i want to send bitcoin to more than one address, i want to use minimum free for transaction and im using settxfee but it is has no effect.
Code :
$wallet->settxfee((double)0.00001000);
$wallet->sendmany("", $params);
What is the problem ?
Note : I can send bitcoin to all addresses but the fee is too high
AFAIK that command doesn't have any effect for low priority transactions when setting that fee could prevent the TX from being confirmed.
Anyway you can try adding "paytxfee=0.00001000" to your bitcoin.conf.
