Build a Website requiring php

Create a website for College Internship available opportunities. Create a database names internship having three tables: Interns, Opportunities and Assigned_opportunities. Interns (internID (primary key), email, password, firstName, lastName) Opportunities (opportunityID (Primary key), company, city, start_date, end_date, position, description) Assigned_opportunities (opportunityId, internID, date_selected, date_approved) For College Internship website, the first page is the Registration/log in page. New visitors must first get a username after entering his/her contact information. A valid email address (validate email address using regular expressions) will be used as username. Create a PHP document that accepts new user information from Registration/log in HTML form, validate email and password, and create a new user (username) by adding information in the database. Also confirm that email (username) does not already exist. If a username is created successfully, display a message. Returning visitors can enter their login information (email) and password to access the Available Opportunities page directly. Create a verify login PHP page to verify username and password match. After a user logs in, the web site must keep track of information about the user the entire time the client web browser navigates through the various page on the site. In other words, the web site must maintain information about the client session. Create Available Opportunities PHP document that display all available opportunities or display the last request internship opportunities. If the page is displaying the last request internship opportunities, there should also be a link/button, to display all the opportunities.
