读取数据库有的设置选中状态

<table class="table table-striped">
   <?php
	$sql = "select * from quanxian";
	$arr = $db->query($sql);
	$sqlqx = "select Qxian from users where uid ='{$uid}'";//读取数据库
	$qx =$db->strquery($sqlqx);
	$arrqx = explode(',',$qx);//字符串转为数组
	foreach($arr as $v)
	{  
				
	 if(in_array($v[0],$arrqx))// 编译查看不是在数组 中,在数组 中为选中状态
	{
	echo "<tr>
		 <td>
		<input type='checkbox' checked='checked' class='qx' id='Qxian' value='$v[0]' /> {$v[1]}
		 </td>
		</tr>"; 
		}
	 else
	 {
		echo "<tr>
		   <td>
			<input type='checkbox' class='qx' id='Qxian' value='$v[0]' /> {$v[1]}
		 </td>
		</tr>";
		 }
	}
?>
          </table>
