现有：
$arr = array(
     array('101-1148713','-68500','高岩'),
     array('101-1148713','-1464.6','高岩'),
     array('101-1148712','11','高岩'),
     array('101-1148713','98500','高岩'),
     array('101-1177035','-11068.4','全玮')
);
我怎么转化为
$arr = array(
    '高岩'=>array(
         '101-1148713'=>array('-68500','-1464.6','98500'),
'101-1148712'=>array('11');
    ),
'全玮'=>array(
         '101-1177035'=>array('-11068.4')
    )
);
回复讨论(解决方案) $arr = array( array('101-1148713','-68500','高岩'), array('101-1148713','-1464.6','高岩'), array('101-1148712','11','高岩'), array('101-1148713','98500','高岩'), array('101-1177035','-11068.4','全玮'));foreach($arr as $v) { $res[$v[2]][$v[0]][] = $v[1];}print_r($res);
array( [高岩] => array ( [101-1148713] => array ( [0] => -68500 [1] => -1464.6 [2] => 98500 ) [101-1148712] => array ( [0] => 11 ) ) [全玮] => array ( [101-1177035] => array ( [0] => -11068.4 ) ))
