引用一個動態變量？

Question

for ($count = 1; $count <= 5; ++$count) { 
    $test = ${'node->field_aw_score_' . $count}[LANGUAGE_NONE][0]['value']; 
    echo $test; 
} 

拋出錯誤：

Notice: Undefined variable: node->field_aw_score_1 
Notice: Undefined variable: node->field_aw_score_2 
Notice: Undefined variable: node->field_aw_score_3 
Notice: Undefined variable: node->field_aw_score_4 
Notice: Undefined variable: node->field_aw_score_5 

然而，變數確實存在。我想引用：

$node->field_aw_score_1[LANGUAGE_NONE][0]['value'] 

然後

$node->field_aw_score_2[LANGUAGE_NONE][0]['value'] 

等動態變量。我究竟做錯了什麼？謝謝。

試試這個：

$node->{'field_aw_score_' . $count}
