Please mention this 8192 default length in document, and also i hope there could be a -1 value for

Yes, I am still interested in this. It wouldn't let me re-open the bug.

Yes, this would still be useful to me. I've had to work around it in the meantime. Thanks for

Description:
------------
I believe stream_get_line() should allow the $length parameter to be optional by allowing a $length
of -1 that would read the remaining buffer up to either the $ending delimiter or EOF.
Currently if you pass a $length of 0, the $length defaults to PHP_SOCK_CHUNK_SIZE (8192) in
ext/standard/streamsfuncs.c. If you pass a length of -1, a PHP Warning is generated.
Other 'similar' functions that allow length to be optional or -1 are fgets,
stream_get_contents, and file_get_contents.
Also, the manual page for stream_get_line() states that this function is the same fgets() except for
the handling of the delimiter - but another difference, at least right now, is that the $length
parameter is required in stream_get_line(), but optional in fgets().
Reproduce code:
---------------
<?php
$fp = tmpfile();
fwrite($fp, str_repeat('a', 10000));
fseek($fp, 0);
echo strlen(stream_get_line($fp, 0));
fseek($fp, 0);
echo strlen(stream_get_line($fp, -1));
fclose($fp);
Expected result:
----------------
8192
10000
Actual result:
--------------
8192
Warning: stream_get_line(): The maximum allowed length must be greater than or equal to zero
