Question

我已包含文件类型，请检查以下代码。如果我从允许的类型中选择2个文件，从不允许的类型中选择一个文件，则代码仍会保存允许的一个，并显示文件类型的msg。我想如果文件不是允许的文件，则代码不应保存任何内容。

使用以下代码检查图像大小，类型，错误，

$file_ext=strtolower(end(explode('.',$_FILES['file_array']['name'])));

  $extensions= array("jpeg","jpg","png");

if(in_array($file_ext,$extensions)=== false){
        $errors[]="extension not allowed, please choose a JPEG or PNG file.";
 }

 if($file_size > 2097152){ // set whatever max size you want
       $errors[]='File size must be excately 2 MB';
 }

 if(empty($errors)==true){
       move_uploaded_file($file_tmp,"images/".$file_name);
       echo "Success";
 }else{
      print_r($errors);
 }
