使用由空格分隔的数据将变量中的数据放入<li>

问题描述：

I am trying to load data from a variable that contains information and then place them into a string to use on web page using only the space as a divider. I know I have to loop through but I cannot. Shall I perform this in PHP before or use JS to do this? Also is it possible to load up to say 3 at a time? Is it possible to do this? The string looks like this :-

$areas = "London Birmingham Leeds Glasgow Bradford Liverpool Edinburgh etc etc"

and this is how I would like to place the data :-

<h3 class="areas">London</h3>
<h3 class="areas">Birmingham</h3>
<h3 class="areas">Leeds</h3>

or something like :-

<h3 class="areas">London Birmingham, Leeds</h3>

Thanks in advance for any advice.

我正在尝试从包含信息的变量加载数据，然后将它们放入要在网页上使用的字符串中仅使用空格作为分隔符。我知道我必须循环，但我不能。我以前在PHP中执行此操作还是使用JS来执行此操作？也可以一次加载3个？是否有可能做到这一点？字符串如下所示： - p>

  $ areas =“London Birmingham Leeds Glasgow Bradford Liverpool Edinburgh等”
  code>  pre> 
 
 这就是我想要放置数据的方式： -   p> 
 
  ＆lt; h3 class =“areas”＆gt;伦敦＆lt; / h3＆gt; 
＆lt; h3 class =  “areas”＆gt; Birmingham＆lt; / h3＆gt; 
＆lt; h3 class =“areas”＆gt; Leeds＆lt; / h3＆gt; 
  code>  pre> 
 
 或类似名称： -    p> 
 
 
 ＆lt; h3 class =“areas”＆gt; London Birmingham，Leeds＆lt; / h3＆gt; 
  code>  pre> 
 
 提前致谢 任何建议。 p> 
  div>

答

You do not need any JS to do that, only the explode built-in function :

$areas_list = explode(' ', $areas);

foreach ($areas_list as $area) {
    echo '<h3 class="areas">' . $area . '</h3>';
}

答

You can simply explode() your String into an Array and loop through it :

$areas = "London Birmingham Leeds Glasgow Bradford Liverpool Edinburgh etc etc";

foreach(explode(' ',$areas) as $area){
  echo '<h3 class="areas">'.$area.'</h3>';
}
