Hello, I'm designing a website with php and the critical point of the design
is to execute a program in the server, so after execution is finished,
server will show the client some data and info.
The program is called pspice, which analizes electronic circuits, works in
msdos and in order to call him you need to write in the command the input
file (which is created before we call the program) and the output file,
which can have the same name as the input file, since they have a different
extension. If everything works correctly after the execution of the proper
command, a .out (the output file written in the command) file should be
created with the data the server would later provide to the client.
I have got to execute the program using the line:
exec('c:\WINDOWS\\SYSTEM32\\cmd.exe /c start c:\\PHP\\PSPICE\\pspice1.exe
ej1 ej1')
The problem I have is that the execution never ends. The cmd window with the
execution of the program appears and never ends, just keep simulating (and
the execution should be over in less than a second). The .out file is
created but it is empty. How can I make the execution of the program stop
and continue executing the rest of the code of my php file?
Thanks!
