如何創建，如果在陣列

Question

foreach($top_9_friends as $key => $user) 
{ 

array_push($scores, array( 

    "id" => key($friends_rank_data), 
    "likes" => $user['likes'], 
    "comments" => $user['comments'], 
    "posts" => $user['posts'], 
    if(1 == 1) { 
     $url = 'https://graph.facebook.com/' . key($friends_rank_data) . '/?fields=gender&access_token=' . $access_token ; 
     $contents = file_get_contents($url); 
if($contents) 
{ 
    $dataa = json_decode($contents, true); 
} 
    "sex" => $dataa['data']['0']['gender'],  
    } 
) 

); 
} 

誰能幫我怎麼寫正確的代碼， 我哪裏錯了 如何輸入正確的日期

Answer 1

不知道你試圖嘗試什麼，但只是分開你如何構建陣列。

也有沒有需要如果（1 == 1）{...}，這只是意味着你總是這樣做，爲什麼要麻煩？

foreach ($top_9_friends as $key => $user) { 

    // create array 
    $arr = array(
     "id" => key($friends_rank_data), 
     "likes" => $user['likes'], 
     "comments" => $user['comments'], 
     "posts" => $user['posts'] 
    ); 

    $url = 'https://graph.facebook.com/' . key($friends_rank_data) . '/?fields=gender&access_token=' . $access_token; 
    $contents = file_get_contents($url); 
    if ($contents) { 
     $dataa = json_decode($contents, true); 

     // add this array key inside the if statement 
     $arr["sex"] = $dataa['data']['0']['gender']; 
    } 
    array_push($scores, $arr); 
} 

Answer 2

執行，如果前陣：

foreach($top_9_friends as $key => $user) 
{ 

    if(1 == 1) { 
     $url = 'https://graph.facebook.com/' . key($friends_rank_data) . '/?fields=gender&access_token=' . $access_token ; 
     $contents = file_get_contents($url); 
     if($contents) 
     { 
      $dataa = json_decode($contents, true); 
     } 
    } 

    array_push($scores, array( 
     "id" => key($friends_rank_data), 
     "likes" => $user['likes'], 
     "comments" => $user['comments'], 
     "posts" => $user['posts'], 
     "sex" => $dataa['data']['0']['gender'],  
    ); 
}

嘗試這樣的事情。爲每個新項目創建一個數組，並首先設置您知道的值。然後，您可以根據您的if聲明有條件地爲其添加值。然後，一旦數組項目被構建，就將其粘貼到scores陣列上。

<?php 

foreach($top_9_friends as $key => $user){ 

    //Temporary Array with entity proprties 
    $new_array_item = array( 
     "id" => key($friends_rank_data), 
     "likes" => $user['likes'], 
     "comments" => $user['comments'], 
     "posts" => $user['posts'] 
    ); 

    //Conditionally Add values based on IF logic 
    if(1 == 1) { 
     $new_array_item['url'] = 'https://graph.facebook.com/'.key($friends_rank_data).'/?fields=gender&access_token='.$access_token ; 

     $contents = file_get_contents($new_array_item['url']); 
     if($contents) { 
      $dataa = json_decode($contents, true); 
      $new_array_item['sex'] = $dataa['data']['0']['gender']; 
     } 
    } 
    //Tack Temporary Array Item onto $scores 
    $scores[]=$new_array_item; 
} 

?>
