如何同时显示数组键和值?

html php

Sebastian · 技术社区 · 7 年前

我想为我的网站构建一个动态生成的开放时间列表,以突出显示当前的一天。

在第一步中,我想通过PHP生成HTML列表。不幸的是,这行不通。我的代码:

<ul>
    <?php
        /* Sunday = 0 */
        $daynumber_of_week = date('w', strtotime('Sunday'));

        /* Define Opening Hours */
        $openingHours = array(
            "sunday" => array("Closed"),
            "monday" => array("Closed"),
            "tuesday" => array("8.30 am - 3.00 pm"),
            "wednesday" => array("8.30 am - 1.30 pm", "2.00 pm - 7.00 pm"),
            "thursday" => array("8.30 am - 0.30 pm", "2.00 pm - 7.00 pm"),
            "friday" => array("8.30 am - 0.30 pm", "1.00 pm - 6.00 pm"),
            "saturday" => array("8.30 am - 2.00 pm")
        );

        /* Create Opening Hours */
        for ($x = 0; $x < count($openingHours); $x++)
        {
            echo '<li class="list-unstyled-item d-flex">' . $openingHours[$x] . '<span class="ml-auto">' . $openingHours[$x][0] . '</span></li>';

            if (isset($openingHours[$x][1]))
            {
                echo '<li class="list-unstyled-item d-flex"><span class="ml-auto">' . $openingHours[$x][1] . '</span></li>';
            }
        }
    ?>
</ul>

我想在回音行中显示以下内容,但它不显示任何内容:

$openingHours[$x] -> e.g. wednesday
$openingHours[$x][0] -> first Value of wednesday e.g. "8.30 am - 1.30 pm"
$openingHours[$x][1] -> second Value of wednesday e.g. "2.00 pm - 7.00 pm"

这正变得不必要的复杂。使用扩展 foreach .

$daynumber_of_week = date('w', strtotime('Sunday'));

/* Define Opening Hours */
$openingHours = array(
    "sunday" => array("Closed"),
    "monday" => array("Closed"),
    "tuesday" => array("8.30 am - 3.00 pm"),
    "wednesday" => array("8.30 am - 1.30 pm", "2.00 pm - 7.00 pm"),
    "thursday" => array("8.30 am - 0.30 pm", "2.00 pm - 7.00 pm"),
    "friday" => array("8.30 am - 0.30 pm", "1.00 pm - 6.00 pm"),
    "saturday" => array("8.30 am - 2.00 pm")
);

foreach ($openingHours as $key => $value) {
    echo '<li class="list-unstyled-item d-flex">' . $key . '<span class="ml-auto">' . $value[0] . '</span></li>';

    if (isset($value[1]))
    {
        echo '<li class="list-unstyled-item d-flex"><span class="ml-auto">' . $value[1] . '</span></li>';
    }
}

注: [] 声明数组而不是 array() 从php 5.4开始。

$openHoursHtml = '<ul>';

foreach($openingHours as $day => $openHoursArr)
{
    $openHoursHtml .= "<li><span class='day'>" . $day . "</span>";
    $openHoursHtml .= "<span class='hours'>" . implode(",", $openHoursArr) . "</span>";
    $openHoursHtml .= '</li>';
}

$openHoursHtml .= '</ul>';
echo $openHoursHtml;
