在php中更新多维索引数组

Question

因此，我不确定这是否是最佳方法，但我正在为客户端构建一个 Web 应用程序，该应用程序将从数据库中获取数据（股票名称、股票价格、用户购买的股票、购买日期）并显示股票价格 X 每个月购买的股票。我遇到的问题是 eaxh 股票有单独的条目。因此，例如，如果用户在 4 月和 5 月再次购买了 facebook 股票，则会创建两条记录。我希望能够通过将每个月的值合并到代表该股票的单行中，将数据合并到显示每只股票每月购买价格的表中的单行中。

我尝试了各种方法来处理数组，但找不到基于股票名称合并数组的方法。 php有办法做到这一点吗？

代码如下：

<?php
// TEMPLATE NAME: TEST REPORTS
get_header();
$get_contributions = 'y';
$get_withdrawls = 'y';
$run_report = 'y';
$i = 0;
global $wpdb;
// GET USER DATA
$get_user_data = "SELECT * FROM $wpdb->users";
$get_user_data_results = $wpdb->get_results($get_user_data);
?>
<table style="width: 98%; margin: 40px auto;"><tbody style="width:100%;">
<tr style="text-align:center;">
<td style="width: 7%;">Name</td><td style="width: 7%;">January</td><td   
style="width: 7%;">February</td><td style="width: 7%;">March</td>
<td style="width: 7%;">April</td><td style="width: 7%;">May</td><td

<?php
// LOOP THROUGH USER DATA 
foreach($get_user_data_results as $user_results):

$user_id = $user_results->ID;
$get_stock_data = "SELECT * FROM nli_user_stocks WHERE user_id

$get_stock_results = $wpdb->get_results($get_stock_data);

if($get_contributions == 'y'){
// SET VARIABLES FOR MONTHLY CONTRIBUTIONS   

$company_stock_symbol = array();

foreach($get_stock_results as $stock_results):

break;

} 

$add_array_values = array($stock_symbol, $month, $purchase_price, $jan,  
$feb, $mar, $apr, $may, $jun, $jul, $aug, $sept, $oct, $nov, $dec,

array_push($company_stock_symbol, $add_array_values);

endforeach;
} // endif

foreach($company_stock_symbol as $stock_infoB):

if($i%2==true){

$i++;
endforeach;
endforeach;?>
</tbody></table>
<?php
get_footer();
?>

输出如下：

Stock Reports Page

感谢所有帮助。我最终在一个新创建的表上使用了 JOIN，经过一整天没有进展，感谢这个社区的帮助，今天取得了很大成就。
