PHP的多維數組 - foreach循環

Question

我有一個問題，得到數組值「lat」和「long」，而不會深入foreach函數。陣列：

array(1) { 
    ["Berlin, Germany(All airports)"]=> 
    array(1) { 
    ["Berlin Brandenburg Willy Brandt(BER)"]=> 
    array(2) { 
     ["lat"]=> 
     string(9) "52.366667" 
     ["lon"]=> 
     string(9) "13.503333" 
    } 
    } 

}

功能：

foreach($results as $key => $val){ 
    //here i want to reach lat and long without additional foreach loop 
} 

謝謝大家的答案。

Answer 1

foreach($results as $key => $val){ 
    $temp = current($val); # fetch first value, which is array in your example 
    echo $temp['lat']; 
}
