What password and username do I use for mysql_connect()?
Question
Okay so as you will probably be able to tell but, I am pretty new to MySQL and PHP and I have ran into a problem.. In my connect.php , which connects to the server, I don't know if my password and username along with the port are right. Now the reason it says port 8080 is because one of my other web development programs was using port 80 so I went in to the Apache files and changed to port, so now when I log into phpMyAdmin I have to type localhost:8080 . I don't know if that has to do with mysql_connect , also I checked on phpMyAdmin and it says my username is root and my password is empty. Does the empty password mess with MySQL_connect() ? Thanks, here's the code:
connect.php :
<?php
//This file allows me to easily connect to my database
mysql_connect("localhost:8080", "root", "");//connects to database, params are ("servername", "username", "password");
mysql_select_db("membersystem");//selects the table from db
?>
login.php :
<?php
error_reporting (E_ALL ^ E_NOTICE);//saves us from getting undefined index error
session_start();//makes it a sesion based system
?>

You dont need to use 8080 simply use localhost because that port number is not related to mysql but related to webserver. Inorder to address the webserver only you need to use it like localhost:8080/project-name/
And dont use mysql_* methods. will get disappointed in future. Use mysqli
$con = new mysqli("localhost","root","","membersystem") or die('Connection failed');
$result = $con->query("Your query here");
or else you can use the same in procedural method with mysqli_* functions. But i prefer to go along with object oriented php.
Refer the documentation. http://php.net/manual/en/book.mysqli.php

Make connection like
$conn=mysqli_connect("localhost","root","","membersystem");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
and w3schools link is http://www.w3schools.com/php/func_mysqli_select_db.asp
