Answer 1

从逻辑上思考你打开<ul>和<li>的位置与关闭它们的位置（即它应该在循环中还是在外面，显然它不应该被打开以便打开并且关闭，无论是打开还是关闭都进入循环或外部，而不是一进一出）并在结束时修复<?ul>的拼写错误。

并且不要像<ul><li><div></li></ul></div>那样。您需要按照打开它们的顺序关闭标记。即<ul><li><div></div></li></ul>

我想你想要做的事情：

<div id="movies">
<ul>
<?php 
foreach($movieTitle as $movie)
{
    echo '<li>';
    echo '<img src="' . $movie->image . '" />';
    echo '<div class="cFFF">' . $movie->movie_name . '</div>';
    echo '<div class="s11 c999">Rating: ' . round($movie->rating) . '</div>';
    echo '</li>';
}
?>
</ul>
</div>

Answer 2

你也可以通过使用下面的php语句打印$ movieTitle数组的输出来检查：

echo count（$ movieTitle）;

确保您的MySQL JOIN返回正确的结果。

PHP <ul> <li>数据库</li> </ul>
