I urgently need a php file that accesses an aweber list to check if an email address is registered in the list via the aweber api.
The value returned should be a boolean True or False.
Visitor comes to our site, they enter in their email address via a form into a variable (this bit is completed already).
I then need to pass this variable to a php file that calls the aweber api, selects the right list in aweber and returns back a 'True' value if the email address is found or a 'False' value if the email address was not found in the list.
Developer must be experienced with the Aweber API and PHP, knows how to install/use the Aweber API library and can do a fast turn around (2 days max) for this simple project.
