PHPCS native utility functions.
Backport of the latest versions of PHPCS native utility functions to make them available in older PHPCS versions without the bugs and other quirks that the older versions of the native functions had.
Additionally, this class works round the following tokenizer issues for any affected utility functions:
-
readonlyclasses. - Constructor property promotion with
readonlywithout visibility. - OO methods called
self,parentorstatic.
Most functions in this class will have a related twin-function in the relevant
class in the PHPCSUtils\Utils namespace.
These will be indicated with @see tags in the docblock of the function.
The PHPCSUtils native twin-functions will often have additional features and/or improved functionality, but will generally be fully compatible with the PHPCS native functions. The differences between the functions here and the twin functions are documented in the docblock of the respective twin-function.
