Php 为一周中的每一天设置打开和关闭时间

我有以下代码来检查开放和关闭时间，它工作正常

// Set open and closing time for each day of the week
if ($weekday == "Monday") {
$open_from = "17:00";
$open_to = "21:45";
}

我想要实现的是从xml文件中获得几个小时的时间，但它不起作用

// Set open and closing time for each day of the week
if ($weekday == "Monday") {
$open_from = "<?php echo $mondayopen->nodeValue  ?>";
$open_to = "<?php echo $mondayclosed->nodeValue  ?>";
}

//为一周中的每一天设置打开和关闭时间
如果（$weekday==“周一”）{
$open_from=“”；
$open_to=“”；
}

我在另一个参数中使用了这段代码，效果很好

<tr><td class="text-left">Monday</td>
<td class="text-right"><?php echo $mondayopen->nodeValue  ?> - <?php echo $mondayclosed->nodeValue  ?></td>
</tr>

星期一

您可以直接访问

$modayopen

和

$mondayclose

，无需回复：

// Set open and closing time for each day of the week
if ($weekday == "Monday") {
  $open_from = $mondayopen->nodeValue;
  $open_to = $mondayclosed->nodeValue;
}

您的php代码应该是这样的

 if ($weekday == "Monday") {
    $open_from = $mondayopen->nodeValue;
    $open_to = $mondayclosed->nodeValue;
    }
//(or)
    if ($weekday == "Monday") {
    $open_from = '"'.$mondayopen->nodeValue.'"';
    $open_to = '"'.$mondayclosed->nodeValue.'"';
    }
