array(

'cate1' => 'Protect',
'cate2' => 'Power Bank Protection',
'title' => '11111',
'material' => 'plastics',

);
$arrcolor=unserialize($arr[0]['color']);echo "<pre>";
print_r($arrcolor);
echo "</pre>";
/*Array

$arr = array(
    array('id'=>34,'cate1'=>'Protect','cate2'=>'Power Bank Protection','title'=>'11111','color'=>'a:4:{i:0;s:5:"black";i:1;s:3:"red";i:2;s:4:"blue";i:3;s:4:"pink";}','size'=>3,'country'=>'china', 'time'=>'2014-07-22 15:30:08'),
