stream_filter_append(). Any data
remaining in the filter's internal buffer will be flushed
through to the next filter before removing it.

<?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");
