php - 如果 php 数组包含值，则分配样式

Question

您好，我正在使用 tmdb api 并获取 Actor 电影列表 var json。如果电影是恐怖片，代码会按照我想要的方式工作，除了我会尝试将电影缩略图设置为与其他部分不同的样式。

$tmdb = $_GET['tmdb'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://api.themoviedb.org/3/person/".$tmdb."?api_key=#######");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
$person = curl_exec($ch);
curl_close($ch);
$actor= json_decode($person, true); // Decode the results into an array
$name = $actor['name'];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://api.themoviedb.org/3/discover/movie?&with_cast=".$tmdb."&vote_count.gte=5&sort_by=release_date.desc&api_key=#######");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
$personCredits = curl_exec($ch);
curl_close($ch);
$credits= json_decode($personCredits, true); // Decode the results into an array

$counter4 = 0;
$counter5 = 0;
echo "<pre>";
print_r($credits);
echo "</pre>";

$page=1;
echo "<div style='width:800px;overflow:hidden;position:absolute;ktop:1100px;left:75'>";

while ( $page <= $credits['total_pages'] ) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://api.themoviedb.org/3/discover/movie?&with_cast=".$tmdb."&vote_count.gte=5&sort_by=release_date.desc&page=".$page."&api_key=#######");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    $personCredits = curl_exec($ch);
    curl_close($ch);
    $credits= json_decode($personCredits, true); // Decode the results into an array

    $resultsCount4=(count($credits['results']))-1;
    while ( $counter4 <= $resultsCount4 ) {

        // THIS IS WHERE I NEED HELP PLEASE>>>>>
        if($credits['results'][$counter4]['genre_ids'] == 27) {
            $style="horror"; 
        } else { $style="round"; }
        ////////////////////////////////////////////////////

        echo "<div style='width:200;height:260;float:left;text-overflow:ellipsis    white-space: nowrap; 
                        width: 14em; 
                        overflow: hidden;
                        '><center><div class='".$style."'><a href=\"/?id=moviepage.php&ttno=".$credits['results'][$counter4]['id']."\"><img width=\"154\" height=\"231\"onerror=\"this.src='nocover.png'\" src='http://image.tmdb.org/t/p/w154/".$credits['results'][$counter4]['poster_path']."'></div><br>".$credits['results'][$counter4]['title']."<br>".$credits['results'][$counter4]['release_date']."</center></a></div>";
        $counter4++;
    }
    $page++;
    $counter4=0;
}

Json 数组看起来像

Answer 1

genre_ids 是一个数组(注意名字是复数，《The Whole Truth》分两个流派)，不是数字，所以

if($credits['results'][$counter4]['genre_ids'] == 27)

不会工作。使用 in_array()

if (in_array(27, $credits['results'][$counter4]['genre_ids'])
