how to use "request[]"

[pankajkarde]

i am writing the phpagi script .now i want to use the "request" in my script.but i am unable to put it in the script in right way. i want to capture a callerid,i write the script with folowing entries like,

$clid = $agi->request['agi_callerid'];
$agi->swift("Your caller i d is $clid");
echo("Caller ID is $clid");

but it is not working at all.
i am unable to find out the bug.
is their any other entries required in the script.

$clid = $agi->request;

$agi->swift("Your caller i d is $clid");

echo("Caller ID is $clid");

should be:

$agi->conlog("Caller ID is $clid");

using echo() will send output to the AGI stream with asterisk, thus corrupting the AGI protocol.  Use conlog().
