Assignment $2$: Form and Response: use PHP superglobal arrays. Due Date $04/01/2024$

This assignment aims to demonstrate the ability to create a data$-$driven PHP page and to use superglobal arrays.

Write a PHP script that lets the user view, insert, and update student information as shown in Figure Below.

Create a Student Class that holds the student information. The data are stored in a separate file called "data.in$.$php$"$ as an association array in which the key is student ID and the value is the student object. At the beginning initialize the array with at least five student objects.

View: The user sends the student ID to the script, which returns an HTML form filled with the student's details, which are stored in the student array that has been initialized in the "data.in$.$php$"$ file.

Insert: The user sends the student data to the script which instantiates a student object and inserts it into the student array; but making sure the student is not stored in the array. If the student stored return an error message to inform the user.

Update: The user sends the new student's information to the script which modifies the student information in the student array.
