Re: Calling an executable for processing some data sent from PHP

Wow, thanks for the code and the fast response! :) Although maybe I should clarify my probem a bit more, I'm trying to run a program, but I want it to stay open so that I can call functions later. When the user "opens" a file, it's uploaded to a folder where PHP can access it, then PHP would call the Pascal program which would parse the file, and create a new object for that data, which later functions would access and do computation on. Like a user woud click Compute Subsets and that would somehow trigger the function Compute_Subsets on that object. Any way I could do something like this? My ugly way to do it would be to do an exec() to call an executable to parse the file and make an object of it then run the function that I needed to every time a function was called. The code base for this would be horrible to maintain and incredibly slow. Is there some way I could keep the program open and give it further arguments?

Will that script also work on Apache in Windows? OS X? Just checking because the backend and front end both need to be able to be installed on any OS. Also I looked at exec(), system(), and passthru(); they all let you execute a executable file but I don't see any way of passing parameters in any of those functions, can you do that? - Daniel ""Daniel Brown"" <parasane@gmail.com> wrote in message news:ab5568160706151311m3327bbccha02e3f5ca96255d8@mail.gmail.com...

Ok, so I have a PHP script, and I also have a program written in Pascal, it's compiled in the native executable for whatever OS the server is running. I want to have the user input info and then send that info to the Pascal program to call a function and send the info as parameters. Is there any sort of server side call I can do to do this? Or is my only option making some sort of connection such as SOAP between PHP and the Program? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RTFM for exec(), system(), passthru(), et cetera. <? exec('pascal-file '.$_POST['user_command'],$ret); $ret == 1 ? 'Error detected' ? ''; ?> -- Daniel P. Brown [office] (570-) 587-7080 Ext. 272 [mobile] (570-) 766-8107

Yeah, the first parameter of each function, where you call the executable directly, just has to include the parameters you want to pass to the binary. For example, if you wanted to do the following:

       netstat -pnt
       ls -al|grep -i php
       mv file1.php backups/file2.php

You would (respectively) simply do the following:

       exec('netstat -pnt',$ret);
       exec('ls -al|grep -i php',$ret);
       exec('mv file1.php backups/file2.php',$ret);

Then just eval $ret to see if it was successful (0) or not (1). If you wanted to allow a user to specify parameters, it would be done like so: [PHP] L> File: form.php <? if($_POST['parameters']) { exec('/path/to/pascal-binary '.escapeshellarg($_POST['parameters']),$ret); $ret == 0 ? "Success!" : "Failure!"; exit; } ?> <FORM METHOD="POST" ACTION="<?=$_SERVER['PHP_SELF;?>"> Parameters: <INPUT TYPE="TEXT" NAME="parameters"><BR /> <INPUT TYPE="SUBMIT" VALUE="Process Now"> </FORM> -- Daniel P.

If you can run the executable as a server, you could daemonize it.... <? exec('pascal-binary & 2>&1',$ret); ?> .... and then connect to it using sockets.... but I'm not completely certain that I'm understanding your needs properly. -- Daniel P.
