php代码
//php layui图片上传 publicfunctionupload_img(){ $file= request()->file('file'); // 获取上传的文件 if($file==null){ exit(json_encode(array('code'=>1,'msg'=>'未上传图片'))); }else{ //5、对上传文件做出条件限制（类型，大小等） $map= [ 'ext'=>'jpg,png,gif,jpeg',//后辍名 'size'=>320000000,//最大3M ]; //6、对上传的文件进行较验，如果合格就进行转移到预定设定好的public/uploads目录下 //返回保存的文件信息info，包括文件名和大小等数据 $info= $file->validate($map)->move(ROOT_PATH .
