$_POST['flags']=array(1,2,3,4,'a','b',"c");
foreach(($_POST['flags']) as $v){
echo $_html = $v.',';
}
echo $_html;
?>
有点纳闷
第一个:echo $_html = $v.','; 得到值是1,2,3,4,a,b,c, 我明白
第二个:echo $_html; 得到值应该和上面的一样,可以为什么得到的是c,
------解决方案--------------------
foreach
你在循环内赋值,那么每一次这个值都给刷新 最后得到循环的最后一个值 所以就是c.
------解决方案--------------------
------解决方案--------------------
$v.',';
它俩合起来赋值给html的,不是html合起$v.','
------解决方案--------------------
要想得到你希望的结果
改
- PHP code
foreach(($_POST['flags']) as $v){ echo $v.','; $_html .= $v.','; } <div class="clear"> </div>
