)
)

function array2ul($array) {
$out = "<ul>";
foreach($array as $key => $elem){
if(!is_array($elem)){
$out .= "<li><span>$key:[$elem]</span></li>";
}
else $out .= "<li><span>$key</span>".array2ul($elem)."</li>";
}
$out .= "</ul>";
return $out;
}

Here's a much more maintainable way to do it than to echo html...
这是一种比 echo html 更易于维护的方法......
<ul>
<?php foreach( $array as $city => $hotels ): ?>
<li><?= $city ?>
<ul>
<?php foreach( $hotels as $hotel ): ?>
<li><?= $hotel ?></li>
<?php endforeach; ?>
</ul>
</li>
<?php endforeach; ?>
</ul>
Here's another way using h2s for the cities and not nested lists
这是对城市使用 h2s 而不是嵌套列表的另一种方法
<?php foreach( $array as $city => $hotels ): ?>
<h2><?= $city ?></h2>
<ul>
<?php foreach( $hotels as $hotel ): ?>
<li><?= $hotel ?></li>
<?php endforeach; ?>
</ul>
<?php endforeach; ?>
The outputted html isn't in the prettiest format but you can fix that. It's all about whether you want pretty html or easier to read code. I'm all for easier to read code =)
输出的 html 不是最漂亮的格式，但您可以修复它。这完全取决于您是否想要漂亮的 html 或更易于阅读的代码。我都是为了更容易阅读代码 =)

Refactored acmol's funciton
重构acmol的函数
/**
* Converts a multi-level array to UL list.
*/
function array2ul($array) {
$output = '<ul>';
foreach ($array as $key => $value) {
$function = is_array($value) ? __FUNCTION__ : 'htmlspecialchars';
$output .= '<li><b>' . $key . ':</b> <i>' . $function($value) . '</i></li>';
}
return $output . '</ul>';
}

Assume your data is in $array.
假设您的数据在 $array 中。
echo '<ul>';
foreach ($array as $city => $hotels)
{
echo "<li>$city</li>\n<ul>\n";
foreach ($hotels as $hotel)
{
echo " <li>$hotel</li>\n";
}
echo "</ul>\n\n";
}
echo '</ul>';
Haven't tested it, but I'm pretty sure it's right.
还没有测试过，但我很确定它是正确的。
