遍历数组中的所有键并获取键名(列名）和键值 - Loop over all keys in array and obtain key name (column name) and key value

Loop over all keys in array and obtain key name (column name) and key value

var_dump( $resultArray );
array
  0 => 
    array
      'id' => string '1' (length=1)
      0 => string '1' (length=1)
      'fname' => string 'a' (length=1)
      1 => string 'a' (length=1)
      'lname' => string 'z' (length=1)
      2 => string 'z' (length=1)

如何遍历 $resultArray[0] 以获取该键的键值（列名）和相应值（而不是手动硬编码echo $resultArray[0]['id'];等。

结果应为：

KEYID: 0, KEY_VALUE: id, VALUE: 1
KEYID: 1, KEY_VALUE: fname, VALUE: a
KEYID: 2, KEY_VALUE: lname, VALUE: z

做这样的事情,...我没有测试它，所以我不能保证它是否有效，但方法应该是正确的：

foreach ($resultArray as $key => $value) {
   foreach ($value as $subKey => $subValue) {
       echo('KEYID: ' .$key . ', KEY_VALUE: ' . $subKey . ' VALUE: ' .$subValue. "'n");
   }
}
