字串轉入二維數組

字串轉為二維數組
$str = array ( 'digest' => '2012', ), 1 => array ( 'digest' => '2011', ), 2 => array ( 'digest' => '2010', ), 3 => array ( 'digest' => '2009', ), 4 => array ( 'digest' => '2008', ), 5 => array ( 'digest' => '2007', ), ); ?>

需要轉成
Array
(
[0] => Array
(
[digest] => 2012
)

[1] => Array
(
[digest] => 2011
)

[2] => Array
(
[digest] => 2010
)

[3] => Array
(
[digest] => 2009
)

[4] => Array
(
[digest] => 2008
)

[5] => Array
(
[digest] => 2007
)

)
求高人幫忙啊

------解決方案--------------------
你字串是這樣的嗎？

$str = "array ( 'digest' => '2012'), 1 => array ( 'digest' => '2011' )........"

是的話

PHP code

 '2012'), 1 => array ( 'digest' => '2011' )";$arr=explode(',',$str);$temp=array();foreach($arr as $key=>$value){        $arr_temp=explode("'",$value);    $real_value=$arr_temp[3];    $temp[$key]['digest'] = $real_value;}print_r($temp);?>
