将值压入数组的末尾

问题描述

| 我有以下数组，里面满是乱码（我对lorem ipsum感到无聊，所以我开始输入随机的东西-我正在测试__¬）。 我使用MysqLi_fetch_array获取此数组。 [array1]

Array
(
    [0] => Array
        (

            [title] => this is a new thread,and it is great and it should work

            [thread_id] => 27

            [content] => <p>hello,how are you? and what are you doing y\'all and this should work</p> 

            [username] => umar

            [author_id] => 12

            [tags] => Array
                (
                    [0] => lorem
                )

        )

    [1] => Array
        (

            [title] => this is my second thread and it should work fine,just fine

            [thread_id] => 28

            [content] => <p>this is is good,that I think it should have a thread of its own,don\'t you think?</p> 

            [username] => umarrazzaq

            [author_id] => 12

            [tags] => Array
                (
                    [0] => thread
                    [1] => less
                )

        )

)

我还有另一个数组[array2]：

    Array ( [0] => Array (  [replies] => 2  [id] => 27 )
 [1] => Array (  [replies] => 1  [id] => 28 ) ) 

我想将第二个数组推到ID匹配的第一个数组上。 例如 因此，第一个数组将变为：

 [0] => Array
            (

                [title] => this is a new thread,and it is great and it should work

                [thread_id] => 27

                [content] => <p>hello,how are you? and what are you doing y\'all and this should work</p> 

                [username] => umar

                [author_id] => 12

                [tags] => Array
                    (
                        [0] => lorem
                    )

                **[replies] => 2**

            )

我已经尝试过通过引用传递并在foreach循环中使用array_push，但是它只对其中一个起作用。     

解决方法

尝试这个：

foreach($array1 as $key=>&$arr){
    $arr[\'replies\'] = $array2[$key][\'replies\']
}

    ,看来您也可以在桌子上进行JOIN操作

foreach($array1 as $key => $value)
    {
     $array1[$value[\'thread_id\']] = $value;

    }

    foreach($array2 as $value)
    {
      array_push($array1[$value[\'id\']],$value);
    }

    ,如果我的问题正确，那么您想合并array2.id和array1.thread_id相同的数组。在这种情况下，您将无法使用array_merge。除非您将第二个数组更改为如下所示。 数组（ [$ thead_id] =>数组（[回复] => 2） .... ） 那么您可以轻松地使用array_merge。
