PHP中如何循环输出数组?
foreach ($list as $a){
echo $a['upid'] .'-'. $a['title'];
foreach ($a['list'] as $b){
echo $b['title'];
}
}
这样写对嘛?
为什么输出不对呢?

foreach ($list as $v=>$a)
{
/*echo $a['upid'] .'-'. $a['title'];
foreach ($a['list'] as $b){
echo $b['title'];
}*/
if($v=='list')
{
foreach ($a as $b)
{
echo $b;
}
}
else
{
echo $a;
}
}
这样就行了..
