- Make sapi_module available to external modules (PHPAPI) - Make the php.ini path reported in phpinfo() always point to real full path of the php.ini file - Optimized the ISAPI module not to read unnecessary server variables and read necessary variables at most once.
Each SAPI backend has to contain: config.m4: just like for extensions, this file contains autoconf directives that end up in the configure script. The only difference is that the sapi config.m4 files are read in diversion (output block) 2 instead of 3. The sapi config.m4 files should set two variables: PHP_SAPI (which sapi backend to choose) and INSTALL_IT (the actions performed when "make install" is executed). If they are not specified, they will default to "cgi" and "do nothing," respectively. Additionally, the following m4 macros can be used to influence what is created during "make": PHP_BUILD_SHARED -- build shared target $SAPI_SHARED PHP_BUILD_STATIC -- build static target $SAPI_STATIC PHP_BUILD_PROGRAM -- build executable $SAPI_PROGRAM (paths relative to top build dir)
