note 81269 added to function.fwrite

Some people say that when writing to a socket not all of the bytes requested to be written may be written. You may have to call fwrite again to write bytes that were not written the first time. (At least this is how the write() system call in UNIX works.) This is helpful code (warning: not tested with multi-byte character sets) function fwrite_with_retry($sock, &$data) { $bytes_to_write = strlen($data); $bytes_written = 0; while ( $bytes_written < $bytes_to_write ) { if ( $bytes_written == 0 ) { $rv = fwrite($sock, $data); } else { $rv = fwrite($sock, substr($data, $bytes_written)); } if ( $rv === false || $rv == 0 ) return( $bytes_written == 0 ? false : $bytes_written ); $bytes_written += $rv; } return $bytes_written; } Call this like so: $rv = fwrite_with_retry($sock, $request_string); if ( ! $rv ) die("unable to write request_string to socket"); if ( $rv != strlen($request_string) ) die("sort write to socket on writing request_string"); ---- Server IP: 209.41.74.194 Probable Submitter: 12.226.111.244 ---- Manual Page -- http://www.php.net/manual/en/function.fwrite.php Edit -- https://master.php.net/note/edit/81269 Del: integrated -- https://master.php.net/note/delete/81269/integrated Del: useless -- https://master.php.net/note/delete/81269/useless Del: bad code -- https://master.php.net/note/delete/81269/bad+code Del: spam -- https://master.php.net/note/delete/81269/spam Del: non-english -- https://master.php.net/note/delete/81269/non-english Del: in docs -- https://master.php.net/note/delete/81269/in+docs Del: other reasons-- https://master.php.net/note/delete/81269 Reject -- https://master.php.net/note/reject/81269 Search -- https://master.php.net/manage/user-notes.php
