數組一:

[0] => Array

(

[rid] => 1

[hf_rid] => 0

[aid] => 1

[uid] => 1

[content] => 我肯定第一名

[re_time] => 2017-10-10 10:59

[nickname] => 就是這么帥

)

[1] => Array

(

[rid] => 2

[hf_rid] => 0

[aid] => 1

[uid] => 1

[content] => 馬蛋,中槍了

[re_time] => 2017-10-10 01:10

[nickname] => 說定的唉

)

數組二:

[0] => Array

(

[rid] => 3

[hf_rid] => 1

[aid] => 1

[uid] => 1

[content] => 我肯定第一名

[re_time] => 2017-10-10 10:59

[nickname] => 就是這么帥

)

[1] => Array

(

[aid] => 1

[uid] => 1

[content] => ssd發的發的服務

[re_time] => 2017-10-10 01:10

我想把他們合并起來!~具體合并要求是這樣的: 如果數組二的hf_rid字段等于數組一的 rid 字段,那么合并的效果是這樣的

[0] => Array

(

[rid] => 1

[hf_rid] => 0

[aid] => 1

[uid] => 1

[content] => 我肯定第一名

[re_time] => 2017-10-10 10:59

[nickname] => 就是這么帥

[xxxxx]=> Array

(

[rid] => 3

[hf_rid] => 1

[aid] => 1

[uid] => 1

[content] => 我肯定第一名

[re_time] => 2017-10-10 10:59

[nickname] => 就是這么帥

)

)

[1] => Array

(

[rid] => 2

[hf_rid] => 0

[aid] => 1

[uid] => 1

[content] => 馬蛋,中槍了

[re_time] => 2017-10-10 01:10

[nickname] => 說定的唉

[xxxxx]=> Array

(

[0]=>array

(

[rid] => 4

[hf_rid] => 2

[aid] => 1

[uid] => 1

[content] => 馬蛋,中槍了

[re_time] => 2017-10-10 01:10

)

[1] => Array

[hf_rid] => 2

[aid] => 1

[uid] => 1

[content] => ssd發的發的服務

[re_time] => 2017-10-10 01:10

[nickname] => 說定的唉
