方法

$i=-1;
        foreach($list2 as $key=>$value){
            $i++;
            //echo $i;
            //echo $value['min'];
            $list1[$i]['min']=$value['min'];
        }
        
        $i=-1;
        foreach($list3 as $key=>$value){
            $i++;
            //echo $i;
            //echo $value['min'];
            $list1[$i]['start']=$value['price'];
        }
        
        $i=-1;
        foreach($list4 as $key=>$value){
            $i++;
            //echo $i;
            //echo $value['min'];
            $list1[$i]['end']=$value['price'];
            $list1[$i]['date']=$value['date'];
        }
        
        //$list1['0']['min']="123";
        //$list1['1']['min']="456";
        print_r ($list1);

结果

            [min] => 11
            [start] => 11
            [end] => 50
            [date] => 2016-01-07
        )

    [1] => Array
        (
