To connect to a MySQL database from PHP, you can use the following steps: Install the PHP MySQL extension if it is not already installed. This can usually be done by installing the php-mysql package through your package manager. Create a PHP script that will handle the database connection. In this script, use the mysqli_connect function to connect to the database. This function takes four arguments: the server name, the username, the password, and the database name. $server = "localhost"; $username = "username"; $password = "password"; $database = "database_name"; $conn = mysqli_connect($server, $username, $password, $database); If the connection was successful, mysqli_connect will return a connection resource. You can then use this resource to issue queries to the database. if ($conn) { // connection was successful, issue queries here } else { // connection failed, handle the error } To issue a query, use the mysqli_query function, which takes two arguments: the connection resource and the query string. $result = mysqli_query($conn, "SELECT * FROM users"); To process the results of a SELECT query, you can use the mysqli_fetch_assoc function in a loop. This function returns an associative array representing the next row in the result set, or NULL if there are no more rows. while ($row = mysqli_fetch_assoc($result)) { // process the row } Don't forget to close the connection when you are done. You can use the mysqli_close function for this. mysqli_close($conn);
