In the previous example, you saw that you can use either the fully qualified filter class
name or its short alias when instantiating the filter from the array. The short aliases for
the standard filters are defined by the FilterPluginManager
class.
The
FilterPluginManager
class defines the short aliases for the standard filters.
A standard filter's alias is typically the same as the class name. For example, the class
Zend\Filter\StringTrim
has the short alias StringTrim
.
The filter plugin manager is internally used by the InputFilter
container class for
instantiating the standard filters.
