练习题一：

设置数组
$attr = array(
array("n001","汉族"),
array("n002","回族"),
array("n003","苗族"),
array("n004","维吾尔族"),
);

//1.要求用下拉列表的样式显示在页面上
<?php
/*foreach($a as $v)
{
echo"<option>{$v[0]}</option>";
}?>
</select>
<select>
<?php
foreach($a as $v)
{
echo "<option>{$v[1]}</option>";
}*/
?>
//2.要求用checkbox/radio 列表显示在页面上

<?php
foreach($a as $v)
{
echo
