Php Foreach Station仅显示数据库中的1条记录，而不是假定的数量
我正在从数据库中选择行。当我打印时，它显示3条记录，但在我的第二个foreach中，它只显示1条记录Php Foreach Station仅显示数据库中的1条记录，而不是假定的数量,php,Php,我正在从数据库中选择行。当我打印时，它显示3条记录，但在我的第二个foreach中，它只显示1条记录 //get productid $product = $database->prepare("SELECT * FROM bids,orders,products WHERE bids.bids_username=?

当我回显bids\u项目时，它只显示1个结果，而它应该遍历所有3个并回显所有结果。我的代码中有什么看起来不正确的地方吗？在第二个foreach中，只需替换
$result[] = $order->fetchAll();
您将收到一个数组。当前您正在覆盖foreach循环的下一个值。如果需要，请在下一个foreach中执行同样的操作。错误在第二个foreach循环中
foreach($productid as $product):
echo $product->bids_item;
//get btc address, check it's valid, then if isset run query below
$createorder->execute(array($username->username, $product->bids_item, $username->firstname, $username->lastname, $username->address1, $username->address2, $username->zipcode, $username->city, $username->country, 'jkjkjk', 0));
return 1;
endforeach;
