Example 1: php connect to mysql
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {

Example 4: how to link html with php
/* PHP code can be easily injected into a standard HTML page. As a rule,
* files with mixed content of that kind have .phtml extention. The workflow
* is the same as for pure .php scripts: one should setup web-server to
* handle .phtml files the same way it handles .php - .phtml should be passed
* to PHP engine, and the outcome gotta be sent to a visitor. PHP will parse
* the .phtml and process everything inside tags <?php [..] ?>, ignoring the
* rest. I.e. the php code pieces in .phtml will be replaced in outcome with
* results of their processing, and HTML / CSS / JavaScript code in .phtml,
* as well as text content, will be displayed in browser as is. The one and
* only strict rule - your .phtml mixes must always start with PHP tag
* sequence <?php ?>, otherwise they won't be preprocessed by PHP engine.
