What are some common pitfalls to avoid when setting up a SQL server on a root server for PHP development?

One common pitfall to avoid when setting up a SQL server on a root server for PHP development is failing to properly secure the SQL server. To prevent unauthorized access and potential security breaches, it is crucial to set strong passwords, limit user privileges, and regularly update the SQL server software.

php 
// Example of setting a strong password for the SQL server
$servername = "localhost";
$username = "root";
$password = "myStrongPassword123";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
