JSON數組值到變量（Linkedin PHP庫）

我是API和JSON的noob，希望對以下任何幫助。我正在使用PHP Linkedin Library來運行People Queries。JSON數組值到變量（Linkedin PHP庫）

下面是相關代碼：

<?php 
      $OBJ_linkedin->setResponseFormat(LINKEDIN::_RESPONSE_JSON); 
      $keywords = (isset($_GET['keywords'])) ? $_GET['keywords'] : "Marketing"; 
      ?> 
      <form action="<?php echo $_SERVER['PHP_SELF'];?>#peopleSearch" method="get"> 
       Search by Keywords: <input type="text" value="<?php echo $keywords?>" name="keywords" /><input type="submit" value="Search" /> 
      </form> 
      <?php 
      $query = '?sort=distance&current-company=true&keywords='.$keywords; 
      $response = $OBJ_linkedin->searchPeople($query); 

      if($response['success'] === TRUE) { 


echo "<pre>" . print_r($response['linkedin'], TRUE) . "</pre>"; 
      } else { 
       // request failed 
       echo "Error retrieving people search results:<br /><br />RESPONSE:<br /><br /><pre>" . print_r($response) . "</pre>";     
      } 
      } else { 
      // user isn't connected 
      ?>

下面是輸出的摘錄，我得到

{"people": { 
    "_count": 10, 
    "_start": 0, 
    "_total": 11, 
    "values": [ 
    { 
     "firstName": "Peter", 
     "headline": "Frontend Engineer at Lot18", 
     "id": "kYZ3B2hHYH", 
     "lastName": "Welch", 
     "pictureUrl": "http://m.c.lnkd.licdn.com/mpr/mprx/0_e0hbvSXvhiSoTO2PERiqvfLV850d342PoOq4vakwx8IJOyR1XJrwRmr5mIx9C0DxWpGMsWVjBZEQ", 
     "relationToViewer": {"distance": 3} 
    }, 

    ] 
}}

我想拍攝像「名字」和「pictureUrl」到變量的字段我可以在別處使用。例如。

<img src="<?php echo $picture-url; ?>" />

我該怎麼做呢？我花了數天的時間尋找/試圖弄清楚這一點，仍然沒有運氣。任何幫助深表感謝！

響應格式是編碼爲一個字符串

$response['linkedin']

取回對象，使用JSON對象：

$responseObject = json_decode($response['linkedin']);

然後你就可以像這樣訪問

$responseObject->values[0]->pictureUrl

變量

我在上面的「if」語句中放置了該代碼，但我沒有得到任何結果。這裏是[pastebin]（http://pastebin.com/Fdkjvjtm）'if（$ response ['success'] === TRUE）{ // echo「

" . print_r($response['linkedin'], TRUE) . "

」; $ responseObject = json_decode（$ response ['linkedin']）; echo $ responseObject-> values [0] - > pictureUrl; }' – ace973
