代码如下，求大神指点：
$allowext=array(‘jpeg’,’pjpeg’,’jpg’,’png’,’gif’,’zip’);
$ext=pathinfo($fileinfo[‘name’],pathinfo_extension);
if(!in_array($ext, $allowext)){
exit(‘非法文件类型’);
}
php.ini中：extension=php_zip.dll
问题在哪呢？？？

楼主完成了么？最近也有个这个需求，不熟悉php，楼主有demo么？跪求帮助啊
没看懂.是上传文件.不管txt,zip,jpg..还是解压zip上传.
前端上传

//@param options 一系列可选的key/value参数的集合:

//url string 上传文件服务器端url

//progress function 进度回调函数.原型为:function(obj, process, total);
