Question

我的问题是如何动态添加图片扩展名。所以当时用户更新其配置文件，它可以显示所有图像类型，如jpg png或 jpeg。我知道我使用png但不知道如何动态添加扩展。还请告诉我如何让照片独一无二如果用户上传他的下一个个人资料图片，则可能无法覆盖旧的。

   <img src="uploads/profile/profile'.$_SESSION['iduser'].'.png" class="img-
    responsive "img-circle"  alt="User Image" >  


   $files = $_FILES['uploadphoto'];
   $fileName = $_FILES['uploadphoto']['name'];
   $fileTmpName= $_FILES['uploadphoto']['tmp_name'];
   $fileSize =$_FILES['uploadphoto']['size'];
   $fileError =$_FILES['uploadphoto']['error'];
   $fileType =$_FILES['uploadphoto']['type'];
   $fileExt = explode('.',$fileName);
   $fileActualExt =strtolower(end($fileExt));
   if($fileType ='jpg' && $fileType ='png' && $fileType ='jpeg'){
   if($fileError === 0){
   if($fileSize < 5000000){
   $fileNewName = "profile".$id.".".$fileActualExt;
   $fileDestination ="uploads/profile/".$fileNewName;
   move_uploaded_file($fileTmpName,$fileDestination);
   $sqlImg = "UPDATE profilestatus SET status =0 WHERE iduser = '$id'";
   mysqli_query($conn,$sqlImg);
   }else{
        echo "Your file is to big to upload!";
        }
   }else{
        echo "There is an error!";
        }
  }
   else{
       echo "Photo cannot be uploaded! image is not of the type jpg png or 
       jpeg";
       }
