使用PHP插入数据库时​​如何避免引号

我对PHP非常新，如果听起来像这么简单的问题...：）

I'm quite new to PHP so sorry if sounds such an easy problem... :)

当插入内容时，我有错误信息引用到我的数据库。
这是我试图逃避引号，但没有工作：

I'm having an error message when inserting content which contains quotes into my db. here's what I tried trying to escape the quotes but didn't work:

$con = mysql_connect("localhost","xxxx","xxxxx");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("test", $con);

$nowdate = date('d-m-Y')

$title =  sprintf($_POST[title], mysql_real_escape_string($_POST[title]));

$body = sprintf($_POST[body], mysql_real_escape_string($_POST[body]));

$sql="INSERT INTO articles (title, body, date) VALUES ('$title','$body','$nowdate'),";

if (!mysql_query($sql,$con))
  {

die('Error: ' . mysql_error());

}

header('Location: index.php');

您可以提供任何解决方案吗？

Could you provide any solution please?

提前感谢
