PHP connection to a SQLite database?

I need to use PHP to create a connection to a SQLite database.

Is there a similar call, like this connection to a MySql database?

// Creating a connection
$conn = new mysqli($servername, $username, $password);

Is this the trick?

<?php
   class MyDB extends SQLite3 {
      function __construct() {
         $this->open('test.db');
      }
   }
   $db = new MyDB();
   if(!$db) {
      echo $db->lastErrorMsg();
   } else {
      echo "Opened database successfully\n";
   }
?>
