Submit Standalone Programs With Php
I'm building an application which submits scheduled php jobs. The way I would like it to work is to have one php program to submit the other php programs on a scheduled basis. This control program shouldn't have to wait until one job finishes before it can start the next one; instead, it should be able to submit all the jobs in one go, but it also needs to be able to be informed of the return codes of the submitted programs so dependent programs can be submitted too.
I've looked at the exec() and system() commands, but they either don't seem to allow return codes to be returned from a submitted program to the submitter program or they unconditionally print anything the submitted programs produce.

Standalone Problem
I've set up PHP 4 with Apache on an intel/Redhat 6.2 linux box with no network interface. Using URL PHP code with the .php extension works fine, but php code in html documents does nothing. In fact, view source shows the php code on the browser.

Multithreading For Standalone Php
I'm trying to write a mutlithreading server with standalone PHP. Concurrent requests is possible. Normally it is done by handling each socket spawn by serversocket in separate threads. But it seems that there is no thread support in PHP at all. Would anyone give me some suggestions? BTW, is the community considering add thread support to PHP in the future? What is the major difficulty to import an existing thread library (such as pthread library) into PHP

Standalone Program
I'm going to be doing a program for an elderly couple who owns a horse ranch, and wants some software to keep track of all their horses, owners, doctors, etc. I'm going to be writing the program in PHP using a MySQL database. I set up one like this for my work and it runs off of Apache on our server. I need this program to be a stand-alone install, without installing MySQL, PHP, and Apache seperately. How could I go about integrating it all into one package?

Standalone PHP Installation
I have never installed PHP before. It's always been set up for me. I have a client whose site is hosted as a virtual server. I'm trying to set up ecom for him, but the mhash library is not installed. So I use fopen to open a script on my website that hashes the variables. Obviously, this is not ideal because if my site goes down his ecom will too. I asked the tech people at his hosting company to set that up, but they said they don't do custom compilations. "As per compiling PHP with --with-mhash=[DIR] this is how that works: any custom compilations, custom applications, etc. are up to the user to compile and install. Use gcc/etc. to compile PHP with the options that you like. The php.ini in /etc is available for your customization as well. If you compile your own binary of PHP, you can place it where you like (or leave it at the default) and get the paths updated to use it, or you can obviously use it directly if necessary." I was planning on compiling a new, minimalist version of PHP (with just mhash) in a different directory, but I'm hesitant to do it in case I get unexpected results (I don't want to take the rest of his site down). Can anyone tell me if this sounds feasible? What kind of pitfalls can I expect? And can anyone recommend a tutorial? Most of the tutorials I've found assume you have root access and/or are compiling PHP/Apache together. I was also wondering if it would be possible to just compile the mhash library and add it to php.ini? That seems to be the simplest thing, though I don't know if it would work...

Standalone Solution
I was asked to write a database solution for a friend.. it was supposed to do the normal add/retrieve/modify/search functions of a databse. i started with vb6 then decided to use php/sql. I might sound really dumb and ignorant but the question is... if i want to "package" this to him... how can i do this without having to personally go and install a webserver and php and sql and the rest so he can use it just through his web browser? can i use an installer that will allow it to be packaged so after the install he would just have to open the databsae through his browser?

Standalone DB (like Access) For PHP/Apache
I am in the process of translating an WIndows/ASP/MsSQL Content Managment System (CMS) to Linux/PHP/???. Is there a popular database I can use that will allow standalone files like Access did (which used .MDB files)? In order for the CMS to work, there needs to be a standalone database file that is self-contained, just like Access .mdb files are under Windows. I guess I am asking for an Access equivalent for Linux/Apache.

Standalone Executable File
I downloaded the tarball and while was able to compile within PHP with no problems, I am having memory timeout issues involving image manipulation with extremely large images (800K - 2mb). Requirements are to create thumbnails for even these banner-sized images, but PHP + GD + [huge image] = too much memory. I'm trying to prove that it is undoable, though the suggestion was to do a command-line GD call to the image instead of using the PHP functions to do so to save some memory; if it still times out, then it's undoable altogether. However, I cannot find the standalone executable file that will ensure I can run GD from the command line.

PHP Calling Programs On AS/400
I have a website (running on a linux machine) that currently makes use of JSP to access data on an AS/400. I've found information telling me that after setting up ODBC drivers on the linux server I'll be able to access the databases on the AS/400 however I've not found any information about executing programs on the AS/400. I've looked at the docs for exec, passthru, etc. and it appears those will only work on the local operating system. Is it possible for a PHP page to execute a program on a remote machine? If so, how does PHP handle the ASCII <--> EBCDIC conversion for parameters passed and returned?

Test The Same Programs
I'm building my php scripts in one computer and i don't have any problem, but when I test the same programs in other (win xp ie) don't work at all, specially whe you do submit. I tried testing with this simple script: <?php if($_POST["test"]){ print "test ok"; print $testa; } ?> <HTML> <HEAD> </HEAD> <BODY> <form action="<?$_SERVER['PHP_SELF']?>" method="post" name="forma" enctype="multipart/form-data"> <input type="submit" name="test" value="submit"> <input type="text" name="texta" size="20"> </form> </BODY> </HTML> When you submit the form, print "test ok", but no the value of $testa variable. I use this way to send data and always works. (wamp5). I checked the services wampapache and wampmysqld and both are working then i tried printing phpinfo() and it works too.

External Programs
I have just installed my first Linux distribution (SUSE 10.0). Everything is compiled as far as Apache, Mysql & PHP is concerned. But, I have this problem: I call system commands through PHP using system, shell_exec etc The thing is that PHP responds OK when it comes to 'ls' or 'grep' or 'wget', but, in another program, not UNIX-native, there is no response. I am sure that the program is set up in the PATH, because, if I open a terminal, I can call it from everywhere and it works fine.

Executing Programs On A Server
i've written a c++ program that converts one file type to another via two arguments (the input and output filenames). i want to execute this on my server, using something like exec("myprogram.exe $arg1 $arg2"); but then I realized my server is linux, and my program was compiled for windows. so I uploaded the .cpp instead, and now i'm trying to compile it doing something like exec("gccp hello.cpp"); which returns an exit code 127... not really sure what that means. I'm guessing I probably don't have permission to be creating files on my server...is there anyway I can change this permissions or anything?

Multiple External Programs
I have a php script which when executed calls an external program. The external program goes off and figures some things out and the output of the program is returned as as an array to the calling PHP program. Next a second external program is called and the process is repeated. This goes on for 4 external program calls. The arrays are then analyzed and the results are outputted. Since the 4 external programs are independent of each other but each takes 3 5 minutes to run, I would like to run them all at the same time and then, when they are all done, proceed with the rest of the analysis.

ImageMagick And Executing External Programs
I have installed ImageMagick and GhostScript (Windows/IIS) and IM is working from the command line (specifically the convert command) so now I need to get it working in php. To that end I have the following code: <?php system("c:Program FilesImageMagick-6.3.4-Q16convert.exe c:InetpubwwwrootexpgraphicsimgMagick est_file.ai c:InetpubwwwrootexpgraphicsimgMagickAIC.png",$retvar); echo $retvar; // Now you can check the $retvar for errors ?> c:Program FilesImageMagick-6.3.4-Q16convert.exe - the root folder for IM, location of convert.exe c:InetpubwwwrootexpgraphicsimgMagick est_file.ai - the location of the target image to use for conversion c:InetpubwwwrootexpgraphicsimgMagickAIC.png - the location, name, and format for the converted image Using the above code, it does not create a new png image. Before I set the permissions for the Internet Guest Account user to "read & execute" for the cmd.exe file located at C:WINDOWSsystem32, $retvar was echoing a value of -1. Once I set the permissions on C:WINDOWSsystem32cmd.exe, $retvar is echoing a value of 1. In either case, the new graphic is NOT generated. Is there something wrong with my syntax?

Sparse - New Framework For MySQL Programs
I believe I posted this once before, but enough has changed that I'm doing it again. 8-) I have been working on a project called Sparse, a framework specifically for creating PHP/MySQL programs. It is designed with usability in mind - it is meant to be as easy to use as possible. Essentially, the majority of the backend is already done for you, and you can design and configure your website using a few extra HTML tags. It's also very flexible - you can easily integrate it with regular PHP code right in the file. The new version also prints out every form in degradable Ajax, meaning that those users without Javascript ability will use the regular functionality. The end result is far less code, meaning less development and maintenance time, fewer errors, and more ease in changing things around.

Executing External Programs From PHP4 On Windows98 With Apache 1.3.14 For Win32

From my understanding, the exec function in PHP seems to work best with Linux (correct me if I am wrong please!). Are there alternatives? The other bit of knowledge I have not been able to find (and really is outside this forum), is that dialer.exe is supposed to accept control from external programs, but I have yet to find docs or examples of such.

Bypassing "submit" Or Auto Submit With Forms Data
In a regular HTML screen where you have inputs within a FORM, you usually have a SUBMIT input tag to submit the form data to the action'ed item in the form tag. In alot of sites, I see that you can enter a field, then to its immediate right, is a GO button to submit the choice. Has anyone had experience with this, and if so, how would you code that in PHP? I have also seen where you can choose something from a dialog box, and as soon as its chosen, the form data is submitted. Is that possible in PHP also?
