使用方法:

引用

$upload = new FilesUpload(); $upload ->dst_path = $uploadpath;
$upload -> send($_FILES[upfile]);
var_dump ($upload -> reinfo);

这里我补充下.. 这个函数会对上传的各个环节进行检测如果有其中的任意出问题..
会直接反应在 FilesUpload::errver 上..
并且在文件名命名的地方我用了eval 动态执行函数.. 这样就可以再类初始化的时候初始化上传保存文件名的命名规则
另外可以设置上传大小显示以及配置上传类型限制
以下我做个示范..
比如上面的使用方法

引用

$upload = new FilesUpload();
$upload->dst_name = 'MD5(time()).\'.\'.$Files[\'type\'];'; //从新定义命名规则,用时间戳的MD5值对上传文件进行命名
$upload -> maxsize(500); //显示批量上传的总大小限制为500KB (如果大家想用字节单位请直接用FilesUpload::maxsize属性)
$upload ->dst_path = './upload/'; //设置上传文件保存的目录
$upload ->sux = array ('gif', 'jpg', 'png'); //从新设置允许的上传文件类型这里限制为仅限图片上传
$upload -> send($_FILES[upfile]); //开始处理上传
var_dump ($upload -> reinfo);
