如何從這個數組回波值

Question

有人可以幫助我來呼應[城市]值，並從以下陣列[國家]值：

<?php 
    Array 
    (
    [0] => Array 
    (
    [uid] => 123456789 
    [name] => First Last Name 
    [current_location] => Array 
    (
    [city] => New York 
    [state] => New York 
    [country] => United States 
    [zip] => 
    [id] => 123456789 
    [name] => New York, New York 
    ) 

    [profile_url] => http://www.facebook.com/username 
    ) 

    ) 
?> 

感謝。

Answer 1

你有一個多維數組。你想試試這個：

echo $arr[0]['current_location']['city']; 
echo $arr[0]['current_location']['country']; 

Answer 2

像這樣：

echo $somearray[0]['current_location']['city']; 
echo $somearray[0]['current_location']['country']; 

Answer 3

正如已經指出的那樣，你有一個多維數組 - 換句話說內部數組的數組。

這種類型的數據通常是訪問這樣的：

foreach ($yourArray as $data) { 
    $locationData = $data['current_location']; 

    echo "user id " . $data['uid'] . "\n"; 
    echo " - city " . $locationData['city'] . "\n"; 
    echo " - country " . $locationData['country'] . "\n"; 
} 

所以，如果多於一個用戶出現在數據，你可以處理每一個。
