Executing python commands from php script -


I have installed SymPi in the server and from the command line, I was able to execute it I have the following. 

  dragon ./sympy-0.7.5/bin/isympy   
  (This will open a console where I can type mathematical expressions   
  1 + 2   
  (will give 3 as output)   
 My purpose is to do php using  shell_exec . I have written one of the following PHP files, but it is not working.    $ command = escapeshellcmd ('Python ./sympy-0.7.5/bin/isympy'); shell_exec ($ command); $ output = shell_xac ('1 + 2');   
 Help in understanding Why is it not working?  
 Please note that the following script works fine which executes only a python script and retrieves the output.  
  $ command = escapeshellcmd ('Python C: \ Pythonprograms \ test3 py'); $ output = shell_xac ($ command); $ echo output;    
 
 
 My guess is that  shell_exec  is different from that person when you manually Do the execution.  
 Your work example specifies a hard path that will work from anywhere. Whereas your non-working example specifies a relative path ( ./  cwd).  
 Disk to give full path to change your call to  isympy . Or understand how to set cwd for  shell_exec .  
 (If this does not resolve it, then say more than "Not working." What happens? An error? What is the full text of the error?)

This part of the circuit will be combination logic. To use an active-less asynchronous reset and KEY1 to use KEY0 as the clock input, you must store SW15-0in in a 16-bit register in the value The register should be enabled to have a 16-bit positive edge, which uses the embedded D flip-flo
