插入不成功

<?php
$connect=(mysql_connect('localhost','root','ccnu'));
if($connect)
echo 1;
echo "<br/>";
$connect=mysql_select_db('mydata');
if($connect);
{
echo "victory";
}
mysql_query("set name 'utf8'");
$name="概率统计";
$time="110";
$teacher="叶大师";

$sql="insert into ktable(name,time,teacher) values('$name','$time','$teacher')";

mysql_query($sql);//执行插入语句
$uid =mysql_insert_id();
echo $uid;
//mysql_close($connect);
//insert into ktable(name,time,teacher) values('".$name."','".$time."','".$teacher."')
?>

求问怎么一直插入失败
