note 29343 added to function.fopen

When I want to write to a file at the beginning of it, I can use "r+" or "w+", but in both cases, file I write to will loose some("r+") or all old information("w+"). How can I prevent this, by not usig "a+" [I want to put the new information before the old information]? -- http://www.php.net/manual/en/function.fopen.php http://master.php.net/manage/user-notes.php?action=edit+29343 http://master.php.net/manage/user-notes.php?action=delete+29343 http://master.php.net/manage/user-notes.php?action=reject+29343
