Question

我有多个ID（0,1,2）。如何从以下数组中获取相应ID的城市名称？

这是一个示例数组：

$cities_array = array (
  0 => 
  array (
    'city' => 'Sant JuliÃ  de LÃ²ria',
    'region' => '06',
    'country' => 'AD',
    'latitude' => '42.46372',
    'longitude' => '1.49129',
  ),
  1 => 
  array (
    'city' => 'Pas de la Casa',
    'region' => '03',
    'country' => 'AD',
    'latitude' => '42.54277',
    'longitude' => '1.73361',
  ),
  2 => 
  array (
    'city' => 'Ordino',
    'region' => '05',
    'country' => 'AD',
    'latitude' => '42.55623',
    'longitude' => '1.53319',
  )
);

Answer 1

所以你需要使用以下代码访问php关联数组

 foreach($cities_array as $key => $value)
{
    echo $value['city'].' '.$value['region'].' '.$value['country'].' '.$value['latitude'].' '.$value['longitude']."<br>";
}

如果您没有在浏览器中显示，请使用以下代码

foreach($cities_array as $key => $value)
{
    echo $value['city'].' '.$value['region'].' '.$value['country'].' '.$value['latitude'].' '.$value['longitude']."\r\n";
}

如果您搜索特定的ID，那么任务就更容易了

foreach($cities_array as $key => $value)
{
if($key==id)
    echo $value['city'].' '.$value['region'].' '.$value['country'].' '.$value['latitude'].' '.$value['longitude']."\r\n";
}

如果您知道该ID，则可以直接访问您的城市名称：
