JSON陣列被重複索引

Question

這是我的代碼：

if ($API->connect("192.168.81.130", "admin", "")) { 
    $API->write('/ip/route/print', false); 
    $API->write('=.proplist=.id', false); 
    $API->write('=.proplist=dst-address', false); 
    $API->write('=.proplist=pref-src', false); 
    $API->write('=.proplist=gateway'); 
    $result = $API->read(); 
    $API->disconnect(); 

    foreach ($result as $route){ 
     $response['id'] = $route['.id']; 
     $response['dst-address'] = $route['dst-address']; 
     if (isset($route['pref-src'])) { 
      $response['pref-src'] = $route['pref-src']; 
     } else { 
      $response['pref-src'] = ""; 
     } 
     $response['gateway'] = $route['gateway']; 
     $array[] = $response; 
     echo json_encode($array); 
    } 
} 

並且輸出是：

[{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"}][{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"},{"id":"*420639B3","dst-address":"192.168.81.0\/24","pref-src":"192.168.81.130","gateway":"ether1"}] 

結果爲 「[{」 ID 「：」 * 2" ，「DST-地址「：」0.0.0.0/0「，」pref-src「：」「，」gateway「：」192.168.1.1「}]」顯示兩次。

我想出來把這樣的：

> [{"id":"*2","dst-address":"0.0.0.0\/0","pref-src":"","gateway":"192.168.1.1"},{"id":"*420639B3","dst-address":"192.168.81.0\/24","pref-src":"192.168.81.130","gateway":"ether1"}]. 

誰能幫助我？

你需要每輪循環，否則你每次都只是增加了它，因此重複

您還需要JSON字符串的回聲移動到外循環來初始化數組

foreach ($result as $route){ 
    $response = array(); 

    $response['id'] = $route['.id']; 
    $response['dst-address'] = $route['dst-address']; 
    if (isset($route['pref-src'])) { 
     $response['pref-src'] = $route['pref-src']; 
    } else { 
     $response['pref-src'] = ""; 
    } 
    $response['gateway'] = $route['gateway']; 
    $array[] = $response; 

} 
echo json_encode($array);
