原始數組:
多重陣列合併成新的數組與關鍵
$cat = Array (
[0] => Array ([id] => 2 [name] => W [pid] => 1)
[1] => Array ([id] => 4 [name] => M [pid] => 1)
[2] => Array ([id] => 5 [name] => C [pid] => 1)
[3] => Array ([id] => 8 [name] => K [pid] => 7)
[4] => Array ([id] => 9 [name] => B [pid] => 7)
[5] => Array ([id] => 12 [name] => X [pid] => 11)
)
我要得到這個結果:
$cat = Array (
[0] => Array (
[pid]=>1,
[item] => Array(
[0] => Array ([id] => 2 [name] => W),
[1] => Array ([id] => 4 [name] => M),
[2] => Array ([id] => 5 [name] => C)
)
),
[1] => Array (
[pid]=>7,
[item]=>Array(
[0] => Array ([id] => 8 [name] => K),
[0] => Array ([id] => 9 [name] => B)
)
),
[2] => Array (
[pid]=>11,
[item]=>Array(
[0] => Array ([id] => 12 [name] => X)
)
)
)
如何?
所以,要合併都具有相同的'pid'的項目?你有沒有嘗試過任何東西?我們喜歡在這裏幫助,但你需要展示你的嘗試。你卡在哪裏?你需要什麼幫助?我們不會爲你做這件事。 –
