如果两对具有相同的值,则将两对合并到同一个数组中
Merge two pairs in the same array if the pairs have the same value
我有以下几对,它们在同一个数组中:
[
["ID" => 0, "User" => "Test" , "Type" => 3, "Target" => "Caris"],
["ID" => 1, "User" => "Test1", "Type" => 3, "Target" => "Caris"],
["ID" => 2, "User" => "Test2", "Type" => 4, "Target" => "Shirone"],
["ID" => 3, "User" => "Test3", "Type" => 3, "Target" => "Caris"]
]
我想得到它们的种类,所以我使用了下面的代码:
$SortList = [];
foreach($Notif as $Key => $Value)
array_push($SortList, ['Type' => $Value['Type'],
'Target' => $Value['Target']]);
得到这个:
[
["Type" => 3, "Target" => "Caris"],
["Type" => 3, "Target" => "Caris"],
["Type" => 4, "Target" => "Shirone"],
["Type" => 3, "Target" => "Caris"]
]
但我真正想要的是这样的:
[
["Type" => 3, "Target" => "Caris"],
["Type" => 4, "Target" => "Shirone"]
]
如果它们的值相同,我想合并它们,
(array_merge()
好像只能用于非对)
如何像上面那样合并它们?
$SortList = [];
foreach($Notif as $Key => $Value) {
// Just save only value for the same pair, use them concatenated as the key
$SortList[$Value['Type']."_".$Value['Target']] =
array('Type' => $Value['Type'], 'Target' => $Value['Target']);
}
// remove extra stuff (the keys) that was added to prevent duplicates
$SortList = array_values($SortList);
