Listing files using wildcards with Laravel Storage and AWS S3

Question

I am converting a Laravel (5.3) app to use AWS S3 as image storage. I need to programmatically get list of images whose names comply with a specific mask (eg 'FS_1054_*.JPG') which when I used local storage I could do easily with the glob() function.

Any suggestions as to how I could do this with S3?

Solution 1

Suppose If you want to get all files then you can use this

Storage::disk('s3')->allFiles('');

It will return All file that have in your bucket. but if you want to look particular then

Storage::disk('s3')->allFiles('FolderName'); 

or

Storage::disk('s3')->allFiles('FolderName/2FolderName');

have a look of this image. when you want to look all files.

Solution 2

$storage = Storage::disk('s3');
$client = $storage->getAdapter()->getClient();
$command = $client->getCommand('ListObjects');
$command['Bucket'] = $storage->getAdapter()->getBucket();
$command['Prefix'] = 'path/to/FS_1054_';
$result = $client->execute($command);
foreach ($result['Contents'] as $file) {
    //do something with $file['Key']
}

I have found an answer, though am happy to know if there is a better one.

Use Storage::files(folder_name) to list all files in the folder, this returns an array. Then use array_where and starts_with to filter the list:

$files = Storage::files(folder_name);

$files = array_where($files, function ($value, $key) use ($mask) {
   return starts_with(basename($value), $mask);
});
