Read a .csv file into an array in Laravel

问题:

I have stored a .csv file in this directory in Laravel 5 :

/storage/app/data.csv

Inside of this function I am trying to read the contents of this file and extract a few columns from it, like name and city to an array, sample code:

use Illuminate\Support\Facades\Storage;

public function get_data() {

 $file_n = Storage::url('data.csv');
 $file = fopen($file_n, "r");
 $all_data = array();
 while ( ($data = fgetcsv($file, 200, ",")) !==FALSE {

     $name = $data[0];
     $city = $data[1];
     $all_data = $name. " ".$city;

     array_push($array, $all_data);
  }
  fclose($file);
}

I am getting an ErrorException in Controller:

fopen(/storage/data.csv): failed to open stream: No such file or directory

But the file is there. Is there a better way to do this instead?

Thanks for looking!

回答1:

Your issue is with the path as previous people pointed out.

You can use the helper function storage_path https://laravel.com/docs/5.3/helpers#method-storage-path

In your case it will be used like this:

storage_path('app/data.csv');

As a recomendation you can use this libary to work with CSV/Excel files, it's pretty easy to use: https://github.com/Maatwebsite/Laravel-Excel

Laravel 5.7 try this :

Storage::disk('local')->path('import.csv');

It should be good.

I figured it out by using "storage_path".

...
$filename = storage_path('/app/data.csv');
$file = fopen($filename, "r");
$all_data = array();
while ( ($data = fgetcsv($file, 200, ",")) !==FALSE ) {
    ...
}

Thanks!

I solved this issue by adding a url key to my local disk config in config/filesystems.php like so:

    'local' => [
        'driver' => 'local',
        'root' => storage_path('app'),
        'url' => storage_path('app')
    ],

Now I can reference Storage::url('filename.txt') and it returns:

    /home/josh/apps/storage/app/filename.txt

Try the below

$file_n = Storage::get('data.csv');
