Question

我想知道是否有人可以帮助解决我遇到的概念问题，或者是否有更好的方法。基本上我通过搜索栏在数据库中搜索一系列术语。我有一个循环遍历每个术语的函数，然后将其用于搜索。它将所有内容放在一个数组中，然后返回数组，然后将其处理成一个表。搜索工作正常，我插入条款，它循环通过他们将行推入数组。现在，因为我正在推进不同的数组，我所拥有的父数组具有索引键，我想将其更改为术语的键，并且在数组中有两个其他数组1用于结果数量，另一个用于结果。

我的搜索返回一个数组，打印时看起来像这样：

Array(
     [0]=>Array
               (
                [resultNum]=>1
                [rowArray]=>Array(
                                  [0]=>1
                                  [userid]=>1
                                    etc
                                     )
                  )
     [1]=>Array
               (
                [resultNum]=>1
                [rowArray]=>Array(
                                  [0]=>2
                                  [userid]=>2
                                    etc
                                     )
                  )

我想将两个外部数组的键[0],[1]放入通过getResults($array)函数循环中使用的搜索项中。有什么想法吗？

Answer 1

更改

array_push($totalResults, $sqlResults);

为：

$totalResults[$array[$i]] = $sqlResults;

使其成为关联数组而不是索引数组。

P.S。您应该学会使用foreach循环数组元素，并使用预准备语句来阻止SQL注入。

此外，selectResults()仅返回查询的最后一行。它应该是：

   } else {
        $numresults = mysqli_num_rows($result);
        $outputArray['resultNum'] =  $numresults;
        $outputArray['rowArray'] = array();
        for ($i = 0; $i < $numresults; $i++)
        {
            $row = mysqli_fetch_array($result);
            array_push($outputArray["rowArray"], $row);
        }

这样它每次都会返回所有行而不是覆盖rowArray。

将数字数组键更改为$ variable
