11 | Setup 
12 | -----------
13 | 1) Create a new database in MySQL - recommended <br>
14 | 2) Run the following SQL code to create the tables in the database
15 | 
16 | ```
17 | CREATE TABLE users(
18 |     id int NOT NULL AUTO_INCREMENT,
19 |     username varchar(15) NOT NULL,
20 |     password varchar(32) NOT NULL,
21 |     followers int DEFAULT 0,
22 |     following int DEFAULT 0,
23 |     tweets int DEFAULT 0,
24 |     PRIMARY KEY (id)
25 | );
26 | 
27 | CREATE TABLE following(
28 |     id int NOT NULL AUTO_INCREMENT,
29 |     user1_id int REFERENCES `users` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
30 |     user2_id int REFERENCES `users` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
31 |     PRIMARY KEY (id)
32 | );
33 | 
34 | CREATE TABLE tweets(
35 |     id int NOT NULL AUTO_INCREMENT,
36 |     username varchar(15) NOT NULL,
37 |     user_id int REFERENCES `users` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
38 |     tweet varchar(140) NOT NULL,
39 |     timestamp bigint(20) NOT NULL,
40 |     PRIMARY KEY (id)
41 | );
42 | ```
43 | 3) Open `connect.php` and edit the database information. The following three setting variables are required in order to establish a connection with the database.
44 | 
45 | ```
46 | $dbuser	= "USERNAME"; //Username that is allowed to access the database
47 | $dbpass	= "PASSWORD"; //Password
48 | $dbname	= "NAME-OF-THE-DATABASE"; //Name of the database
49 | ```
50 | 
51 | 
52 | 


--------------------------------------------------------------------------------
/connect.php:
--------------------------------------------------------------------------------
 1 | <?php
 2 | //Edit the following fields in order to establish a connection with MySQL
 3 | //********************************************************************************
 4 | $dbhost	= "localhost"; //Leave this as 'localhost' once uploaded on a server
 5 | $dbuser	= "USERNAME"; //Username that is allowed to access the database
 6 | $dbpass	= "PASSWORD"; //Password
 7 | $dbname	= "NAME-OF-THE-DATABASE"; //Name of the database
 8 | //********************************************************************************
 9 | 
10 | $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ("Error connecting to database");
11 | mysql_select_db($dbname);
