Bug description: echo and print not filtered when stream filter installed on
php://output..
Description:
------------
print and echo are not filtered when a stream filter is installed on
php://output.
Whilst there are workarounds they are either not as flexible (using
output_handler) or not as convenient (changing all my echos to fwrites) as
the filter pattern.
Would argue that if this behaviour is by design then the design should be
changed or at the very least the documentation amended to reflect this
situation.
Reproduce code:
---------------
class strtoupper_filter extends php_user_filter
{
function filter($in, $out, &$consumed, $closing)
{
while ($bucket = stream_bucket_make_writeable($in)) {
$bucket->data = strtoupper($bucket->data);
$consumed += $bucket->datalen;
stream_bucket_append($out, $bucket);
}
return PSFS_PASS_ON;
}
}
stream_filter_register("strtoupper", "strtoupper_filter");
$fp = fopen("php://output", "w");
stream_filter_append($fp, "strtoupper");
echo "echo: testing 123<br>";
print("print: testing 123<br>");
fwrite($fp, "fwrite: testing 123<br>");
Expected result:
----------------
ECHO: TESTING 123
PRINT: TESTING 123
FWRITE: TESTING 123
Actual result:
--------------
echo: testing 123
print: testing 123
FWRITE: TESTING 123
