php exec is not executing the command

Question

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    gt        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  lt       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

I already said that I was new to exec   function  After doing some more digging  I came upon 2 gt  amp 1 which needs to be added at the end of command in exec     Thanks  mattosmat for pointing it out in the comments too  I did not try this at once because you said it is a Linux command  I am on Windows    So  what I have discovered  the command is actually executing in the back-end  That is why I could not see it actually running  which I was expecting to happen    For all of you  who had similar problem  my advise is to use that command  It will point out all the errors and also tell you info details about execution   exec  some command 2 gt  amp 1    output   print r  output       to see the response to your command   Thanks for all the help guys  I appreciate it
