New Comment:
unread_bytes refers to the number of bytes in PHP's own internal
buffer.
You should not use this value in a script, as is stated in the
documentation.

Description:
------------
For a stream in blocking or non blocking mode, stream_get_meta_data
does not return the correct number of unread bytes until it's been
'freshened' by a fread or similar.
For example, the test program.
The unread bytes will be 0, but if you insert a fgets($fp) above the
stream_get_meta_data line, it will return the correct number of bytes.
It also does this if blocking is set to false.
If you need any more information about my setup, feel free to ask, it's
really not that odd or special.
Thanks!
Reproduce code:
---------------
<?PHP
$fp=fsockopen("irc.freenode.net",6667);
stream_set_blocking($fp,TRUE);
fwrite($fp,"NICK BOOT\nUSER BOOT 0 * :BOOT\n\n");
$read=array($fp);
while(1) {
if(false===($num_changed_streams=stream_select($read,$write=NULL,$except=NULL,1)))
break;
else {
$data=stream_get_meta_data($fp);
print_r($data);
while($data['unread_bytes']>0) {
echo fgets($fp);
$data=stream_get_meta_data($fp);
}
}
}
fclose($fp);
?>
Expected result:
----------------
Something similar to this
