我有一个我设计的表单，我的意图是接受任何UTF-8内容并将其插入MySQL数据库。我使用PDO和charset utf-8作为连接数据库的编码。当内容包含单引号等字符时，插入查询仍然失败。在使用查询之前，我应该在输入内容上使用什么内置函数。下面是插入数据库之前形成的示例查询
INSERT INTO dbname.table
(input_xml)
VALUES
('<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<ip_Input>
<ip_xml>
Qaiku.com – What Can We
Learn From Failure?By Guest Blogger, September 11, 2012, Leave a
CommentEditor's note: I think we in the tech press have the tendency to
focus on the positive stories and forget about the startups that didn't live up
their expectations. Our Sofanatics coverage this past week has been one of the
few times we've covered abandoned projects, which is a pitty because there are a
lot to learn from "failures." Below we have a long read from Eero Holmila which
is one part eulogy, and another part what he's learned from the now-announced
shutdown of Qaiku.com.Qaiku.com might be a familiar name for some of the
readers of Arctic Startup. However, I am quite sure that the background and the
rough road from high hopes to a bitter decline probably is not. I am the CEO of
Rohea, a company behind a handful of quite successful Finnish websites like
Kotikokki.net, Kuvake.net, Mikseri.net and of course a less successful
Qaiku.com.I am going to share some lessons learned through the trip. I hope
some of it might be of use, spark up ideas or if nothing else, be at least a bit
entertaining. One last important disclaimer: all the opinions are my own.Now
without further delay, this is the story of
Qaiku.
