删除3天以前的日志文件,Fatal error
我不懂PHP,现在想实现一个功能,删除指定目录中三天以前的文件(日志),就在百度上找的一个删除目录的函数,如下

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->    function del_directory($dir){        if(!($mydir = @dir($dir))){            return;        }        while($file = $mydir->read()){            if(is_dir("$dir$file") && $file!='.' && $file!='..'){                @chmod("$dir$file", 0777);                del_dir("$dir$file");            }elseif(is_file("$dir/$file")){                [email protected]($file);//读取文件的最后更新时间                if(time() - $file_time > 3600 * 24 * 3){                    @chmod("$dir/$file", 0777);                    @unlink("$dir/$file");                }            }        }        $mydir->close();        @chmod($dir, 0777);        @rmdir($dir);    }

报错:Fatal error: Unsupported operand types in D:\wamp\www\Player\playlogviewer.php on line 36
对应的是这一行代码:if(time() - $file_time > 3600 * 24 * 3)

麻烦看看是什么问题,谢谢!
