為 PHP 返回多維數組值

Question

我要從提供者返回數據，提供的數組如下所示：

Array
(
    [result] => Array
        (
            [0] => Array
                (
                    [problem_id.u_root_cause] => 
                    [number] => INC0000001
                    [short_description] => Unable to print
                    [u_alert_check] => 
                    [u_business_service] => Array
                        (
                            [display_value] => Printer
                            [link] => https://redacted/37bc8af837c3820ca7e3b15ec3990e1c
                        )

                    [assignment_group] => Array
                        (
                            [display_value] => Printer Support
                            [link] => https://redacted/b699595c37dac200a7e3b15ec3990eb1
                        )

                    [u_service_impact_duration] => 57 Minutes
                    [u_summary_notes] => Changed USB cable 
                    [u_environment] => Production (PD)
                    [problem_id] => 
                    [priority] => 3 - P3
                    [u_business_services_impacted] => 
                )

現在，我可以像這樣返回大部分數據，

foreach($data['result'] as $line){
   echo $line['number'];
   echo '<br>';
   echo $line['short_description'];
}

以上從數組中返回number和short_description 。

我遇到的麻煩是如何在同一行中返回u_business_service ？

要訪問多維數組，您可以使用：

echo $line['u_business_service']['display_value'];
echo $line['u_business_service']['link'];
