Zamzar PHP

@zamzar on Twitter Total Downloads Apache 2 License

The Zamzar PHP library provides convenient access to the Zamzar API from applications written in the PHP language. It includes a pre-defined set of classes which make it easy to submit files for conversion, retrieve converted files and utilise all of the features that the API offers.

Jump to:


  • Before you begin, signup for a Zamzar API Account or retrieve your existing API Key from the Zamzar Developers Homepage
  • PHP 7.2.34 and later.


You can install the bindings via Composer. Run the following command:

composer require zamzar/zamzar-php

To use the bindings, use Composer's autoload:


If you do not wish to use Composer, you can download the latest release. Then, to use the bindings, include the init.php file.



The bindings require the following extensions in order to work properly:

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Initialise the Zamzar Client

To initialise the client, declare a new ZamzarClient which accepts a string or config array:

// Connect to the Production API using an API Key
$zamzar = new \Zamzar\ZamzarClient('apikey');

To specify whether the client using the Production or Test API, use a Config array:

// Use the Production API
$zamzar = new \Zamzar\ZamzarClient([
    'api_key' => 'apiKey',
    'environment' => 'production'

// Use the Sandbox API
$zamzar = new \Zamzar\ZamzarClient([
    'api_key' => 'apiKey',
    'environment' => 'sandbox'

Test the Connection

To confirm your credentials are correct, test the connection to the API which will return a welcome message and confirm which API you are using (Production or Test).

echo $zamzar->testConnection();

Typical Usage

The most common requirement is to submit a job to convert a file, wait for the job to complete, download the converted files and delete the files on Zamzar servers.

// Submit the file
$job = $zamzar->jobs->create([
    'source_file' => 'path/to/local/file',
    'target_format' => 'xxx'

// Wait for the job to complete (the default timeout is 60 seconds)

// Download the converted files 

// Delete the source and target files on Zamzar's servers

The above use case might be applied when other things are happening in between each step, but if not, and you want to chain the whole thing together:

// Do the whole thing together
$job = $zamzar->jobs->create([
        'source_file' => 'path/to/localfile', 
        'target_format' => 'pdf'

Configure a Logger

The library does minimal logging, if the debug config option is used. Use either the supplied default logger or a psr-3 compatible logger.

$client = new Zamzar\ZamzarClient([
    'api_key' = '****',
    'debug' => true,

// PSR-3 Compatible Logger

// Using Monolog
$logger = new Logger('Zamzar');
$logger->pushHandler(new StreamHandler(__DIR__.'/app.log', Logger::DEBUG));


We would greatly value feedback and contributions from our community.

To run tests:

  • Ensure dependencies are installed using composer install

  • Specify your API Key within an environment variable ZAMZAR_API_KEY

  • Run ./vendor/bin/phpunit tests
