PHP配列に値が含まれている場合にスタイルを割り当て

Question

こんにちはImはtmdb apiを使用し、actorsムービーリストを取得します。var json。コードは私が離れて望む方法で動作します。映画が恐怖の場合は、映画のサムネイルを残りの部分とは異なるスタイルにしています。

$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配列が

Array 
     (

のように見え、事前

Answer 1

genre_idsでのおかげで（名前が複数であることを告知し、「真実」は、2つのジャンルである）の配列です、数字ではないので、

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

は動作しません。あなたは `$クレジット[ '結果'] [$ COUNTER4]`を繰り返し続ける必要はありませんので、in_array()

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