$RSQL=sprintf(self::GETQATT,$CID);
$us=$this->mysql->getData($RSQl);
echo $RSQL;
$uc=count($us);
if($uc>0)
{
foreach($us as $u)
{
echo $u['UID'];
}
}
Copy after login
$uc明明大于0的,foreach为什么进入不了
------解决方案-------------------- print_r($us); 看看
------解决方案-------------------- foreach前把$us输出一下
PHP code
if($uc>0)
{
print_r($us);
foreach($us as $u)
{
echo "#TEST#";
echo $u['UID'];
}
}
