It is crucial to consider the backend infrastructure, such as database connectivity, when converting a PHP website into a mobile app to ensure seamless data transfer and functionality. This involves adapting the database queries and connections to work efficiently with the mobile app platform.

// Example PHP code snippet for database connectivity in a mobile app
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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