i have two questions.
is it possible to extract row(s) from MySQL and send it via mail.
there is a mail containing data in the table format for a db. is it possible to read the data from the mail or i will have to save the data in a file and do the uploading.
Of course.
yes, assuming your sript is answering the mail. Looko into the imap functions, as well as the filesystem functions (imap_body(), for example.
