checkbox

checkbox 中 name 的命名需要以数组的形式，如

<form action="solve.php" method="post">
    <input type="checkbox" name="hb[]" value="jiba">jiba
    <input type="checkbox" name="hb[]" value="jibaba">jibaba
    <input type="submit">
</form>


$row=$_POST['hb'];
foreach ($row as $value) {
    echo $value.'<br />';
}
