我该如何循环获取所有日期及其时间的值？ $result['timeZone']可以正确打印出该值，但是$result['days']则不能。

 <?php 
   $result=json_decode($doctor->time_availiable,true);
   echo $result['timeZone'];

    foreach ($result['days'] as $key => $value) {
       echo $key.':'.$value;
    }

 ?>

Answer 1

在您的示例中，$value方法内部的foreach()是一个数组，无法回显。

尝试一下：

<?php 
   $result=json_decode($doctor->time_availiable,true);
   echo $result['timeZone'];

    foreach ($result['days'] as $dayFromArray) {
        foreach($dayFromArray as $dayFromObject => $hours) {
            foreach($hours as $hour) {
                echo $day.':'.$hour."\n";   
            }
            echo "\n";
        }
    }
 ?>

Answer 2

尝试下面，

$results = json_decode($doctor->time_availiable, true);

foreach ($results as $key => $result)
{

    foreach ($results['days'] as $dayName => $timeAry)
    {
        //in timeAry you will get respective day times
    }
}

Answer 3

这将使您全程工作，请注意一些json解码为对象，而不是数组

$result=json_decode($doctor->time_availiable,true);

echo $ result-> timeZone;

foreach ($result['days'] as $key => $value) {
   foreach ($value as $weekday => $hours) {
        echo $weekday;
        foreach($hours as $hour) {
            echo $hour . ', ';
        }
   }    
}

转换为php多维数组后如何遍历json对象？
