我有一个数组,我需要通过添加值来处理它,然后删除任何添加的重复项。
这是原始数组...
Array (
[0] => Array ( [PID] => 2872 [QTY] => 1 )
[1] => Array ( [PID] => 3145 [QTY] => 2 )
[2] => Array ( [PID] => 3107 [QTY] => 1 )
[3] => Array ( [PID] => 2739 [QTY] => 1 )
[4] => Array ( [PID] => 3137 [QTY] => 1 )
[5] => Array ( [PID] => 3107 [QTY] => 1 )
[6] => Array ( [PID] => 2739 [QTY] => 1 )
[7] => Array ( [PID] => 3107 [QTY] => 1 )
[8] => Array ( [PID] => 3137 [QTY] => 4 )
[9] => Array ( [PID] => 3551 [QTY] => 1 )
[10] => Array ( [PID] => 3107 [QTY] => 1 )
[11] => Array ( [PID] => 3107 [QTY] => 1 )
[12] => Array ( [PID] => 3137 [QTY] => 1 )
[13] => Array ( [PID] => 3551 [QTY] => 2 )
[14] => Array ( [PID] => 3136 [QTY] => 1 )
[15] => Array ( [PID] => 3137 [QTY] => 1 )
[16] => Array ( [PID] => 3032 [QTY] => 1 )
[17] => Array ( [PID] => 3551 [QTY] => 1 )
[18] => Array ( [PID] => 3107 [QTY] => 1 )
[19] => Array ( [PID] => 3459 [QTY] => 1 )
[20] => Array ( [PID] => 3141 [QTY] => 1 )
[21] => Array ( [PID] => 2724 [QTY] => 1 )
[22] => Array ( [PID] => 2743 [QTY] => 1 )
[23] => Array ( [PID] => 3139 [QTY] => 2 )
[24] => Array ( [PID] => 3137 [QTY] => 2 )
[25] => Array ( [PID] => 3107 [QTY] => 1 )
)
我需要做的是获取这个数组并从相同的 [PID] 值中添加 [QTY] 值,然后在此之后得到一个像这样的数组......
Array (
[0] => Array ( [PID] => 2724 [QTY] => 1 )
[1] => Array ( [PID] => 2739 [QTY] => 2 )
[2] => Array ( [PID] => 2743 [QTY] => 1 )
[3] => Array ( [PID] => 2872 [QTY] => 1 )
[4] => Array ( [PID] => 3032 [QTY] => 1 )
[5] => Array ( [PID] => 3107 [QTY] => 7 )
[6] => Array ( [PID] => 3136 [QTY] => 1 )
[7] => Array ( [PID] => 3137 [QTY] => 9 )
[8] => Array ( [PID] => 3139 [QTY] => 2 )
[9] => Array ( [PID] => 3141 [QTY] => 1 )
[10] => Array ( [PID] => 3145 [QTY] => 2 )
[11] => Array ( [PID] => 3459 [QTY] => 1 )
[12] => Array ( [PID] => 3551 [QTY] => 4 )
)
所以添加所有数量然后删除重复项。
我不太确定在这里进行的最佳方式。有什么建议么?
