Warning: Invalid argument supplied for foreach()
问题Warning: Invalid argument supplied for foreach() in 完善解决方案
将报错的语句做如下修改（例）：

把

QUOTE:
foreach($extcredits as $id => $credit)
{
if($credit['ratio'])
{
$exchcredits[$id] = $credit;
}
}

改为

QUOTE:
if(is_array($extcredits)) //add
{
foreach($extcredits as $id => $credit)
{
if($credit['ratio'])
{
$exchcredits[$id] = $credit;
}
}
} //add

或

QUOTE:
foreach((array)$extcredits as $id => $credit)
{
if($credit['ratio'])
{
$exchcredits[$id] = $credit;
}
}
造成这个错误的原因多数是因为论坛升级、编码转换造成的！
如果对PHP熟悉的人，可以直接找到出错的地方，分析出错信息是对哪个数据库表操作时造成的（一般都是论坛的基本数据表），然后，找到相应表的原版数据导进去，问题可解决。
如果对PHP不熟悉的人，可以按出错信息提示的位置，用2楼的修改方法进行修改，问题可解决。
