Question

Can someone tell me how to fix this error?

Parse error: syntax error, unexpected ‘(‘, expecting ‘,’ or ‘;’ in
/path/folders/etc/domain/protected/controllers/SiteController.php
on line 6

This is what’s on line 6:

const URL = Yii::app()->params['url'];

This works, but I need to define all parameters in a single config file, which is why I changed it to the code above:

const URL = 'http://domain.com/file.php';

From PHP: constant – Manual:

The value must be a constant expression, not (for example) a variable, a property, a result of a mathematical operation, or a function call.

A constant is by definition, constant. If you need to give it a computed value, use a variable instead.
