can someone in this universe give me the step by step to install PECL for windows on php server, so then i can use the SpiderMonkey js engine to run js within php code?
Unfortunately the pecl4win site lacks due to limited resources. Pierre, our windows build master, creates extensions randomly on request and makes them available via http://downloads.php.net/pierre/ until the new PECL infrastructure is ready.
If you need an extension not available there you might ask on the pecl-dev at lists.php.net mailing list.
Also http://wiki.php.net/internals/windows/stepbystepbuild has some instructions. The build system on windows currentlydoesn't allow building extensions stand-alone, but you have to build from the PHP source tree. For adding oauth you either have to put the sources under php-src/ext/oauth before running buildconf.bat or use the --extra-ext-dir (or similar) option for buildconf.bat.
