note 118627 added to function.stream-filter-append

Note that stream filters applied to STDOUT are not called when outputting via echo or print. This is easily demonstrated with the standard ROT13 filter: <?php stream_filter_append( STDOUT, "string.rot13" ); print "Hello PHP\n"; // Prints "Hello PHP" fprintf( STDOUT, "Hello PHP\n" ); // Prints "Uryyb CUC" ?> If you want to filter STDOUT, you may have better luck with an output buffering callback added via ob_start: http://php.net/manual/en/function.ob-start.php At the time of this writing, there is an open PHP feature request to support echo and print for stream filters: https://bugs.php.net/bug.php?id=30583 ---- Server IP: 72.52.91.14 Probable Submitter: 208.181.56.5 ---- Manual Page -- http://php.net/manual/en/function.stream-filter-append.php Edit -- https://master.php.net/note/edit/118627 Del: integrated -- https://master.php.net/note/delete/118627/integrated Del: useless -- https://master.php.net/note/delete/118627/useless Del: bad code -- https://master.php.net/note/delete/118627/bad+code Del: spam -- https://master.php.net/note/delete/118627/spam Del: non-english -- https://master.php.net/note/delete/118627/non-english Del: in docs -- https://master.php.net/note/delete/118627/in+docs Del: other reasons-- https://master.php.net/note/delete/118627 Reject -- https://master.php.net/note/reject/118627 Search -- https://master.php.net/manage/user-notes.php
