This statement does not serve a purpose anymore.
In a long forgotten world it indicated the main version number of PHP which the code in the file was compatible to.
http://pear.php.net/manual/en/standards.sample.php
But since PHP 5.1 and later this is only marginally true.
Thus I propose to remove it from CakePHP.
Writing assertContains() or assertRegExp for generated code is a pain and making the test cover most part of it is very difficult.
Things like:
```
} else {
}
```
Are very easy to happen (which was the case) and was not being covered by the test.
As recommended by the Cookbook:
http://book.cakephp.org/2.0/en/development/testing.html#testing-controllers
> When testing actions that contain redirect() and other code following the redirect it is generally a good idea to return when redirecting. The reason for this, is that redirect() is mocked in testing, and does not exit like normal. And instead of your code exiting, it will continue to run code following the redirect.
