What are the common challenges faced when integrating Zend Framework into an existing PHP project?

One common challenge when integrating Zend Framework into an existing PHP project is dealing with conflicts between existing code and Zend Framework's conventions. To solve this, you can carefully plan the integration process, refactor existing code to adhere to Zend Framework's standards, and gradually introduce Zend Framework components into the project. 

// Example code snippet demonstrating gradual integration of Zend Framework components
// Step 1: Refactor existing code to adhere to Zend Framework's standards
// Step 2: Introduce Zend Framework autoloading
require_once 'Zend/Loader/Autoloader.php';
$autoloader = Zend_Loader_Autoloader::getInstance();

// Step 3: Start using Zend Framework components in your project
$zendDb = new Zend_Db_Adapter_Pdo_Mysql(array(
    'host'     => 'localhost',
    'username' => 'username',
    'password' => 'password',
    'dbname'   => 'database'
));
