we need to list an array sorting by an object value.
我们需要列出一个按对象值排序的数组。
We have a list of films, sorted by alphabetical order, but we want to sort by genres.
我们有一个电影列表,按字母顺序排序,但我们想按类型排序。
here is the code listing in alphabetical order.
这是按字母顺序排列的代码。
<?php
foreach ($films as $film_id => $film) {
echo "<ul>";
echo '<li id="film_thumb">';
echo '<a href="watch.php?id=' . $film_id . '" alt="ID">';
echo '<img class="thumb_res" src=" ' . $film["thumb"] . '" alt="' . $film["name"] . '">' ;
echo '</a>';
echo '</li>';
echo "</ul>";
} ?>
the function listing in alphabetical order is in the array file
按字母顺序排列的函数列表位于数组文件中
sort($films, SORT_FLAG_CASE);
Here is the array
这是阵列
$films = array ();
$films[1] = array(
"name" => "21 Jump Street",
"year" => "2012",
"genre" => "Commedia",
"path" => "media/01.mp4",
"thumb"=> "media/thumb/01.png",
);
now, we need to create a page that list these items ( film thumb ) in categories, so if i click on genre "Action", the page must to show only selected film genre, and not the others.
现在,我们需要创建一个页面,列出这些项目(电影拇指)的类别,所以如果我点击类型“动作”,页面必须只显示选定的电影类型,而不是其他。
Many thanks, Andrea

You can sort your array by genre with usort()
:
您可以使用usort()按类型对数组进行排序:
usort($films, function($a, $b){
return strcasecmp($a['genre'], $b['genre']);
});
If you want to get films from the selected genre, you can use array_filter()
:
如果您想从所选类型中获取电影,可以使用array_filter():
$films = array_filter($films, function($film){
return $film['genre'] == 'Commedia';
});
