php - 对 foreach 中的项目进行分组并创建数组

Question

在下面的示例中，我循环遍历具有以下输出的 MySQL 查询的结果:

这是我迄今为止拥有的 PHP:

foreach ($customers as $customer) {

  if($customer['innumber'] != null){

      $chartInbound['name'] = $customer['name'];
      $chartInbound['label'] = $customer['innumber'];
      $chartInbound['count'] = $customer['count'];
      $chartInbound['customerid'] = $customer['id'];

      array_push($out['chartInbound'], $chartInbound);
   }
}

print_r($out['chartInbound']); 的输出为:

Array
(
[0] => Array
    (
        [name] => 1st Online Solutions
        [label] => 01-02
        [count] => 577
        [customerid] => 129
    )

[1] => Array
    (
        [name] => Bookngo
        [label] => 01-02
        [count] => 2
        [customerid] => 95
    )

[2] => Array
    (
        [name] => Boutixury
        [label] => 07
        [count] => 1
        [customerid] => 14
    )

[3] => Array
    (
        [name] => Cruise Village
        [label] => 01-02
        [count] => 16
        [customerid] => 25
    )

[4] => Array
    (
        [name] => Cruise Village
        [label] => 00
        [count] => 1
        [customerid] => 25
    )

[5] => Array
    (
        [customer] => Cruise Village
        [label] => 07
        [countInbound] => 16
        [minsInbound] => 125
        [customerid] => 25
    )
  ...................
)

所需的输出应该是:

Array
(
[0] => Array
    (
        [name] => 1st Online Solutions
        [01-02] => 577
        [customerid] => 129
    )

[1] => Array
    (
        [name] => Bookngo
        [01-02] => 2
        [customerid] => 95
    )

[2] => Array
    (
        [name] => Boutixury
        [07] => 1
        [customerid] => 14
    )

[3] => Array
    (
        [name] => Cruise Village
        [07] => 16
        [00] => 1
        [01-02] => 16
        [customerid] => 25
    )
  ...................
)

怎样才能达到上述结果？

Answer 1

你可以做到这一点 -

$chartInbound = array(); 
foreach ($customers as $customer) {

  if($customer['innumber'] != null){
      if(array_key_exists([$customer['id']], $chartInbound)) {
         $chartInbound[$customer['id']][$customer['innumber'] = $customer['count'];
      } else {
         $chartInbound[$customer['id']]['name'] = $customer['name'];
         $chartInbound[$customer['id']][$customer['innumber'] = $customer['count'];
         $chartInbound[$customer['id']]['customerid'] = $customer['id'];
      }
   }
}
