如何使用循环将 php 数组插入到另一个数组中？

Question

<?php
 include_once("connect.php");
$query = "
select date, sum(amount) as total
from expenses
where date <= NOW()
and date >= Date_add(Now(),interval - 7 day)
group by date;";
    $dateArray = Array();
    $result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
  // output data of each row
  while($row = mysqli_fetch_assoc($result)) {
    echo $row["total"];
    echo $row["date"];
      array_push($dateArray,$row);
  }}

echo $dateArray[0]["total"];
$dataPoints = array(
    array("y" => 25, "label" => "Sunday"),
    array("y" => 15, "label" => "Monday"),
    array("y" => 25, "label" => "Tuesday"),
    array("y" => 5, "label" => "Wednesday"),
    array("y" => 10, "label" => "Thursday"),
    array("y" => 0, "label" => "Friday"),
    array("y" => 20, "label" => "Saturday")
);
 
?>

我试过运行它像这样但出现错误，所以不确定我是否可以将每个数组元素“y”设置为数量之一并将“标签”设置为唯一日期，例如这个

$dataPoints = array(

foreach($dateArray as $item) {
 array("y" => $dateArray("amount"), "label" => $dateArray("date"))
}
)

Answer 1

尝试如下：

$dataPoints = array();
foreach($dateArray as $item) {
    array_push($dataPoint, array("y" => $dateArray("amount"), "label" => $dateArray("date")));
}
