$s = array ( 0 => array ( 0 => array ( 0 => '2014-04-11', 'time' => '2014-04-11', 1 => 'BEA01-120N', 'type' => 'BEA01-120N', 2 => 176, 'count' => 176, ), 1 => array ( 0 => '2014-04-11', 'time' => '2014-04-11', 1 => 'BEA21-110N', 'type' => 'BEA21-110N', 2 => 1056, 'count' => 1056, ), ), 1 => array ( 0 => array ( 0 => '2014-04-11', 'time' => '2014-04-11', 1 => 'BEA01-120N', 'type' => 'BEA01-120N', 2 => 192, 'count' => 192, ), 1 => array ( 0 => '2014-04-11', 'time' => '2014-04-11', 1 => 'BEA21-110N', 'type' => 'BEA21-110N', 2 => 960, 'count' => 960, ), ), )
求其type对应的差值和$s[0]及$s[1]的type项的小计。(小计部分已实现,用了unset)
理想得到的结果:
小计的结果: BEA01-120N 176 BEA01-120N 192 差值:176-192 = -16
BEA21-110N 1056 BEA21-110N 960 1056-960 = 96
小计:176+1056=1232 192+960 = 1152
