如何在php中添加来自序列化字符串的额外字母？

Question

我正在处理 php 中的序列化字符串，我想在它未序列化时添加额外的字母。

序列化字符串的sn-ps为：

a: 7: {
    s: 3: "mon";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "tue";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "wed";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "thu";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "fri";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "sat";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "sun";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
}

为了使上述序列化字符串反序列化，我使用的 php 代码是：

<?php 
   $serialized = '';
   for ($i = 0; $i < count($data['item']->logistic_out); $i++) {
   if(strcmp($data['item']->logistic_out[$i]->logistics_type, "location_pickup") == 0)
   {
   $serialized .= strtolower($data['item']->logistic_out[$i]->logistics_times);
   }
   }
   if($serialized != '')
   {
   /*
   echo '<span class="font-weight-bold how-can-this-text">' . "how can this item be received" . '</span>';
   echo "<br>"; 
   echo "<br>"; 
   echo '<span class="font-weight-bold mb-3 ml-3">' . "pickup from item's location <br/>" . '</span>';
   echo "<br>";
   echo "<br>";  */
   $unserialized = unserialize( $serialized );

   foreach($unserialized as $key=>$value)
   {
   echo $key.":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;".$value['start']."&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;".$value['end']."<br/> <br/>";
   }
   }
   else
   {
       echo "<p style=\"font-style: italic;\">No information available</p>";
   }
   ?>

问题陈述：

上述代码中的echo语句正在生成以下o/p。我想知道我应该在上面的 echo 语句中进行哪些更改，以便 o/ps 具有星期一星期二星期三星期四星期五星期六星期日

Answer 1

您可以转换为时间戳，然后提取星期几的完整文本表示：

echo date('l', strtotime($key));

要将时间从 24 小时更改为 12 小时，请执行相同的操作：

echo date('g', strtotime($value['end']));

请参阅PHP - date 了解所有格式。

Answer 2

更新了我的答案。请检查

echo date('l', strtotime($key)).":&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;".$value['start']."&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;".$value['end']."<br/> <br/>";
