Google Cloud Storage Meta Bucket for PHP

A simple GCP storage bucket wrapper to automatically set metadata on uploaded files.

Metadata reference: https://cloud.google.com/storage/docs/metadata

Created for use with other libraries that may not allow you to configure the metadata (eg Cache-Control) for storage bucket objects.

Works with:

• https://github.com/1up-lab/OneupFlysystemBundle
• https://github.com/dustin10/VichUploaderBundle (using Flysystem)
• https://github.com/liip/LiipImagineBundle (using Flysystem)

Installation

Requires: https://github.com/googleapis/google-cloud-php-storage

To begin, install the preferred dependency manager for PHP, Composer.

Install the wrapper:

$ composer require techdyn/google-storage-meta-bucket

Sample

require 'vendor/autoload.php';

use TechDyn\GoogleStorageMetaBucket\Storage\ProxyStorageClient;

$storage = new ProxyStorageClient(); // ProxyStorageClient extends Google\Cloud\Storage\StorageClient;

$bucket = $storage->bucket('my_bucket'); // MetaBucket extends Google\Cloud\Storage\Bucket

// https://cloud.google.com/storage/docs/metadata
$bucket->setOption('cacheControl', 'no-cache, max-age=60'); // $name uses metadata field written as camelCase

// Upload a file to the bucket.
$bucket->upload(
    fopen('/data/file.txt', 'r')
);
