design a three major units. To handle the input, processing and data access. Plus another unit to generate the output. What I have now is one script that resolves the operation to be done according to the parameters send to it and the call the processing unit to do the rest of the job. However, as I add more functionality to the system this dispatcher script gets bigger and bigger... 1. How can I arrange my program/data flow in an efficient and easily maintainable way? 2. And how should I implement the output generation unit to be completely seperate from the others (I have lots of forms and outputs I have to show the user when necessary)?
