Rscript does not work when invoked in PHP but does from Command Prompt

I am trying to execute an R script from my PHP page using the exec function. I have set the environment variables in Windows and Rscript works fine on the command prompt. However on the PHP page it says, " 'Rscript' is not recognized as an internal or external command, operable program or batch file."

Any help would be greatly appreciated.

Solution

  • I would define a launcher.bat where I deal will all R-paths problem:

    PATH PATH_TO_R/R-version/bin;%path%
cd PATH_TO_R_SCRIPT
Rscript myscript.R arg1 arg2

    Then in the php side you can use exec:

       <?php
exec('c:\WINDOWS\system32\cmd.exe /c START PATH_TO_LAUNCHER\LAUNCHER.bat');
?>
