What is mean by @file tag in dockblock

I am using phpCheckstyle phpcheckstyle for standardizing my code commenting. After validating file in warning it suggests “Doc block comments should include information about file(@file) for each PHP file” The warning resolves when adding @file tag — I want to know what value should I assign to this tag (What it indicates).

And what is the difference between @file and @filesource

Thanks,

According to code standards @file is a Doc-Block comment (for each file) and is a description of what this file is intended for.

For example, imagine your model file Users.php with all its methods, well, you can put in your file comment something like this:

/**
 @file
   This file will store all model methods to recover/update/delete Users.php
 ....
*/

@filesource, afaik, is similar to @example tag, you can take a look to pear documentation here
