Can I send a fax using PHP?

Question

I have fax numbers and I would like to to send a fax message to each of the numbers programatically.

What is the code to send fax message using PHP?

Answer 1

As fax is not internet-based like email, there is no easy way to do this, like you can send emails using mail().

You can, though, use PHP to talk to an internet fax service, as described here: http://www.interfax.net/en/dev/php

Answer 2

You could interface with Hylafax and let it do the actual job.

An example of successful implementation is AvantFAX. It's open source, so you can look at the code and see how they did it.
