You can use implode()and print the list:
您可以使用implode()和打印列表：
echo '<ul>';
echo '<li>' . implode( '</li><li>', $people) . '</li>';
echo '</ul>';
Note this would print an empty <li>for an empty list - You can add a check in to make sure the array isn't empty before producing any output (which you would need for any loop so you don't print an empty <ul></ul>).
请注意，这将为<li>空列表打印一个空- 您可以添加一个签入以确保在生成任何输出之前数组不为空（任何循环都需要它，因此您不会打印空<ul></ul>）。
if( count( $people) > 0) {
echo '<ul>';
echo '<li>' . implode( '</li><li>', $people) . '</li>';
echo '</ul>';
}

You need to use loop to output array data as text.
您需要使用循环将数组数据输出为文本。
There are multiple loops in PHP:
PHP 中有多个循环：
FOR
为了
For will iterate $i (can be diferent variable and different change than iteration) and will end when the condition is not true anymore.
For 将迭代 $i（可以是与迭代不同的变量和不同的变化），并在条件不再为真时结束。
$people = array('Joe','Jane','Mike');
for($i=0; $i<count($people); $i++) { //end when $i is larger than amount of people
echo " <li>{$people[$i]}</li>\n";
}
FOREACH
FOREACH
Very useful for unordered arrays - this loop will give you all values in the array as variable you want:
对于无序数组非常有用 - 这个循环会给你数组中的所有值作为你想要的变量：
$people = array('Joe','Jane','Mike');
foreach($people as $human) { //end when $i is larger than amount of people
echo " <li>$human</li>\n";
}
WHILE
尽管
Like FOR, loops while condition is met.
与 FOR 一样，满足条件时循环。

<?php
echo "<ul>";
foreach(array("test", "test2", "test3") as $string)) {
echo "<li>".$string."</li>"
}
echo "<ul>";
?>
