If you have troubles installing the php extension, there is an alternative package which tries to implement the same API as pure-php library and can be installed via Composer: phpxmlrpc/polyfill-xmlrpc
These functions can be used to write XML-RPC servers and clients. You can find more information about XML-RPC at » http://www.xmlrpc.com/, and more documentation on this extension and its functions at » http://xmlrpc-epi.sourceforge.net/.
This extension is EXPERIMENTAL. The behaviour of this extension including the names of its functions and any other documentation surrounding this extension may change without notice in a future release of PHP. This extension should be used at your own risk.
