Static Filter
Deprecated
This filter is deprecated since version 2.15.0 and will be removed in version 3.0.
If it is inconvenient to load a given filter class and create an instance of
the filter, you can use StaticFilter
with it's method execute()
as an
alternative invocation style. The first argument of this method is a data input
value that you would pass to the filter()
method. The second argument is a
string, which corresponds to the basename of the filter class, relative to the
Laminas\Filter
namespace. The execute()
method automatically loads the class,
creates an instance, and applies the filter()
method to the data input.
echo StaticFilter::execute('&', 'HtmlEntities');
You can also pass an array of constructor arguments, if they are needed for the filter class:
echo StaticFilter::execute(
'"',
'HtmlEntities',
['quotestyle' => ENT_QUOTES]
);
The static usage can be convenient for invoking a filter ad hoc, but if you
have the need to run a filter for multiple inputs, it's more efficient to
create an instance of the filter and invoke it. instance of the filter object
and calling its filter()
method.
Additionally, filter chains allow you to instantiate and run multiple filters on demand to process sets of input data.
Using custom Filters
You can set and receive the FilterPluginManager
for the StaticFilter
to
amend the standard filter classes:
$pluginManager = StaticFilter::getPluginManager()
->setInvokableClass('myNewFilter', 'MyCustom\Filter\MyNewFilter');
StaticFilter::setPluginManager(new MyFilterPluginManager());
This is useful when adding custom filters to be used by the StaticFilter
.
