SirvPHP Client

This library is a Sirv S3 Client written in PHP. It is a port of the official SDK released by Sirv with a few modifications, and rebuilt as a Composer package.

---

Installation:

The easiest way to install the client is using Composer:

$ composer require benmajor/sirv-s3-client

Since there are no external dependencies (other than PHP >= 5.4 and with the cURL module installed), you can also download the single PHP class from the src directory and include it in your code using PHP's require statement:

require '/path/to/SirvS3Client.php;

---

Usage:

This client provides some utility functions to easily work with the Sirv S3 buckets and upload content directly from your project using PHP. Usage and function reference is as follows:

1. Creating the client:

We must first create a client before using any of the functions. This is done easily by instantiating the class using your Sirv S3 Bucket, S3 Key and S3 Secret (all of which are located in your Settings page) as follows:

# Include Composer autoloader:
require 'vendor/autoload.php';

use BenMajor\SirvPHP\SirvS3Client;

$client = new SirvS3Client(
  'SIRV_S3_BUCKET',
  'SIRV_S3_KEY',
  'SIRV_S3_SECRET'
);

Once the client has been instantiated, you can check the connection is valid and live using the testConnection() method:

if( $client->testConnection() ) {
  # Connection is valid and ready.
} else {
  # Something went wrong with the connection.
}

2. Check if resource exists:

To check if a folder exists within the Bucket, simply use checkIfObjectExists() by passing a relative folder path to the method. The method returns true if the folder exists, or false if not:

$client->checkIfObjectExists('/example/folder');

It's also possible to check if a specific file exists within a folder by passing the basename of the file (including extension) as a second parameter to the checkIfObjectExists method:

$client->checkIfObjectExists('example/folder', 'image.jpg');

Returns true if the resource exists, otherwise false.

3. Get a list of resources:

To get a list of resources (i.e. folders and files) that exist, use the getBucketContents() method:

$client->getBucketContents('example/folder');

Note that we have specified a folder path above to retrieve only resources that exist within the example/folder directory. The method can also be called with no parameter to retrieve the contents of the Bucket's root.

This method returns an object as follows:

{
  "bucket": "BUCKET_NAME",
  "current_dir": "CURRENT_WORKING_DIRECTORY",
  "contents": [ ],
  "dirs": [ ]
}

4. Creating folders:

To create a new folder, simply use the createFolder() method and pass the relative path to the folder to be created as the first argument:

$client->createFolder('example/new-folder');

Returns true if the folder was successfully created, otherwise false.

5. Uploading files:

Files can be easily uploaded using the uploadFile() method. The first parameter is the destination folder and filename to which the file should be uploaded. The second parameter must contain a relative path to a file that already exists on the server (it can also be a reference to the temporary file created following a file upload).

Two examples are given below; one using a file that already exists, and another of uploading a user-uploaded file from PHP's temporary directory.

Upload existing file on server:

$client->uploadFile(
  'example/folder/my-picture.jpg',
  '/path/to/local/my-picture.jpg'
);

Uploading a temporary file:

$client->uploadFile(
  'example/folder/'.basename($_FILES['uploaded']['name']),
  $_FILES['uploaded']['TMP_NAME']
);

6. Downloading files:

The getFile() method can be used to retrieve the raw contents of a file from the Bucket. The string can then be used to create a file on the local filesystem (using file_put_contents() or similar). If the file does not exist on the S3 Bucket, or fails for another reason, the method returns an empty string, so it is advisable to check the returned value before using it:

$file = $client->getFile('/path/to/file.jpg');

if( ! empty($file) ) {
  file_put_contents('file.jpg', $file);
}

7. Copying files:

Sometimes, we may wish to copy a file from one directory to another within the Bucket. To do this, use the copyFile() method. The first paramater is the path of the source file, and the second parameter is its destination:

$client->copyFile(
  'path/to/image.jpg',
  'another/path/image.jpg'
);

Files can also be copied to the same directory, but must be renamed:

$client->copyFile(
	'path/to/image.jpg',
	'path/to/image-copy.jpg'
);

8. Renaming files:

It is sometimes necessary to rename a file within the Bucket. This can be done using the renameFile() method, and passing the relative path as the first parameter:

$client->renameFile(
  'example/folder/image.jpg',
  'example/folder/renamed.jpg'
);

9. Deleting files:

The deleteFile() method can be used to delete files from the Bucket instance. The relative path of the resource to be deleted should be passed as the first parameter of this method.

$client->deleteFile('example/folder/image.jpg');

Credits:

The package is heavily based on the official SDK released by Sirv, which itself is a simplified version of the AWS PHP SDK.
