HTTPAPI libraries for PHP and Python

As you looked at the examples earlier in the chapter, you may have thought that while there might be a lot of power in this httapi thing, you really don't want to learn another XML format to control FreeSWITCH. Also, manually printing all of that XML could be a huge hassle. That's why the httapi XML was written to be easy to implement with a helper library in the language of your choice.

A couple of such libraries exist, for PHP and for Python. Both libraries were developed by Raymond Chandler, and you can find them in the freeswitch-contrib GIT repository, under the directory intralanman. To download the libraries and the examples (and a whole lot of other good stuff):

cd /usr/srcgit clone https://freeswitch.org/stash/scm/fs/freeswitch-contrib.gitcd freeswitch-contrib/intralanman

There you'll find a PHP and a Python directory. Both PHP and Python libraries are composed by one only file (phttapi.php and httapy.py), for ease of use.
