Are there specific configuration settings in PHP or Apache that could be affecting the ability to connect to a database?

The issue of not being able to connect to a database in PHP could be caused by configuration settings in PHP or Apache. To solve this, you may need to check the database connection settings in your PHP code, ensure that the database server is running and accessible, and verify that the necessary PHP extensions for database connectivity are enabled in your PHP configuration. 

// Example code snippet to connect to a MySQL database in PHP
$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";
