引用一个动态变量？

Question

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

抛出错误：

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，变数确实存在。我想引用：

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

然后

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

等动态变量。我究竟做错了什么？谢谢。

试试这个：

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