Stream Filters

A filter is a final piece of code which may perform operations on data as it is being read from or written to a stream. Any number of filters may be stacked onto a stream. Custom filters can be defined in a PHP script using stream_filter_register or in an extension using the API Reference in 流的使用. To access the list of currently registered filters, use <span class="function">stream_get_filters.
