------ Solution --------------------
Is your first code output? What can be seen?
Mysql_query ("set names 'utf-8 ");
Should be
Mysql_query ("set names 'utf8 ");

If your program file is UTF-8 encoded, use
Mysql_query ("set names 'utf8 ");
If your program file is gbk encoded, use
Mysql_query ("set names 'gb2312 '");
Preferably
Mysql_query ("set names 'gbk '");

Select one

The second part of the code has no language declaration. even if it is inserted, it may be garbled.
$ SQL = "insert into lyb (user, post) values ('$ user',' $ Post ')";
$ Qu = mysql_query ($ SQL) or die (mysql_error ());
Let's take a look at all the errors.
