我正在尝试转换产品数据的多维数组，其中将PayPal电子邮件设置为数组值之一（某些值可能相同）。我需要帮助将这些合并为其中paypal_email键相同的数组。这是我拥有的数组的print_r。

我需要将数组合并为多维数组，并以贝宝电子邮件作为键，将其他数据作为值。例如，

[total_tax] => 2.66
[paypal_email] => thisismytestpaypal@sandbox.com
[vendor_id] => 2
[shipping] => Array
(
[shipping_total] => 25.00
[shipping_tax] => 2.22
)
)
[1] => Array

$orders = [.....]; //your array
$mappedOrders = [];
foreach($orders as $order) {
$mail = $order['paypal_email'];
if(!isset($mappedOrders[$mail])) { $mappedOrders[$mail] = []; } //create new array in map if $mail index not exists
$mappedOrders[$mail][] = $order; // push order into array for mapped array
}
var_dump($mappedOrders);

进行数组键检查循环
$result = [];
foreach ($array as $value) {
$email = $value['paypal_email']; // Get email
if (!array_key_exists($email, $result)) { // Check if already on the result array
$result[$email] = []; // Create new array with email as key if not
}
$result[$email][] = $value; // push value to email key
}
print_r($result);

考虑由变量$array保留的第一个数组。然后使用简单的foreach循环对其进行迭代，并将数据作为键传送到新数组$newArray，并在paypal_email节点中使用键作为值。代码应为：
$newArray = [];
foreach ($array as $value) {
$newArray[$value['paypal_email']][] = $value;
}
print_r($newArray);

<?php
$data =
[
[
'name' => 'John',
'email' => 'thebeatles@example.com'
],
[
'name' => 'Ringo',
'email' => 'thebeatles@example.com'
],
[
'name' => 'Mick',
'email' => 'thestones@example.com'
],
[
'name' => 'Keith',
'email' => 'thestones@example.com'
],
];
$grouped_by_email = [];
foreach($data as $item)
$grouped_by_email[$item['email']][] = $item;
var_export($grouped_by_email);
输出：
array (
'thebeatles@example.com' =>
array (
0 =>
array (
'name' => 'John',
'email' => 'thebeatles@example.com',
),
1 =>
array (
'name' => 'Ringo',
'email' => 'thebeatles@example.com',
),
),
'thestones@example.com' =>
array (
0 =>
array (
'name' => 'Mick',
'email' => 'thestones@example.com',
),
1 =>
array (
'name' => 'Keith',
'email' => 'thestones@example.com',
