Question

我编写了这个脚本来从rss feed中提取项目并将它们转储到数据库中。但是，我运行脚本，它没有给我任何错误消息，它声称已正确输入信息，但当我输入phpMyAdmin并查看表是否存在并且信息已填入时我发现该表从未创建过第一名。我无法弄清楚我的生活中哪里有任何问题，但我认为我的CREATE TABLE行存在一些问题，但我无法确定。

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

问题与错过)行中的最终CREATE TABLE有关。另外，我创建了mysql函数作为变量而没有执行它。

所以我改变了：

$SQL = "INSERT INTO ".$db_table." (title, url, image, description, timestamp) VALUES ('".$title."', '".$url."', '".$image."', '".$description."', '".$timestamp."')";

要：

mysql_query("INSERT INTO ".$db_table." (title, url, image, description, timestamp) VALUES ('".$title."', '".$url."', '".$image."', '".$description."', '".$timestamp."')");

脚本不创建表
