[asterisk-users] How to recieve number returned by $AGI->wait_for_digit($timeout)

[Zhang Shukun]

hi,

i use $AGI->wait_for_digit($timeout)  to wait for the user press key 1
,and then to do something.

but how can i get the return number ?

is that use $key = $AGI->wait_for_digit($timeout)

and $key will be "200 result=49" if i pressed number 1?

Thanks!
