使用 PHP 访问 Google 日历 JSON

Question

我从 google api 得到假期很累，这是我的 php 代码。 return json 来自 google 的数据是正确的

 $calendar_id = urlencode('japanese.ja@holiday.calendar.google.com');
        // 取得期間
        $start  = date("Y-01-01\T00:00:00\Z");
        $end = date("Y-12-31\T00:00:00\Z");
        $url = 'https://www.googleapis.com/calendar/v3/calendars/en.japanese%23holiday%40group.v.calendar.google.com/events?key=apikeyhere';
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        $result = curl_exec($ch);
        curl_close($ch);
        if (!empty($result)) {
            $json = json_decode($result);

                foreach($json->items as $mydata)

    {       
         foreach($mydata as $values)
         {
              echo $values->summary . "\n";
              echo $values->start. "\n";
         }

    }

我需要总结一下并从该数据开始，但上面的代码什么也没显示，我厌倦了使用各种 foreach 但没有用。有人可以帮助我得到夏天并从中开始吗，谢谢

这是 google 压延机 v3

的部分输出 json

**我从具有工作 json 部分

的 js 代码转换了此代码

数据变量是google输出的json，我只需要将这部分转换成php**

for (item in data.items) {
        $("#output").append(
          "<hr><h3>" + data.items[item].summary + "<h3>" +
          "<h4>" + data.items[item].start.date + "<h4>"
        );
      }

Answer 1

你的代码几乎是正确的，你只是有一个 foreach 循环太多了，一旦你迭代了项目你可以直接访问它们的属性，不需要循环它们。

// Check if we got some results
if (!empty($result)) {

    // Parse the results
    $json = json_decode($result);

    // Iterate over the item property of the resultset
    foreach($json->items as $item) {

        // Each item is an object, 
        // 'summary' and 'start' are properties of 'item'
        // 'date' is a property of 'start'
        echo '<hr><h3>' . $item->summary . '</h3>';

        echo '<h4>' . $item->start->date . '</h4>';

    }
}

我把$myData的名字改成了$item，我觉得这样代码更容易理解，如果你想保留名字[=14=，可以随时更新答案].
