Calling Msbuild from Php - Wrong Codepage and Culture

Question

I have a Php script that calls Msbuild via System:

<?php
system( "msbuild umlaut.proj" );
?>

This is the project file:

<?xml version="1.0" encoding="UTF-8"?>
<Project 
  xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
  DefaultTargets="EchoUmlaut" 
  ToolsVersion="3.5">
  <Target Name="EchoUmlaut">
    <Message Text="Umlaute: Ä Ö Ü ä ö ü ß" />
  </Target>
</Project>

When I call Msbuild directly from the command line the output of msbuild is in German (as excpected) and the umlauts come out OK (I chcp to 1252). But when I use php to call msbuild the umlauts are wrong, and the output of msbuild is changed to English. I wonder what I can do to prevent this.

C:\>chcp
Aktive Codepage: 1252.

Looks like the php script is not passing in some of the environment variables that the shell passes in. You will need to set them manually using putenv:

bool putenv  (  string $setting  );

copy them from the shell and paste them into the script before calling system.
