how to pass an array from php to flex?

hi,

i have a php script that returns ok an array as $myarray['key1']['key2'], i tested it with an loop and echo, so it's really fine in php part...also my amfphp is running ok, already tested.

BUT, in flex, i can't receive the array....my php function has a return, but when i use myRemote.mygetMethod(); i get [object AsyncToken] instead of array...

how can i send an simple php array to flex trough amfphp?

thanks
