- PHP code
$_arr = array( '1' =>array( 'zk'=>'0.5', 'mx'=>array( array('sku_id'=>'001','zk'=>'0.5'), array('sku_id'=>'002','zk'=>'0.5'), array('sku_id'=>'006','zk'=>'0.5'), ), '2' =>array( 'zk'=>'0.8', 'mx'=>array( array('sku_id'=>'003','zk'=>'0.8'), array('sku_id'=>'004','zk'=>'0.8'), ), ));[解决办法]
