Yes there is, since PHP can call just about any external application that's accessible to it.
There's a couple functions you'll want to look at. One is exec, and you can learn more about it here:
http://www.php.net/manual/function.exec.php
The other is called PassThru, and you can learn more about it here:
http://www.php.net/manual/function.passthru.php
The primary difference, I think, is that exec just does something and returns true if it actually happens, while PassThru makes the results available to further scripting in PHP.
