A built-in template for PHP setter methods. It is used, for example, when the "Add getter and setter" quick-fix is invoked.

Predefined variables take the following values:
${NAME}		Method name in CamelCase style without the "set" prefix with the first character capitalized. For example, a property name '_my_property' is converted to 'MyProperty'.
${CLASS_NAME}		Name of a containing class.
${SCALAR_TYPE_HINT}		Contains a scalar type hint if the language level is PHP 7.0 or higher
${RETURN_TYPE}		Indicates if the language level is PHP 7.0 or higher and thus a return type can be specified for function/methods
${FIELD_NAME}		Original property name as is.
${PARAM_NAME}		Parameter name for a setter. Almost the same as ${FIELD_NAME} but with the first underscore (if any) removed. For example, property name '_myProperty' will be converted to 'myProperty'.
${TYPE_HINT}		Type hint for the property or an empty string if not specified.
${DS}		Dollar sign, evaluates to a plain '$' character.
