php post dumper.
a post-dump back-up strategy for browser crashes..
When someone at your site POSTs something (from any form) this script dumps
the posted textarea to a file. Of course it works for your posts, too.
So, if your browser ever crashes, as they do, you can get back that 'lost post',
blog, comment, whatever it was. You could recover text that your users 'lost'
too, and also see things which they previewed, but *didn't* post. 8)
Also handy for catching potential spammers. You'd be amazed the things that
people use your site's forms for, often automatically, things that one would
not normally see, at least with a decent spam-preventionsystem in-place.
How does the dumper know which post variable is the textarea? It doesn't, it
simply calculates the length of all variables in the POST array, and dumps the
*longest* one, works brilliantly.
I wish I had this ten minutes ago!
Make fun, now.
