 public function destroy($id) {
    $news = News::findOrFail($id);
    $image_path = app_path("images/news/{$news->photo}");

    if (File::exists($image_path)) {

You could use PHP's unlink() method just as @Khan suggested.

您可以按照@Khan 的建议使用 PHP 的 unlink() 方法。

But if you want to do it the Laravel way, use the File::delete() method instead.

但是如果你想用 Laravel 的方式来做，请改用 File::delete() 方法。

// Delete a single file

//删除单个文件

File::delete($filename);

// Delete multiple files

// 删除多个文件

File::delete($file1, $file2, $file3);

// Delete an array of files

// 删除一组文件

$files = array($file1, $file2);
File::delete($files);

And don't forget to add at the top:

并且不要忘记在顶部添加：

use Illuminate\Support\Facades\File;

Use the unlinkfunction of php, just pass exact path to your file to unlink function :

使用php的unlink功能，只需将文件的确切路径传递给 unlink 功能：

unlink($file_path);

Do not forget to create complete path of your file if it is not stored in the DB. e.g

如果文件未存储在数据库中，请不要忘记创建文件的完整路径。例如

$file_path = app_path().'/images/news/'.$news->photo;

this method worked for me
First, put the line below at the beginning of your controller:

这种方法对我
有用首先，将下面的行放在控制器的开头：

use File;

below namespace in your php file Second:

在您的 php 文件中的命名空间下方第二个：

 $destinationPath = 'your_path';
 File::delete($destinationPath.'/your_file');

$destinationPath --> the folder inside folder public.

$destinationPath --> public 文件夹中的文件夹。

First, you should go to config/filesystems.phpand set 'root' => public_path()like so:

首先，你应该像这样去config/filesystems.php设置'root' => public_path()：

'disks' => [

    'local' => [
        'driver' => 'local',
        'root' => public_path(),
],

Then, you can use Storage::delete($filename);

然后，您可以使用 Storage::delete($filename);

Try to use:

尝试使用：

unlink('.'.Storage::url($news->photo));

Look the dotand concatenationbefore the call of facade Storage.

在调用门面存储之前查看点和连接。

Using PHP unlink()function, will have the file deleted

使用PHPunlink()函数，将文件删除

$path = public_path()."/uploads/".$from_db->image_name;
unlink($path);

The above will delete an image returned by $from_db->image_namelocated at public/uploadsfolder

以上将删除$from_db->image_name位于public/uploads文件夹中返回的图像

试试看：Laravel 5.5

public function destroy($id){  
      $data = User::FindOrFail($id);  
      if(file_exists('backend_assets/uploads/userPhoto/'.$data->photo) AND !empty($data->photo)){ 
            unlink('backend_assets/uploads/userPhoto/'.$data->photo);
         } 
            try{

                $data->delete();
                $bug = 0;
            }
            catch(\Exception $e){
                $bug = $e->errorInfo[1];
            } 
            if($bug==0){
                echo "success";
            }else{

the easiest way for you to delete the image of the news is using the model event like below and the model delete the image if the news deleted

您删除新闻图像的最简单方法是使用如下所示的模型事件，如果新闻删除，模型将删除图像

at first you should import this in top of the model class use Illuminate\Support\Facades\Storageafter that in the model class Newsyou should do this

首先你应该在模型类的顶部导入它，use Illuminate\Support\Facades\Storage然后在模型类中News你应该这样做

public static function boot(){
    parent::boot();

    static::deleting(function ($news) {
          Storage::disk('public')->delete("{$news->image}");
    })
}

or you can delete the image in your controller with this command

或者您可以使用此命令删除控制器中的图像

Storage::disk('public')->delete("images/news/{$news->file_name}");

but you should know that the default disk is public but if you create folder in the public folder and put the image on that you should set the folder name before $news->file_name

但是你应该知道默认磁盘是公共的，但是如果你在公共文件夹中创建文件夹并将图像放在上面你应该在之前设置文件夹名称 $news->file_name

First make sure the file exist by building the path

首先通过构建路径确保文件存在

if($request->hasFile('image')){
    $path = storage_path('app/public').'/YOUR_FOLDER/'.$db->image;
      if(File::exists($path)){
          unlink($path);
      }
