我目前正在开发一个为多个维度创建数组的项目。 print_r()会导致:
Array (
[campaigns] => Array (
[0] => Array (
[CampaignId] => 1
[DID] => 2394434444
[FWDDID] => 3214822821
[ProductId] => 1
[CampaignName] => Fort Myers Bus #1
[ProductName] => CallTrack - Sharktek
[Active] => 1 [CompanyId] => 1 )
[1] => Array (
[CampaignId] => 4
[DID] => 2394434445
[FWDDID] => 3214822821
[ProductId] => 1
[CampaignName] => Cape Coral Billboard #2
[ProductName] => CallTrack - Sharktek
[Active] => 1 [CompanyId] => 1 )
[2] => Array (
[CampaignId] => 5
[DID] => 2392146000
[FWDDID] => 3214822821
[ProductId] => 1
[CampaignName] => Test Campaign
[ProductName] => CallTrack - Sharktek
[Active] => 1
[CompanyId] => 1 )
)
)
我正在尝试创建一个foreach循环,它选择所有的CampaignIds并在每个循环中使用它们,遗憾的是,我无法这样做。
因为我正在使用CodeIgniter,所以我无法简单地在控制器中回显结果,而是我必须将我想要的值传递给另一个数组以发送到视图
感谢您的时间和努力,任何帮助将不胜感激!

如果您只想稍后将所有CampaignId传递给foreach
并且您有PHP> = 5.5.0,那么请使用array_column
:
$ids = array_column($array, 'CampaignId');
如果PHP< 5.5.0然后foreach
超过$array['campaigns']
。
foreach($array['campaigns'] as $campaign) {
$ids[] = $campaign['CampaignId'];
}
