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

Array( [0] => Array ( [0] => BEA01-120N [1] => -16 ) [1] => Array ( [0] => BEA21-110N [1] => 96 ))小计你已经做了,我就偷懒了
