解析错误MySQL的2个变量

我的代码是这样的解析错误MySQL的2个变量

$newentry = " 
    UPDATE url 
    FROM auction_media 
    JOIN auctions ON auction_media.auction_id = auctions.auction_id            
    SET media_url = '$row2['url']/$match[0]' 
    WHERE media_type = '3'";

我得到的错误是

解析错误：语法错误，意想不到的T_ENCAPSED_AND_WHITESPACE，期待T_STRING或T_VARIABLE或T_NUM_STRING

这段代码似乎是错误的：

SET media_url = '$row2['url']/$match[0]'

更正如下：

SET media_url = '" . $row2['url'] . "/" . $match[0] . "'

试试这个：

$newentry = "UPDATE url FROM auction_media JOIN auctions ON auction_media.auction_id = auctions.auction_id SET media_url = '" . $row2['url'] . "/" . $match[0] . "' WHERE media_type = '3'";

假设查询将实际工作：

$newentry = "UPDATE url 
    FROM auction_media 
    JOIN auctions 
     ON auction_media.auction_id = auctions.auction_id 
    SET media_url = '" . $row2['url'] . '/' . $match[0] . "' 
    WHERE media_type = '3'";
