如何在laravel中创建文件夹之前检查文件夹是否存在？

Question

I need to know if a folder exists before creating it, this is because I store pictures inside and I fear that the pictures are deleted if overwrite the folder. The code I have to create a folder is as follows

$path = public_path().'/images';
File::makeDirectory($path, $mode = 0777, true, true);

how can I do it?

Answer 1

See: file_exists()

Usage:

if (!file_exists($path)) {
    // path does not exist
}

In Laravel:

if(!File::exists($path)) {
    // path does not exist
}

Note: In Laravel $path start from public folder, so if you want to check 'public/assets' folder the $path = 'assets'

Answer 2

With Laravel you can use:

$path = public_path().'/images';
File::isDirectory($path) or File::makeDirectory($path, 0777, true, true);

By the way, you can also put subfolders as argument in a Laravel path helper function, just like this:

$path = public_path('images/');

Answer 3

You can also call this method of File facade:

File::ensureDirectoryExists('/path/to/your/folder')

which creates a folder if it does not exist and if exists, then does nothing

Answer 4

In Laravel 5.x/6 you can do it with Storage Facade :

use Illuminate\Support\Facades\Storage;

$path = "path/to/folder/";

if(!Storage::exists($path)){
    Storage::makeDirectory($path);
}

Way -1 :

if(!is_dir($backupLoc)) {

    mkdir($backupLoc, 0755, true);
}

Way -2 :

if (!file_exists($backupLoc)) {

    mkdir($backupLoc, 0755, true);
}

Way -3 :

if(!File::exists($backupLoc)) {

    File::makeDirectory($backupLoc, 0755, true, true);
}

Do not forget to use use Illuminate\Support\Facades\File;

Way -4 :

if(!File::exists($backupLoc)) {

    Storage::makeDirectory($backupLoc, 0755, true, true);
}

In this way you have to put the configuration first in config folder filesystems.php . [Not recommended unless you are using external disks]

Answer 6

The recommended way is to use

if (!File::exists($path))
{

}

See the source code

If you look at the code, it's calling file_exists()

Answer 7

I normally create random folders inside the images for each file this helps a bit in encrypting urls and thus public will find it hardr to view your files by simply typing the url to your directory.

// Check if Logo is uploaded and file in random folder name -  
if (Input::hasFile('whatever_logo'))
            {
                $destinationPath = 'uploads/images/' .str_random(8).'/';
                $file = Input::file('whatever_logo');
                $filename = $file->getClientOriginalName();                
                $file->move($destinationPath, $filename);
                $savedPath = $destinationPath . $filename;
                $this->whatever->logo = $savedPath;
                $this->whatever->save();
            }

            // otherwise NULL the logo field in DB table.
            else 
            {
                $this->whatever->logo = NULL;    
                $this->whatever->save();    
            }

This is what works great for me

if(!File::exists($storageDir)){
    File::makeDirectory($storageDir, 0755, true, true);
    $img->save('Filename.'.png',90);
}
