Would anyone happen to know how to do interrupt handling in PHP? Say I hit a
button so the script went out somewhere to fetch the data requested, but I
changed my mind and hit 'cancel' to revoke it. Would such a cancellation be
handled as interrupt the same way Ctrl-C is by Unix? Or is there any
get-around to achieve the same result, namely, an aborted action. Thank you
all in advance.
