1. Consider a text file which stores students data. Each row contains 4 fields (student ID, student name, score of midterm exam 1, and score of midterm exam 2), separated by tabs.
2. Write a PHP script to read the data from this text file, and create a table "student_xxxx" in the database. Here, "xxxx" should be replace with a unique number so that your table name does not conflict with your classmate. (Maybe you can choose the last four digits of your student number.)
3. If the PHP script runs successfully, it may terminate silently. You may verify the result as follows.
   
4. If you found that your script encounters an error when you ran it repeatedly, complaining that the table had already been created, you may delete your table with a SQL command "DROP TABLE IF EXISTS student_xxxx".
