adding spaces between variables

本文关键字：空格添加之间变量 | 更新日期: 2023-09-27

我正在为类做一个项目，我需要简单地在城市国家和zip变量之间放置一个空格。请帮忙！谢谢！

代码如下所示：

echo "<p>";
echo $weather['current_observation']['display_location']['city']; 
echo $weather['current_observation']['display_location']['state']; 
echo $weather['current_observation']['display_location']['country']; 
echo $weather['current_observation']['display_location']['zip']; 
echo "</p><p>";
echo $weather['current_observation']['observation_time_rfc822'];
echo "</p><p>";
echo $weather['current_observation']['weather'];
echo "</p><p>";
echo $weather['current_observation']['temperature_string'];
echo "</p><p>";
echo $weather['current_observation']['wind_string'];
echo "</p>";

在

要添加空格的任何回声线之后回显echo '&nbsp';。

或者如表彰中所述：

"不需要不间断的空间。定期echo " ";就可以了。– ceejayoz 五月 9 '12 在 16：01">

怎么样

echo $weather['current_observation']['display_location']['city']; 
echo ' ';
echo $weather['current_observation']['display_location']['state'];

您可以使用 . 添加到字符串的末尾

所以"foo" . "bar"回报"foobar"

我会写

echo $weather['current_observation']['display_location']['city'] . ' '; 
echo $weather['current_observation']['display_location']['state'] . ' ';

您可以通过这种方式添加空格

echo $weather['current_observation']['display_location']['city'] . " ";

最简单的：

echo " ";

如果这不起作用，那么您已经遗漏了重要的细节。

对于正常空间，请执行。

 echo $weather['current_observation']['display_location']['city'] . " ";
 echo $weather['current_observation']['display_location']['state'] . " ";
 echo $weather['current_observation']['display_location']['country'] . " ";
 echo $weather['current_observation']['display_location']['zip'] . " ";

或者对于 HTML 间距做。

 echo $weather['current_observation']['display_location']['city'] . "&nbsp;";
 echo $weather['current_observation']['display_location']['state'] . "&nbsp;";
 echo $weather['current_observation']['display_location']['country'] . "&nbsp;";
 echo $weather['current_observation']['display_location']['zip'] . "&nbsp;";
