無法在PHP中返回數組中元素的值

-1

我正在使用geoplugin來了解用戶的國家/地區。在網站上，他們寫下面的代碼：無法在PHP中返回數組中元素的值

echo var_export(unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$_SERVER['REMOTE_ADDR'])));

，其結果是：

array (
'geoplugin_request' => '59.179.68.40', 
'geoplugin_status' => 206, 
'geoplugin_credit' => 'Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com.', 
'geoplugin_city' => '', 
'geoplugin_region' => '', 
'geoplugin_areaCode' => '0', 
'geoplugin_dmaCode' => '0', 
'geoplugin_countryCode' => 'IN', 
'geoplugin_countryName' => 'India', 
'geoplugin_continentCode' => 'AS', 
'geoplugin_latitude' => '20', 
'geoplugin_longitude' => '77', 
'geoplugin_regionCode' => '', 
'geoplugin_regionName' => NULL, 
'geoplugin_currencyCode' => 'INR', 
'geoplugin_currencySymbol' => '₨', 
'geoplugin_currencySymbol_UTF8' => '₨', 
'geoplugin_currencyConverter' => '63.4999', 
)

現在，我試圖將其存儲在一個這樣的數組：

$locArray = var_export(unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$_SERVER['REMOTE_ADDR'])));

和呼應位置如：

echo $locArray[8];

In呼應第九元素，這樣的代碼回聲完整陣列代替：

array ('geoplugin_request' => '59.179.68.40', 'geoplugin_status' => 206, 'geoplugin_credit' => 'Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com.', 'geoplugin_city' => '', 'geoplugin_region' => '', 'geoplugin_areaCode' => '0', 'geoplugin_dmaCode' => '0', 'geoplugin_countryCode' => 'IN', 'geoplugin_countryName' => 'India', 'geoplugin_continentCode' => 'AS', 'geoplugin_latitude' => '20', 'geoplugin_longitude' => '77', 'geoplugin_regionCode' => '', 'geoplugin_regionName' => NULL, 'geoplugin_currencyCode' => 'INR', 'geoplugin_currencySymbol' => '₨', 'geoplugin_currencySymbol_UTF8' => 'â‚¨', 'geoplugin_currencyConverter' => '63.4999',)

我怎樣才能從中提取只是國家的名字嗎？

嗯，好像在'$ locArray'第九元素本身是一個數組。您似乎已經知道如何訪問數組。有什麼問題？ –

那我該如何提取國名呢？ –

假設你有'$ data = array（'geoplugin_countryName'=>'foo'）;'，你會怎麼做？ –

$arr = unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$_SERVER['REMOTE_ADDR'])); 
// then just access the country index. 
echo $arr['geoplugin_countryCode'];

編輯：

您正在嘗試echo $locArray[8];但沒有指標8，因爲它是關聯數組（一個數組，其索引是字符串）。

這回像

array (
    'geoplugin_request' => '192.168.4.188', 
    'geoplugin_status' => 404, 
    'geoplugin_credit' => 'Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com.', 
    'geoplugin_city' => '', 
    'geoplugin_region' => '', 
    'geoplugin_areaCode' => '', 
    'geoplugin_dmaCode' => '', 
    'geoplugin_countryCode' => '', 
    'geoplugin_countryName' => '', 
    'geoplugin_continentCode' => '', 
    'geoplugin_latitude' => '0', 
    'geoplugin_longitude' => '0', 
    'geoplugin_regionCode' => '', 
    'geoplugin_regionName' => NULL, 
    'geoplugin_currencyCode' => NULL, 
    'geoplugin_currencySymbol' => NULL, 
    'geoplugin_currencySymbol_UTF8' => '', 
    'geoplugin_currencyConverter' => '0', 
)

數組，然後你可以使用像

echo $locArray['geoplugin_request'];
