}
mysql_select_db("blog",$conn) or die(mysql_error());
mysql_query("set names utf8");
$sql="insert into comment (id,article_comment) value ('$id','$article_comment')";
//我自己在mysql里面输入insert into comment (id,article_comment) value ('8','aaa');可以插入内容。
mysql_query("set names utf8");
$res=mysql_query($sql) or die(mysql_error());
if($res){
header("location:index.php");
}
