Answer 1

Missing quotes around search condition

"SELECT * from Student_registration WHERE area LIKE '%". $area."%'";

or

"SELECT * from Student_registration WHERE area LIKE concat('%', '" .$area. ",'%'";

Answer 2

您缺少用单引号引起来的字符串：

$sql = "SELECT * from Student_registration WHERE area LIKE '%".$area."%'";
