逃脱后的正确语法？

Question

在转义后写入的正确语法是什么？

("SELECT torrent_download
FROM " . DB_PREFIX . "auctions WHERE
                auction_id='" . $item_details['auction_id'] . ); 

我得到的错误是意外的'）'

我尝试了各种各样的“和”但似乎没有工作

Answer 1

在最终的'之前，您似乎错过了$item_details['auction_id']的结束)，这将以双引号括起来"'");

("SELECT torrent_download
  FROM " . DB_PREFIX . "auctions WHERE
            auction_id='" . $item_details['auction_id'] . "'");

为了在双引号字符串中省去一点麻烦，我建议使用{}附件而不是连接所有引号。但是，您不能将常量DB_PREFIX括起来。

("SELECT torrent_download
  FROM " . DB_PREFIX . "auctions WHERE
        auction_id='{$item_details['auction_id']}'");

Answer 2

("SELECT torrent_download
 FROM " . DB_PREFIX . "auctions WHERE
            auction_id='" . $item_details['auction_id'] . "'");

你试过那个吗？它是“跟着'然后再”。

Answer 3

("SELECT torrent_download
FROM " . DB_PREFIX . "auctions WHERE
            auction_id='" . $item_details['auction_id'] ."'" );
