値を追加してから、追加された重複を削除して処理する必要がある配列があります。
これが元の配列です...
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 )
)
私がする必要があるのは、この配列を取得し、同じ [PID] 値から [QTY] 値を追加してから、このような配列になることです...
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 )
)
したがって、すべての QTY を追加してから、重複を削除します。
ここで先に進む最善の方法がよくわかりません。助言がありますか?
