Well it all started with fincheck the shell script originally by Enzo Michelangeli And then further developed by me Simon G and Krystian Kowalczuk.
That shell script (Ver. 20080625) is available here http://www.simong.net/finarea/fincheck.
Well now I have developed some functions to do the same, but in a different language. PHP
So far (2008 June 22nd), it can send an sms(+ delayed sms with caller-Id), make a call, set and check you callforwarding and check your credit in cents.
It also understands time-zones, GMT and Summer/Wintertime, unlike Betamax/Finarea.
The php source script is here http://www.simong.net/finarea/fincheck.phps. Or http://www.simong.net/finarea/fincheck.php.txt for a text version.
And the example usage script http://www.simong.net/finarea/example.phps or http://www.simong.net/finarea/example.php.txt for a text version.
Did you know that you can run a php script just like a shell script ?
/pathToPHP/php fincheck.php 'cmd=creditcents&usernumber=1&auth=yoursecret'
