So, often, I check my accounts for different numbers. For example, my affiliate accounts: I check for cash increase.
I want to program a script where it can login to all these websites and then grab the money value for me and display it on one page. How can I program this?
you should take a look into curl.
You should be able to generate a script that retrieve some webpage easily.
Also take a look into simplexml and dom, it would help you to extract information from (X)HTML files.
Also Zend_Http could be a good alternative to curl.
Cheers
