使用PHP填充Sh脚本值

Question

I have a ready sh script to do some tasks I want, and this sh script shows a menu after execution for example :

Enter 1 to Select Menu 1 or 2 to select Menu 2

 1. Menu 1
 2. Menu 2

Then :

Enter a number to install X addon :

 1. Addon 1
 2. Addon 2

Currently, I use in my PHP script to execute the Sh script :

echo shell_exec('sh /etc/share/nginx/autoload-rev5.sh');

How can I fill the values required by the Sh script from PHP without modifying the Sh script? is it possible ?

Answer 1

You could try using expect - http://php.net/manual/en/expect.examples-usage.php

This is pretty much the same as the expect Linux tool, but you are coding in PHP

You can see some more examples here: http://php.net/manual/en/function.expect-expectl.php

Basically pattern match shell output and on match, submit a predefined response

Answer 2

You can do this using proc_open function. Call it to create a handle on your script (instead of using shell_exec) then parse its output and write what you want to its input.
