I am trying to run a batch file using exec function in PHP. The program statement executes without any error but nothing happen and batch file is not executed.
The batch file is v.simple with just two commands.This batch file runs fine when I run directly from cmd.But when I use exec function from my PHP page, I am unable to run this batch file. I am not interested in the output returned by exec( ) function's argument . I am just interested in the complete execution of the batch file.
I have also tried using the exec() in following way but not successful:
exec("c:\\windows\\system32\\cmd.exe /c $batchFileToRun");
Is there any option available better than exec()?
Can anyone help me?

The exec() function already calls "cmd.exe" internally, there's no need
to call it yourself.
You've managed to omit all the relevant information:
- What $batchFileToRun is. Is it a full path? Is it in a network drive?
Does it contain spaces?
- What the batch file does. Does it read or write files? Does it
interact with the desktop?
- What user you are running PHP as. Is it a command line script? Does
Apache run it as LOCAL_SYSTEM?
- What exec()'s return, output and return status are.
> Is there any option available better than exec()?
Given the question, I'd say proc_open() is "better" than exec(), but
it's way more difficult to use. And it won't execute a script either if
it cannot find it or does not have the appropriate permissions.

To be precise, my batch file named show-preview.bat consist of only two commands:
latex first-program.tex
dvipng first-program.dvi
When I run show-preview.bat from cmd then they run successfully and I obtain the desired result.
But when I use exec('show-preview.bat'); I am finding the following error in apache_error_log:
'latex' is not recognized as an internal or external command, operable program or batch file.
'dvipng' is not recognized as an internal or external command, operable program or batch file.
Whereas both of these commands are working fine from the command prompt......... what you say?
I also tried to pass the absolute path of the bat file within exec() but it also do not work. Any idea?

Let's think about it. If logs complain about "latex" and "dvipng",
doesn't that suggest that the batch file is actually being executed?

Yes you are right! But whats the solution?
I want to know that when the bat file is being run successfully from the command prompt then why not from Php script? On the other hand if I will write some command like for example 'convert picture.jpg newPicture.png' in my batch file and run it from my script using exec(), it works and I get the desired result. (perhaps as 'convert' is from a Windows built-in program)
I have googled this issue and found many people discussed the same issue. People have suggested different solutions that worked for them but still I am struggling. Any good idea will highly be appreciated. Thanks!

Don't you need the absolute paths of latex etc within the batch file?

I have also tried with the absolute path of the latex but no success.

Looks like path problems.
>>> latex first-program.tex
1 2
>>> dvipng first-program.dvi
1 2
1.- Command have no absolute path.
2.- Alsto argument files have no absolute path.
Perhaps from command line you have de argument files in the directory
where you execute the batch? PHP probably have not this path.
The error I think is clear:
'latex' is not recognized as an internal or external command, operable
program or batch file.
If you search "not recognized as an internal or external command" you
will find that 'cmd' is who writes the errors. So. this text is the
result of the php exec command.
path.... put the correct paths and everything will work.

You may be right that the issue is due to inappropriate paths but still I am unable to figure out the problem. As far as giving absolute paths both for command and the file; i have tested it already and it did not work. By the way, right now for the sake of simplicity my php, batch and my first-program.tex files..... all are present in the same folder on the root of www (using wamp)
On google the error, I found the following link which suggest setting up of PATH if you are unable to run the latex command from cmd:

Apache runs with a different path than the windows command line.
Try rewriting the commands in the batch file with complete paths
and then execute it from windows command line and then from Apache.
Then if it doesn't work copy and paste it here (not retyping it).
BTW, to quote the revered Jerry, "this is not a PHP question."

My batch file:
C:\TeX\miktex\bin\latex.exe "E:\wamp\wamp\www\first-program.tex"
C:\TeX\miktex\bin\dvipng.exe "E:\wamp\wamp\www\first-program.dvi"
(BTW I have tried with double back slash as well as with forward slash in the path)
Runs perfectly fine when i just run the batch file from the command line.
But when I try to run the same batch file using the following php line of code:
exec('showpreview.bat');
the apache error log reports
latex.exe: The memory dump file could not be found.
latex.exe: Data: latex.fmt
Now what you say? Where I am wrong?

A strange finding:
Today I found someone with a similar issue on the following link:
http://board.phpbuilder.com/showthread.php?10366149-RESOLVED-Executing-an-a pplication-from-PHP
It suggested to use EasyPhp. I tried with it and everything started working as desired. Thanks to Allah(subhanahu watala).
It is working whether you specify the absolute path or relative path. so doesn't seems to be a 'path' related issue.
After reading the thread mentioned above if some one can identify the real issue then it will be really worthy.

In my opinion this nicely demonstrates (again) why everybody should
install PHP by hand instead of using an "easy" prepackaged
all-in-one-plus-more solution, unless you fully understand it.
It actually costs time in the long run to use "easy" solutions.
Installing PHP by hand isn't that hard, and you learn a lot about the
set-up.
What did you learn now?
Old setup isn't "working", new one with EasyPHP is.
So what? What does that mean?
Why did the old setup not interpret/find your path the way you intended?
I dislike such "solutions" (but I am glad for you it works now).
You should wonder: What you will do when another piece of code doesn't
work as intended?
Will you switch to yet another "easy php install"?
Regards,
Erwin Moller
PS: I have no experience with EasyPHP at all, so maybe it is great.

Backslash is not a escape character in Windows batch.

Your error messages seem to be changing along time... This one suggests
that latex just crashed :-?

If you get a PHP crash then you've hit a bug. And you upgrade/downgrade
to a PHP version after/before the bug was fixed/introduced it's not
surprising that the bug is gone. Who compiled that PHP version does not
look particularly relevant.
