如何修复嵌套循环，因为它显示每行的所有值而不是每行一个值？

Answer 1

您需要以某种方式构建该数组，以便知道索引处的值是什么，然后打印出像 $upc[$i] 这样的值。

此外，如果这是您真正的 sql 语句，您应该始终将参数用 '' 括起来，并确保转义所有输入。

Answer 2

解决方案是：数组 $upc ，索引为 $i 减 1。

echo $html->input('Table/count'.$i, array('class'=>'inputbox','size'=>'3', 'value'=> $upc[$i-1]['table_name']['count'] ));
