How to change IP address using network-shell with argument as IP

Question

I am trying to run the below batch script using PHP (it runs fine from command prompt) to change the IP using the argument passed

@echo off
setlocal enabledelayedexpansion
netsh int ip set address "EDU_LAN_Connection" static 172.31.%1.110 255.255.255.0 172.31.%1.1 1

In PHP:

 system("cmd /c C:\EDU_Project\change_ip.bat 6");

I get the following error when running the PHP script:

Invalid address parameter (172.31.61.1 1). It should be a valid IPv4 address.

I am not sure how to use delayedexpansion with argument. Please help !

I think you should look into how IPV4 addresses are formatted — Daryl Gill, Jan 26 '15 at 20:50
you're trying to assign a class B address, which is all fine. A standard class B address would be (172.x.y.z), You're currently doing 172.x.y.z A, where A is. Is invalid for an IP construct, hence my original comment — Daryl Gill, Jan 26 '15 at 20:55
This error is same as discussed in this question: http://stackoverflow.com/questions/21824179/ip-configuration-from-batch-file but I am not sure how to use arguments with delayedexpansion — Chetan, Jan 26 '15 at 21:00

Batch parameters are addressed with %1 only. Not %1%

Change your batchfile accordingly:

 netsh int ip set address "EDU_LAN_Connection" static 172.31.%1.110 255.255.255.0 172.31.%1.1 1

Thanks I made that change, script runs fine on command prompt but I still get this error when ran from PHP: Invalid address parameter (172.31.6.110 255.255.255.0 172.31.6.1). It should be a valid IPv4 address. Ping request could not find host 172.31.6.1 -n 2. Please check the name and try again. – Chetan Jan 26 '15 at 20:57
I have edited a typo in my answer. Try again please. – Stephan Jan 26 '15 at 21:09
Thanks for the help Stephan, yeah I already saw that typo it still does not work. Works fine on command prompt though. – Chetan Jan 26 '15 at 21:10
The error though has changed to this: Invalid address parameter (172.31.6.110 255.255.255.0 172.31.6.1). It should be a valid IPv4 address – Chetan Jan 26 '15 at 21:12
I can see no reason for this. But I notice, that the last "1" (for "metric") is missing. – Stephan Jan 26 '15 at 21:46

Instead of going for system function and passing an argument to the batch file. I ran the netsh command directly from PHP using shell_exec:

$var= 18;
shell_exec('netsh int ip set address name=\"EDU_LAN_Connection\" static 172.31.'.$var.'.110 255.255.255.0 172.31.'.$var.'.1 1');
