What are common challenges faced when integrating a CMS with PHP and MySQL?

One common challenge when integrating a CMS with PHP and MySQL is ensuring proper database connectivity and handling errors that may arise during the connection process. To solve this, it is important to use try-catch blocks to catch any exceptions that may occur when connecting to the database. 

try {
    $conn = new PDO("mysql:host=localhost;dbname=database", "username", "password");
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully";
} catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
