输出数组不加单引号,该怎么处理

//数据库连接 
$rs = mysql_query("select id,degree,min,max,prize,v from magic_config"); 
	while($r = mysql_fetch_assoc($rs)) {  
	$prize_arr[] = $r; } 

$prize_arr = array( 
		array('id'=>'1','degree'=>97,'min'=>'1','max'=>'5','prize'=>'不要放弃','v'=>'1'), 
		array('id'=>'2','degree'=>98,'min'=>'7','max'=>'35','prize'=>'不要灰心','v'=>'1'),); 

$prize_arr = array( 
        array('id'=>'1','degree'=>97,'min'=>'1','max'=>'5','prize'=>'不要放弃','v'=>'1'), 
        array('id'=>'2','degree'=>98,'min'=>'7','max'=>'35','prize'=>'不要灰心','v'=>'1'),); 
foreach ($prize_arr as $key => $value) {
	$prize_arr[$key]['degree'] = (int) $value['degree'];
}
var_dump($prize_arr);
