stream_filter_remove -- Remove a filter from a stream

## Description

bool stream_filter_remove ( resource stream_filter )

Removes a stream filter previously added to a stream with stream_filter_prepend() or stream_filter_append(). Any data remaining in the filter's internal buffer will be flushed through to the next filter before removing it.

Example 1. Dynamicly refiltering a stream
`<?php /* Open a test file for reading and writing */ $fp = fopen("test.txt", "rw"); $rot13_filter = stream_filter_append($fp, "string.rot13", STREAM_FILTER_WRITE); fwrite($fp, "This is "); stream_filter_remove($rot13_filter); fwrite($fp, "a test\n"); rewind($fp); fpassthru($fp); fclose($fp); /* Expected Output --------------- Guvf vf a test */ ?>`
