Steps to create connectivity.
1.Make a database in php my admin.
2.In the text editor create a config.php file and code this
<?php
$SERVER="localhost";
$USER_NAME="root";
$PASSWORD="";
$DATABASE="test_database";
$conn=mysqli_connect($SERVER,$USER_NAME,$PASSWORD,$DATABASE);
if(!$conn)
{
echo "Could not connect to the database ".mysqli_connect_errno();
}
?>
3.You have successfully created a connection with the database.
Explanation
1. $SERVER="localhost"==>In this the local server ip address is being assigned to
variable named $SERVER.
2.$USER_NAME="root"==>In this the username of the PhpMyAdmin will always be
root if you are working on the local server.
3.$PASSWORD=""==>Default password will be null.
4.$DATABASE="test_database"==>Name of the database which you have specified
in the phpMyAdmin.
All these four parameters must be passes inside the mysqli_connect() function which will return a status object which is stored in $conn variable.
