1. Load in the controller interface
use yii\web\UploadedFile;
$file = UploadedFile::getInstanceByName('photo');
//保存路径
$path = 'images/';
//判断文件是否存在
if(!file_exists($path)){
mkdir($path);
}
//重命名文件名
$file_name = date('Y-m-d').mt_rand(0000,9999).'.'.$file;
$new_path= $path.$file_name;
$file->saveAs($new_path,true);The above introduces Yii20 file upload, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
