创建PHP阵列

我想在PHP中创建一个数组，但我不知道我做错了什么。下面似乎并不奏效。当我创建一个我可以访问它的变量时，json是绝对可用的。然而，该阵列似乎并没有工作。创建PHP阵列

for ($x=0; $x<=7; $x++){ 

$forecasetp[] = array(); 

    $forecastp[x] = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[x]->{'title'};

为了简化我想更换一个循环被解析

$forecastp2 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[1]->{'title'}; 
    $forecastt2 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[1]->{'fcttext'}; 

    $forecastp3 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[2]->{'title'}; 
    $forecastt3 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[2]->{'fcttext'}; 

    $forecastp4 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[3]->{'title'}; 
    $forecastt4 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[3]->{'fcttext'}; 

    $forecastp5 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[4]->{'title'}; 
      $forecastt5 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[4]->{'fcttext'}; 

     $forecastp6 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[5]->{'title'}; 
     $forecastt6 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[5]->{'fcttext'}; 

     $forecastp7 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[6]->{'title'}; 
     $forecastt7 = $parsed_json->{'forecast'}->{'txt_forecast'}->{'forecastday'}[6]->{'fcttext'};

JSON如下：

第一次发布了错误的json。用正确的json更新 – user2941841 2014-09-21 23:36:51

尝试以下操作：

$forecasetp[] = array(); 
foreach ($parsed_json->forecast->txt_forecast->forecastday as $day) 
{ 
    $forecastp[] = $day->title; 
}

这将f。添加title f作为$forecastp阵列的一个元素的值;你可以访问它作为$forecastp[0]。

注：

  • 如果你只是想推的元素，没有他们设置一个特定的索引，使用$forecastp[]。
  • PHP数组从0开始计数。

编辑：现在我明白你想要做什么。发布更新。

是的，我从0开始。试图让它工作。更新的代码示例。仍然不能让它工作。 – user2941841 2014-09-21 23:22:42

在根JSON对象上使用'foreach'而不是'for'。您不需要设置索引，只需使用我的示例中发布的“推送”即可。 – lxg 2014-09-21 23:24:14

@ user2941841：啊，我想你想迭代'$ parsed_json-> forecast-> txt_forecast-> forecastday'列表。代码已更新。 – lxg 2014-09-21 23:26:59

由Ixg的答案可能会工作，但只有$ json_string是一个对象。

您也可以尝试

$forecastp[] = $parsed_json['forecast10day']['forecast']['txt_forecast']['forecastday'][0]->title;

的基础是多数民众赞成 - >_是对象和[ '____']是数组。

谢谢。我现在得到这个虽然：致命错误：不能使用stdClass类型的对象作为数组 – user2941841 2014-09-21 23:25:57

你可以做print_r（$ parsed_json）并将结果复制到这里吗？ – 2014-09-21 23:27:38

json正在解析发布 – user2941841 2014-09-21 23:33:22
