How to use COM objects with PHP4???

One of the new features of PHP4 is the ability to use COM objects. At least I will be able of using an activeX module of our bank (POS). The problem is that I can't find documentation about how to access the COM objects installed in the system. I remember a script when PHP4 was a alfa in the Zend page that uses COM to manage MS Word. Anyone know were I can find documentation or an example??? Thanks in advance. -- \|||||||/ Guillermo Pérez Pérez < o o > - bisho@onirica.com \ L / - bisho@eurielec.etsit.upm.es -oOOo-------oOOo- Onírica: Análisis, diseño e implantación de soluciones informáticas http://www.onirica.com
