Re: [PHP] About exec function

[Richard Lynch]

The PHP User probably does not have write access to the new .out file
it just created.

Why Windows would be this weird, and let you create a file you cannot
write to is beyond my comprehension, but there it is...

If it's a multi-user Windows box, try logging in as the user PHP runs
as, which is IUSER_machinename, I think, on some Windows boxes...

exec() also takes 2 more arguments, which pass back output and error
code.

If Windows is giving any kind of error message and or OS error code,
you can get them by using those 2 args.

Do this first, actually, as it is better than just guessing what went
wrong.

 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!

exec() will block until you command finishes - which it never does,
this is not a problem with exec() or php but rather with the cmdline
app you are calling - or more likely due to the way you are calling the
cmdline in your example.

I'm guessing it should be this instead (if it's not then it's time for you to
read the cmd.exe and/or start.exe man pages :-) :

exec('c:\WINDOWS\\SYSTEM32\\cmd.exe /c c:\\PHP\\PSPICE\\pspice1.exe ej1 ej1');
