因此,我正在爲正在開發的項目開發一個消息系統,並且希望通過最新消息datetime組織一組對話。按數組值排序多維數組
這裏是我的數組:
Array(
[0] = Array (
[ID] => 1,
[USER] => 1,
[AUTHOR] => 2,
[TITLE] => Welcome to the Site!,
[DATETIME] => 2016-09-12 20:41:16,
[MESSAGES] => Array (
[0] => Array (
[ID] => 1,
[CONVERSATION] => 1,
[USER] => 1,
[CONTENT] => Welcome to the site User!,
[DATETIME] => 2016-09-13 00:19:20
)
[1] => Array (
[ID] => 2,
[CONVERSATION] => 1,
[USER] => 2,
[CONTENT] => Thanks for welcoming me!,
[DATETIME] => 2016-09-13 00:27:54
)
)
[1] = Array (
[ID] => 2,
[USER] => 2,
[AUTHOR] => 1,
[TITLE] => Hello World!,
[DATETIME] => 2016-09-13 00:29:59,
[MESSAGES] => Array (
[0] => Array (
[ID] => 1,
[CONVERSATION] => 1,
[USER] => 1,
[CONTENT] => This is a test post.,
[DATETIME] => 2016-09-13 00:19:45
)
[1] => Array (
[ID] => 2,
[CONVERSATION] => 1,
[USER] => 2,
[CONTENT] => This is an example response.,
[DATETIME] => 2016-09-13 00:45:04
)
)
)
我想要做的是組織使用的是最新消息的日期時間談話的數組,以便與最新的消息談話會首先,與第二大部分的談話最近的消息將是第二個等等。我一直在尋找不同的功能,如
array_multisort
array_sort
usort
我已經找到其他的解決方案在線,但他們不完全匹配什麼我在尋找因此,沒有人知道組織這些聊天信息的最佳方式?
也許這有助於http://stackoverflow.com/questions/20805143/php-converting-multidimensional-array-to-modified-pre-order-traversal-tree –
我不知道如何實現它到我的代碼, 能否請你幫忙? – Elxafil
