Hello

Then we made a upgrade fr?n Redhat 7.0 and PHP 404 this syntax stopped to work. It keep tellning me that the command failed. 


      if(system($cmd))
        $Msg.="The command was successful.";
      else
        $Msg.="Nope it didnt worked.";

What does $cmd actually return?  system() returns the last line of output from the command, which will evaluate to false for things like "0" or "".  Try using exec() and printing the output from there if you are unsure.

The problem is that I used exec() before the update and it worked fine. I have another script that does the same thing that script doesnt work anymore either.

No other employee at my work have changed the file so the update is the only thing I can think of to blame.

Plenty of things changed, including a lot of stuff with Redhat 7.0 -> 7.1.  Did you recompile PHP after the upgrade?

Again, what does $cmd actually return?  Also, try :
   $line = system($cmd,$retvar);
   $msg = "system($cmd) --> $retvar, $line";
and tell me what it says
