-Enter the student number, name, Chinese, mathematics, and English information of four students on the keyboard, calculate the average score of each student, and output
- The student's information includes student number, name, Chinese, mathematics, English, average grade, and the information of 4 students is stored in the array.

The above introduces the PHP keyboard to input the student number, name, Chinese, mathematics, and English information of four students, calculates the average score of each student, and outputs it, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
