php数组，循环得到确切的值 [英] php array, loop to get the exact value

问题描述

我在这里有这个代码，其中 $ friends 变量是一个数组，输出如下：

  {
id：1149862205，
name：name，
first_name：first_name，
last_name：last_name，
link：https://www.facebook.com/username，
username：username，
birthday ：07/12/1990，
hometown：{
id：108618265828550，
name：name
}，
  

而 $ fbfriendlikes 变量是由id $ friends 并具有以下结构：

  {
数据：[
 {
name：Penelope-ns-test，
category：Community，
id：187099821418102，
created_time：2012-06-14T15：00：59 + 0000
}，
  

现在，我需要在 $ fbfriendlikes $中打印所有 $ friends b $ b我的c ode如下所示：

  $ friends = $ facebook-> api（'/ me / friends'）; 
 if（！empty（$ friends ['data']））{
 $ size = variable_get（'facebook_graph_pic_size_nodes'，'square'）; 
 $ protocol =（isset（$ _ SERVER ['HTTPS']）&& $ _SERVER ['HTTPS'] =='on'）？ 'https'：'http'; 
 foreach（$ friends ['data'] as $ data）{
 $ fbid = $ data ['id']; 
 $ fbfriendlikes [$ fbid] = $ facebook-> api（'/'.$ fbid。'/ likes'）; 
 $ fbname = $ data ['name']; 
 $ path = $ protocol。 '：//graph.facebook.com/'。 $ fbid。 '/ picture？type ='。 $大小; 
 $ image = theme（'image'，array（'path'=> $ path，'alt'=> $ fbname））; 
 
 if（$ fbfriendlikes [id]！= 184759054887922）{
 $ return。='< div class =fimage>'。$ image。'< / DIV>'; 
 $ link ='< a href ='。$ protocol。'：//www.facebook.com/profile.php？id ='。$ fbid。'target =_ blank>' 。$ fbname '< / A>'。 
 $ return。='< div class =flink>'。$ link。'< / div>'; 
 break; 
} 
} 
} 
  

我知道我必须在 $ fbfriendslikes 中执行foreach循环，但我似乎无法使其工作。
你能给我一个建议吗？

解决方案

你需要检查里面的循环才能得到那些

  $ return =''; 
 $ friends = $ facebook-> api（'/ me / friends'）; 
 if（！empty（$ friends ['data']））{
 $ size = variable_get（'facebook_graph_pic_size_nodes'，'square'）; 
 $ protocol =（isset（$ _ SERVER ['HTTPS']）&& $ _SERVER ['HTTPS'] =='on'）？ 'https'：'http'; 
 foreach（$ friends ['data'] as $ data）{
 $ fbid = $ data ['id']; 
 $ fbfriendlikes [$ fbid] = $ facebook-> api（'/'.$ fbid。'/ likes'）; 
 $ fbname = $ data ['name']; 
 $ path = $ protocol。 '：//graph.facebook.com/'。 $ fbid。 '/ picture？type ='。 $大小; 
 $ image = theme（'image'，array（'path'=> $ path，'alt'=> $ fbname））; 
 
 foreach（$ fbfriendlikes ['data'] as $ like）{
 $ likes = false; // set var to check for like 
 if（$ like ['id'] =='184759054887922'）{//检查他们是否喜欢
 $ likes = true; //将var设置为true，因为它们喜欢它
} 
 if（！$ likes）{//测试var查看是否为false（他们不喜欢）
 //打印出来，如果他们不喜欢它，否则不做任何
 $ return。='< div class =fimage>'。$ image。'< / div>'; 
 $ link ='< a href ='。$ protocol。'：//www.facebook.com/profile.php？id ='。$ fbid。'target =_ blank>' 。$ fbname '< / A>'。 
 $ return。='< div class =flink>'。$ link。'< / div>'; 
} 
} //继续循环
 
} 
 echo $ return; 
} 
  

I have this code right here, where the $friends variable is an array with an output like this:

{
  "id": "1149862205",
  "name": "name",
  "first_name": "first_name",
  "last_name": "last_name",
  "link": "https://www.facebook.com/username",
  "username": "username",
  "birthday": "07/12/1990",
  "hometown": {
    "id": "108618265828550",
    "name": "name"
  }, 

while $fbfriendlikes variable is generated by the id of $friends and has this structure :

{
  "data": [
    {
      "name": "Penelope-ns-test",
      "category": "Community",
      "id": "187099821418102",
      "created_time": "2012-06-14T15:00:59+0000"
    },

Now, I need to print all $friends ids which like a specific id in $fbfriendlikes My code goes like this:

$friends = $facebook->api('/me/friends');
if (!empty($friends['data'])) {
    $size = variable_get('facebook_graph_pic_size_nodes','square');
    $protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';
    foreach ($friends['data'] as $data) {
        $fbid = $data['id'];
        $fbfriendlikes[$fbid]=$facebook->api('/'.$fbid.'/likes'); 
        $fbname = $data['name'];
        $path = $protocol . '://graph.facebook.com/' . $fbid . '/picture?type=' . $size;
        $image = theme('image', array('path' => $path, 'alt' => $fbname));

        if ($fbfriendlikes["id"] != 184759054887922) {
            $return .= '<div class="fimage">'.$image.'</div>';
            $link = '<a href="'.$protocol . '://www.facebook.com/profile.php?id='.$fbid.'" target="_blank">'.$fbname.'</a>';    
            $return .= '<div class="flink">'.$link.'</div>';
            break;
        }
    }
}

I know I have to do a foreach loop in $fbfriendslikes but I can't seem to make it work. Can you please give me an advice?

解决方案

You need to check inside you loop to get the ones that don't like.

$return = '';
$friends = $facebook->api('/me/friends');
if (!empty($friends['data'])) {
    $size = variable_get('facebook_graph_pic_size_nodes','square');
    $protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';
    foreach ($friends['data'] as $data) {
        $fbid = $data['id'];
        $fbfriendlikes[$fbid]=$facebook->api('/'.$fbid.'/likes'); 
        $fbname = $data['name'];
        $path = $protocol . '://graph.facebook.com/' . $fbid . '/picture?type=' . $size;
        $image = theme('image', array('path' => $path, 'alt' => $fbname));

        foreach($fbfriendlikes['data'] as $like) {
            $likes = false; // set var to check for like
            if($like['id'] == '184759054887922') { // check if they liked it
                $likes = true; // set var to true because they liked it
            }
            if (!$likes) { // test var to see if false (they did not like)
                // print this if they did NOT like it, otherwise do nothing
                $return .= '<div class="fimage">'.$image.'</div>';
                $link = '<a href="'.$protocol . '://www.facebook.com/profile.php?id='.$fbid.'" target="_blank">'.$fbname.'</a>';    
                $return .= '<div class="flink">'.$link.'</div>';
            }
        }// go on to next in loop

    }
    echo $return;
}
