Create attached tab delimited file containing submittal in e-mail?

This is a feature request hoping some bright mind can point me in the correct direction. I need to collect data in a webform and import the collected data into an existing pdf form. I can import a single record of tab delimited data into the pdf properly. What I would like to do is, along with the normal submittal data in the e-mail is also to create a tab-delimited file containing the data and attach it to the email. Each submittal would create an attached file to import into my pdf form. Possibly using some php code in the extended processing of the form. I haven't found any ways to do this by searching the issues. Is this possible? Any ideas? Thanks in advance, Dave
