javascript - 我想要 foreach 在数组中

Question

我想在数组中添加 include foreach，我该怎么做

<?php

    foreach($query as $row)
    {
        $cat=$row->categoery:
        $expenses=$row->expenses;

    }

我如何在这个$jsondata中使用这个foreach循环？

我确实喜欢这个

foreach($query as $row)
{
    $cat=$row->categoery:
    $expenses=$row->expenses;

    $jsonData = array
    (
        array("$cat", $expenses),
    );
}

Answer 1

您只需按照每次迭代的操作重新初始化 $jsonData。

$jsonData = array();

foreach($query as $row){
   $cat=$row->categoery:
   $expenses=$row->expenses;

   $jsonData[$cat] = $expenses;
}
