Actually, according to the docs here: http://us2.php.net/manual/en/function.stream-get-meta-data.php It does not tell you that, it says: unread_bytes (int) - the number of bytes currently contained in the read buffer. Nothing about it shouldn't be used. Infact in the comments on the page, they talk about a work around in PHP 4.x. Could you please update the Documentation then to say this? Along with any other varables that function returns that shouldn't be used? Thanks Previous Comments: ------------------------------------------------------------------------ [2004-11-09 17:06:01] [EMAIL PROTECTED] 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. ------------------------------------------------------------------------ [2004-11-09 15:52:42] kormoc at gmail dot com 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 [EMAIL PROTECTED] ~ $ php streamtest.php NOTICE AUTH :*** Looking up your hostname...
