(no version information, might be only in CVS)php_stream_filter_register_factory -- Registers a filter factory with the Streams API
Descriptionint php_stream_filter_register_factory ( const char * filterpattern, php_stream_filter_factory * factory)
Use this function to register a filter factory with the name given by filterpattern. filterpattern can be either a normal string name (i.e. myfilter) or a global pattern (i.e. myfilterclass.*) to allow a single filter to perform different operations depending on the exact name of the filter invoked (i.e. myfilterclass.foo, myfilterclass.bar, etc...)
Note: Filters registered by a loadable extension must be certain to call php_stream_filter_unregister_factory() during MSHUTDOWN.
