How to Connect Database in PHP?

Answer 1

It's very simple

<?php
$host="localhost"; // name of your host
$user="root"; //database user
$password=""; // password of database
$dbName="DB Name"; // Database name

$connect = mysqli_connect($localhost, $user, $password, $dbName) ;

//Now, to check connection
if(!$connect) {
echo("database not connected ") ;
}

?>

Answer 2

$conn = new PDO("mysql: host=localhost; dbname=name", "root", "root_password");

host - ip address of host you wanna connect to (or localhost).
dbname - name of database
root - user name
root_password - password of user

then you can do something like:
$conn->query("SELECT * FROM table");

If you want to read some more about it type PDO in google ^^

Answer 3

^I do not recommend Shan's way to connect. PDO is safer and newer way :)

Answer 4

there are many ways to connect database in php, two are already mention in comment and I'll prefer PDO method which is new and more secure but if you are starter then go to other one that is posted by Shan.
