PHP数组转换

Question

源数组：
$attributes=array(
'Users'=>array(
'Name'=>'Name',
),
'Address'=>'Address',
'Tags'=>array(
0=>array(
'Key'=>'Key',
'Value'=>'Value',
),
1=>array(
'Key'=>'Key',
),
2=>array(
)
),
);
希望转换为如下数组：
$result=array(
'Users_Name'=>'Name',
'Address'=>'Address',
'Tags_0_Key'=>'Key',
'Tags_0_Value'=>'Value',
'Tags_1_Key'=>'Key',
//'Tags_2'=>'',
);
递归方式尝试了半天，依然没有解决，如何转换呢？

functiont($parent_key,$parent_array,&$data){foreach($parent_arrayas$k=>$v){if(is_array($v)){t("${parent_key}_${k}",$v,$data);}else{$data[trim("${parent_key}_${k}",'_')]=$v;}}}$data=array();$attributes=array('Users'=>array('Name'=>'Name',),'Address'=>'Address','Tags'=>array(0=>array('Key'=>'Key','Value'=>'Value',),1=>array('Key'=>'Key',),2=>array()),);t('',$attributes,$data);print_r($data);
