[php] php exec() is not executing the command

I have tried to use exec() with 'whoami' to check if it works and I got the result of

nt authority\system

Now I need to run a .exe file with parameters from php via exec() function.

I tried this in command prompt and it actually runs the program with given parameters. This is the example command.

NOTE the exe file gets 3 inputs (folder, file_name, report_file_nmae)

> ..\..\some_file.exe folder="C:\path_to_folder" param=1.xml report=2.xml

But when I run this command from php file:

exec('..\..\some_file.exe folder="C:\path_to_folder" param=1.xml report=2.xml');

nothing is happening. This is the first time I am using exec() function, so I am not familiar with its details. What is wrong?

I tried using:

• \\ instead of \
• escapeshellarg() on the directory
• added "" around directory folder names

No luck

Addendum:

echo exec($command)  // echos < .... why?

or

exec($command, $output);
print_r($output);        // Array()

I even changed the permission on the file to full control to all users. If I call the program from command prompt, I can see the icon appearing next to clock for a second.

But the same call from php will not even call the program.

Edit

Even exec('notepad.exe'); is not working. Something has to be done with php configurations maybe?

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.
