Question

HTTP Rest API向我显示上面的值：

        id  514
        filial  5
        name    "COD. 514 20 Mb RES. TRL"
        nome_amigavel   "20 Mb"
        mensalidade "89.90"
        desconto    "0.00"
        ativo   1
        tipo    1
        instalacao  "300.00"
        bnd_up  2000
        bnd_down    20000
        1   
        id  422
        filial  4
        name    "COD. 069 30 Mb TRANSPORTE"
        nome_amigavel   "30 Mb"
        mensalidade "1500.00"
        desconto    "0.00"
        ativo   1
        tipo    3

        bnd_up  0
        bnd_down    30000
        2

我如何＆＃34;打印＆＃34;或者＆＃34; Echo＆＃34; PHP文件中的特定值或单个值????

                                  <?php



          $curl = curl_init();
          curl_setopt_array($curl, array(
            CURLOPT_URL => "https://services.west.net.br/rest/server.php/planos",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "GET",
            CURLOPT_HTTPHEADER => array(
                          "authorization: Basic YXaBepOmsadsahpaacGVwwaybassdwsadsadsawd3BpYSBw0cmddF2YWdaalbSBiaXBdlbmFkbw==",
                          "cache-control: no-cache",
                          "content-type: application/json",
                      ),
                  ));
          $response = curl_exec($curl);
          $err = curl_error($curl);

          curl_close($curl);

          if ($err) {
            echo "cURL Error #:" . $err;
          } else {
            echo $response;
          }
          ?>

我试试这个，但没有成功，我在休息api的新手，并尝试从网上的一些例子，请帮助一些！

使用以下代码

$curl_response = curl_exec($curl); //<!---- $curl_responce instead of $output
if ($curl_response === false) {
    $info = curl_getinfo($curl);
    curl_close($curl);
    die('error occured during curl exec. Additioanl info: ' . 
    var_export($info)); //<!--- this is pointless IMO
}
curl_close($curl);
$decoded = json_decode($curl_response);  ///<!--- set to results to $decoded, also no second value ie. "json_decode($curl_response, 1);"

if (isset($decoded->response->status) && $decoded->response->status == 'ERROR') {
    die('error occured: ' . $decoded->response->errormessage);
}
echo 'response ok!';
var_export($decoded->response);

//==================================//
// looks like someone just dropped the code below
// this line in. ha ha.

$result = json_decode($output, 1);  //<!--- output does not exist, but this is already done above. so use $decoded instead of $output.
 // check if an id came back
 if (!empty($result['id'])) {
  $deal_id = $result['id'];
  return $deal_id;
 } else {
  return false;
 }

echo $deal_id;

永远不会设置变量$output，而是使用$decoded。这是因为$result也不存在，而是在上面的代码中$curl_response。感觉你已经解码了，不需要再解码了。

那就是说，在json_decode那里，第二个参数没有设置为true，在这种情况下，你得到一个对象而不是你想象的数组。

http://php.net/manual/en/function.json-decode.php

混合json_decode（字符串$ json [，bool $ assoc = false [，int $ depth = 512 [，int $ options = 0]]]）

<强> ASSOC   如果为TRUE，则返回的对象将转换为关联数组。

第二个选项是JSON_OBJECT_AS_ARRAY，其效果与将assoc设置为TRUE相同。

要解决您遇到问题的部分应该能够用=====替换// check if an id came back if (!empty($output->id)) { $deal_id = $output->id; return $deal_id; } else { return false; // should echo something instead of returning. } echo $deal_id;下的内容。

 echo 'response ok!';
 var_export($decoded->response);

同样要删除其他输出，请注释这两行。
