PHP script to download attachments from GMAIL (imap)

The php script should take in username, password for a gmail account. It should allow user to specify subject of email. It should then download attachment(s) from last email with that subject. eg: username: user@[login to view URL] password: password subject: billing result: should download the attachments in last email with subject billing to a folder. ## Deliverables the script should be tested and should be able to perform to specification for acceptance by me.
