(PHP 4 >= 4.2.0, PHP 5 <= 5.0.5, PHP 7) Writes data to fd with optional truncation at length int dio_write ( resource $fd, string $data [, int $len = 0 ] ) dio_write() writes up to len bytes from data to file fd. Parameters: fd The file descriptor returned by dio_open(). data The written data. len

(PHP 4 >= 4.2.0, PHP 5 <= 5.0.5, PHP 7) Truncates file descriptor fd to offset bytes bool dio_truncate ( resource $fd, int $offset ) dio_truncate() truncates a file to at most offset bytes in size. If the file previously was larger than this size, the extra data is lost. If the file previously was shorter, it is unspecified whether the file is left unchanged or is extended. In the latter case the extended part read
