Move escaping functions related functionality to dedicated
EscapingFunctionsTrait
The escaping function lists are only used by a small set of sniffs, so are better placed in a dedicated trait.
The choice for a
trait
over aclass
is due to thepublic
properties allowing for adding additional functions to these lists.Moving both the base function lists + the
public
properties to the same trait will allow us to encapsulate all the functionality related to the use of these lists in one place.The
$escapingFunctions
and the$autoEscapedFunctions
properties, containing the base lists, have also been madeprivate
.Checking whether or not something is an escaping function should now be done by calling the
EscapingFunctionsTrait::is_escaping_function()
and/or theEscapingFunctionsTrait::is_auto_escaped_function()
methods.Related to #1465
