How can reliance on specific server configurations impact the functionality of PHP scripts during a migration?

Reliance on specific server configurations can impact the functionality of PHP scripts during a migration if the new server does not have the same configurations. To solve this issue, it is important to make the PHP scripts as server-agnostic as possible by avoiding hardcoding server-specific settings and using more universal configurations. 

// Example of making PHP script server-agnostic by using universal configurations
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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