You need to select the id's in your MYSQL table with the id you want to check and then count the rows. If the row count is 0 then the id doesn't exist.

     $query = mysql_query("SELECT * FROM     your_table WHERE id='$id'");
     $count = mysql_num_rows($query);
     If($count!=0){
     // id exists
     } else {
     // id doesn't exist
     }
