Filestack PHP

This is the official PHP SDK for Filestack - API and content management system that makes it easy to add powerful file uploading and transformation capabilities to any web or mobile application.

Requirements

• PHP 8.3+

Resources

• Filestack
• Documentation

Installing

Install filestack with composer, either run

$ composer require --prefer-dist filestack/filestack-php

Usage

Filestack library gives you access to three useful classes:

• FilestackClient - for easy file upload (creates Filelink objects)
• Filelink - for file handling (downloading, converting etc.)
• FileSecurity - for applying policy and signature values to your API calls

Uploading files

First, you need to create an instance of FilestackClient

use Filestack\FilestackClient;

$client = new FilestackClient('YOUR_API_KEY');

Call the upload() function

$filelink = $client->upload('/path/to/file');

Storage

Amazon S3 is used to store your files by default. If you wish to use a different one, you can pass in additional parameter 'location' when making upload() and store calls

$client = new FilestackClient('YOUR_API_KEY');
$extras = [
    'Location' => 'dropbox',
    'Filename' => 'somefilename.jpg',
];

$filepath = '/path/to/file';
$filelink = $client->upload($filepath);

# get metadata of file
$metadata = $client->getMetaData($filelink->handle, $fields);

# get content of a file
$content = $client->getContent($filelink->handle);

# download a file
$destination = '/path/to/file';
$result = $client->download($filelink->handle, $destination);

# overwrite a file
$filelink2 = $client->overwrite('/path/to/file', $filelink->handle);

Manipulating files

Filelink objects can be created in two ways:

• by uploading a file using FilestackClient
• by initializing Filelink with file handle and api_key

First method was shown above, the second method is also very easy and will create objects representing files that were already uploaded.

use Filestack\filelink;

$filelink = new Filelink('some-file-handle', 'YOUR_API_KEY');

# transforming an image
$transformed_filelink = $filelink
            ->circle()
            ->blur(['amount' => '20'])
            ->save();

# get metadata
$metadata = $filelink->getMetaData();

# get content of a file
$content = $filelink->getContent();

$filepath = '/path/to/file';

# download a file
$filelink->download($filepath);

# overwrite remote file with local file
$filelink->overwrite($filepath);

# delete remote file
$filelink->delete();

Tagging files and detecting safe for work content

use Filestack\FilestackClient;
use Filestack\FilestackSecurity;

$security = new FilestackSecurity('YOUR_SECURITY_SECRET');
$client = new FilestackClient('YOUR_API_KEY', $security);

$file_handle = 'some-file-handle';

# get tags with client
$result_json = $client->getTags($file_handle);

# get tags with filelink
$filelink = new Filelink($file_handle, 'YOUR_API_KEY', $security);

$json_result = $filelink->getTags();

# get safe for work flag with client
$result_json = $client->getSafeForWork($file_handle);

# get safe for work flag with filelink
$json_result = $filelink->getSafeForWork();

For more examples, see the examples/ folder in this project.

Intelligent Ingestion

The Intelligent Ingestion feature allows user to upload a file in chunks of not precised size. This creates a more stable upload flow that ensures the file being uploaded will eventually complete successfully, regardless of network latency or timeout errors.

However, the upload process may be slower than the normal upload flow for large files, as there are errors are retried using the exponential backoff retry strategy.

Lastly, this feature has to be turned on for the apikey being used. To turn on this feature please contact Filestack at support@filestack.com.

$client = new FilestackClient('YOUR_API_KEY');
$filelink = $client->upload('/path/to/file', ['intelligent' => true]);
