Most of yii beginner write parameter in main.php because thats pattern comes in installed yii framework. This is fine if you have less parameter but if you are building large web portal or application then it's very hard to manage every thing in mail.php because its main config file. So the best way is create seperate params.php in the same directory and include it in you main.php file. Check is below example of params.php and main.php files.

config/main.php :

'params'=>require(dirname(__FILE__).'/params.php'),

config/params.php :

<?php
return array(
 'defaultPageSize'=>10,
 'websiteName'=>'ezeelive.com',
 'copyrightInfo'=>'Copyright &copy; '.date("Y").' Ezeelive Technologies. All Rights Reserved.',
 ...
 ...
);
?>
