Build static into PHP

Extract source tarball to PHP source tree (under ext/ directory) and rebuild PHP with commands

rm ./configure
./buildconf --force
./configure --with-sapnwrfc=<path to nwrfcsdk> (+ your configuration directives)
make

As a dynamic extension

Extract source tarball to some directory and build dynamic module with commands

cd <sapnwrfc dir>
phpize
./configure
./configure --with-sapnwrfc=<path to nwrfcsdk>
make 
make install

Enable sapnwrfc extension editing your php.ini

extension = sapnwrfc.so

see also the example build.sh

Windows

Install the SAP NW RFC SDK

  • Get the SAP NW RFC SDK from http://service.sap.com.
  • Extract the SDK archive with SAPCAR
  • Copy the *.dll files from the lib folder to (just use the same like your PHP installation)
    • x86 (32bit): C:\Windows\system32
    • x64 (64bit): C:\Windows\SysWOW64

Install the precompiled PHP extension

  • copy the right compiled version php_sapnwrfc_*.dll from builds to your php/ext folder
  • active it in your php.ini (extension = php_sapnwrfc_*.dll)

Build it on your own

NOTE: This is harder than you think :-)

  • download SAP NW RFC SDK (i used 7.2.xxx)
    • extract with SAPCAR.exe to C:\SAP\sapcar_x86\nwrfcsdk (for x64 C:\SAP\sapcar_x64\nwrfcsdk)
  • get PHP "Development package (SDK to develop PHP extension)" http://windows.php.net/snapshots/
    • install to C:\php-sdk\phpdev\vc11\x86\php-5.6.9-dev-devel-VC11-x86
  • install VS2012 (can be express for free)
    • create a new project (Visual C++ -> Win32 Project -> choose DLL -> choose empty project)
    • add the files from php-sapnwrfc to the project (i think php_sapnwrfc.h and sapnwrfc.c are enough, but i copied all)
      • also add them not just to folder, but to the header files!
    • add c++ paths for *.h files
      • C:\SAP\sapcar_x86\nwrfcsdk\include;
      • C:\php-sdk\phpdev\vc11\x86\php-5.6.9-dev-devel-VC11-x86\include;

      • C:\php-sdk\phpdev\vc11\x86\php-5.6.9-dev-devel-VC11-x86\include\sapi;
      • C:\php-sdk\phpdev\vc11\x86\php-5.6.9-dev-devel-VC11-x86\include\main;
    • Declare c++ preprocessors:
