what are the ways to create web App that will execute shell script smoothly

I am trying to build an web interface to execute the shell script on the linux environment.

I tried the same using the PHP shell_exec("test.sh") but it did not work properly. It is unable to execute few commonds on the test.sh file and if i try executing the test.sh file it works properly though linux terminal.

<?php
   shell_exec(command);
?>

I just want to execute shell script through web interface , language can be any(Php, Java, nodejs..)
