Send and receive faxes in PHP with the InterFAX REST API.
Two versions of this library exist, 1.x and 2.x. The 1.x version provides support for older versions of PHP, whilst the 2.x branch is designed to support the more recent releases of the language:
| Package Version | Minimum PHP Version | Maximum PHP Version |
|---|---|---|
| 1.x | 5.6 | 7.2 |
| 2.x | 7.3 | 8.1 |
The preferred method of installation is via Packagist and Composer. Run the following command to install the package and add it as a requirement to your project's composer.json:
composer require interfax/interfaxwith 1.x version constraint
composer require interfax/interfax:"^1"or with 2.x version constraint
composer require interfax/interfax:"^2"You can download the package in its entirety (from 1.0.2 onward). The Releases page lists all stable versions. Download any file
with the name interFAX-PHP-[RELEASE_NAME].zip for a package including this library and its dependencies.
Uncompress the zip file you download, and include the autoloader in your project:
require_once '/path/to/interFAX-PHP-[RELEASE_NAME]/vendor/autoload.php';You may wish to rename the release folder to not include the RELEASE_NAME, so that you can drop in future versions without changing the include.
The installation docs explain how to create a standalone installation.
To send a fax for a pdf file:
use Interfax\Client;
$interfax = new Client(['username' => 'username', 'password' => 'password']);
$fax = $interfax->deliver(['faxNumber' => '+11111111112', 'file' => 'folder/file.pdf']);
// get the latest status:
$fax->refresh()->status; // Pending if < 0. Error if > 0
// Simple polling
while ($fax->refresh()->status < 0) {
sleep(5);
}Client | Account | Outbound | Inbound | Documents | Helper Classes | Query Parameters | Exceptions
The client follows the 12-factor apps principle and can be either set directly or via environment variables.
$client = new Interfax\Client(['username' => '...', 'password' => '...']);
// Alternative: will utilise environment variables:
// * INTERFAX_USERNAME
// * INTERFAX_PASSWORD
$client = new Interfax\Client();To send a fax, call the deliver method on the client with the appropriate array of parameters.
$client = new Interfax\Client(['username' => '...', 'password' => '...']);
$fax = $client->deliver([
'faxNumber' => '+442086090368',
'file' => __DIR__ . '/../tests/Interfax/test.pdf'
]);The deliver method will take either a file or files argument. The files is an array of file values.
Each file entry can be:
- local path - if the file is larger than the allowed limit, it will be automatically uploaded as an
Interfax\Document - uri (from an
Interfax\Document) - an array defining a streamed resource (see below)
Interfax\FileInterfax\Document
Because of the high degree of flexibility that PHP stream resources offer, it's not practical to retrieve information automatically from a stream to send as a fax. As such, there are certain required parameters that must be provided:
$stream = fopen('/tmp/fax.pdf', 'rb');
$fax = $client->deliver([
'faxNumber' => '+442086090368',
'file' => [$stream, ['name' => 'fax.pdf', 'mime_type' => 'application/pdf']]Note that it is assumed that the stream will not exceed the file size limitation for an inline file to be sent. However, if a size parameter is provided for the stream, and this exceeds the limit, it will be automatically uploaded as a Interfax\Document
Determine the remaining faxing credits in your account.

Get list | Get completed list | Get record | Get image | Cancel fax | Search | Resend fax
Interfax\Client has an outbound property that can be accessed:
$outbound = $client->outbound;$faxes = $client->outbound->recent();
// Interfax\Outbound\Fax[]Options: limit, lastId, sortOrder, userId
$fax_ids = [ ... ]; // array of fax ids
$client->outbound->completed($fax_ids);
// Interfax\Outbound\Fax[]$client->outbound->find(fax_id)
Retrieves information regarding a previously-submitted fax, including its current status.
$fax = $client->outbound->find(123456);
//Interfax\Outbound\Fax || null$client->outbound->find(fax_id)->image()
The image is retrieved via a method on the outbound fax image object.
$fax = $client->outbound->find(123456);
if ($fax) {
$image = $fax->image();
$image->save('path/to/save/file/to.tif');
}$client->outbound->find(fax_id)->cancel();
A fax is cancelled via a method on the Interfax\Outbound\Fax model.
$fax = $client->outbound->find(123456);
if ($fax) {
$fax->cancel();
}$client->outbound->search($options)
Search for outbound faxes with a hash array of options keyed by the accepted search parameters for the outbound search API endpoint.
$faxes = $client->outbound->search(['faxNumber' => '+1230002305555']);
// Interfax\Outbound\Fax[]Options: ids, reference, dateFrom, dateTo, status, userId, faxNumber, limit, offset
$client->outbound->resend($id[,$newNumber])
Resend the fax identified by the given id (optionally to a new fax number).
$fax = $client->outbound->resend($id);
// Interfax\Outbound\Fax sent to the original number
$fax = $client->outbound->resend($id, $new_number);
// Interfax\Outbound\Fax sent to the $new_numberReturns a new Interfax\Outbound\Fax representing the newly created outbound fax.
Get list | Get record | Get image | Get emails | Mark as read | Resend to email
Interfax\Client has an inbound property that supports the API endpoints for receiving faxes, as described in the Documentation
$inbound = $client->inbound;
//Interfax\Inbound$inbound->incoming($options = []);
Retrieves a user's list of inbound faxes.
$faxes = $inbound->incoming();
//\Interfax\Inbound\Fax[]
$faxes = $inbound->incoming(['unreadOnly' => true ...]); // see docs for list of supported query params
//\Interfax\Inbound\Fax[]$inbound->find($id);
Retrieves a single fax's metadata (receive time, sender number, etc.).
$fax = $inbound->find(123456);
//\Interfax\Inbound\Fax || nullnull is returned if the resource is not found. Note that this could be because the user is not permissioned for the specific fax.
$inbound->find($id)->image()
The image is retrieved via a method on the inbound fax object.
$fax = $client->inbound->find(123456);
if ($fax) {
$image = $fax->image();
$image->save('path/to/save/file/to.pdf');
}$inbound->find($id)->emails()
The forwarding email details are retrieved via a method on the inbound fax object.
$fax = $client->inbound->find(123456);
if ($fax) {
$emails = $fax->emails(); // array structure of forwarding emails.
}The returned array is a reflection of the values returned from the emails endpoint of the REST API:
[
[
'emailAddress' => '[email protected]',
'messageStatus' => 0,
'completionTime' => '2012-0623T17 => 24 => 11'
],
//...
];$inbound->find($id)->markRead();
$inbound->find($id)->markUnread();
The inbound fax object provides methods to change the read status.
$fax = $client->inbound->find(123456);
if ($fax) {
$fax->markUnread(); // returns true
$fax->markRead(); //returns true
}$inbound->find($id)->resend();
The resend method is on the inbound fax object.
$fax = $client->inbound->find(123456);
if ($fax) {
$fax->resend();
}Create | Upload chunk | Properties | Cancel
The Interfax\Document class allows for the uploading of larger files for faxing. The following is an example of how one should be created:
$document = $client->documents->create('test.pdf', filesize('test.pdf'));
$stream = fopen('test.pdf', 'rb');
$current = 0;
while (!feof($stream)) {
$chunk = fread($stream, 500);
$end = $current + strlen($chunk);
$doc->upload($current, $end-1, $chunk);
$current = $end;
}
fclose($stream);$params = [...]; // see documentation for possible params
$document = $client->documents->create($filename, filesize($filename), $params);
// Interfax\Document$document->upload($start, $end, $data); // returns the document object.Note no verification of data takes place - an exception wil be raised if values do not match appropriately.
As per the documentation a Document has a number of properties which are accessible:
$document->status;
$document->fileName;
$document->refresh()->attributes();$document->location;
// or as returned by the API:
$document->uri;$document->cancel(); //returns the $document instance
Can be done prior to completion or afterward
The Interfax\Outbound\Fax class wraps the details of any fax sent, and is returned by most of the Outbound methods.
It offers several methods to manage or retrieve information about the fax.
// fluent methods that return the $fax instance
$fax->refresh(); // refreshes the data on the fax object
$fax->cancel(); // cancel the fax, returns true on success
$fax->hide(); // hides the faxes from the fax lists
$image = $fax->image(); // returns Interfax\Image
$new_fax = $fax->resend('+1111111'); // returns a new Interfax\Outbound\Fax
$fax->attributes(); // hash array of fax data properties - see details belowProperties on the Fax vary depending on which method call has been used to create the instance. Requesting a property that has not been received will raise a SPL \OutOfBoundsException
These are all accessible on a fax instance:
echo $fax->completionTime
echo $fax->duration
...Note values will all be returned as strings.
For convenience, a hash array of the properties can be retrieved
$fax->attributes();Status should always be available. The values of the status codes are Documented here
The incoming equivalent of the outbound fax class, the Interfax\Inbound\Fax class wraps the details of any incoming fax, and is returned by the Interfax\Inbound methods where appropriate.
// fluent methods that return the $fax instance for method chaining
$fax->refresh(); // reload properties of the inbound fax
$fax->markRead(); // mark the fax read - returns true or throws exception
$fax->markUnread(); // mark the fax unread - returns true or throws exception
$fax->resend();
$image = $fax->image(); // Returns a Interfax\Image for this fax
$email_array = $fax->emails(); // see below for details on the structure of this array
$fax->attributes(); // hash array of propertiesWhere methods support a hash array structure of query parameters, these will be passed through to the API endpoint as provided. This ensures that any future parameters that might be added will be supported by the API as is.
The only values that are manipulated are booleans, which will be translated to the text 'TRUE' and 'FALSE' as appropriate.
Any method call that involves a call to the Interfax RESTful API may throw an instance of Interfax\Exception\RequestException.
An exception is thrown for any requests that do not return a successful HTTP Status code. The goal of this Exception is to provide a convenience wrapper around information that may have been returned.
Certain responses from the API will provide more detail, and where this occurs, it will be appended to the message of the Exception.
try {
$interfax->deliver(...);
} catch (Interfax\Exception\RequestException $e) {
echo $e->getMessage();
// contains text detail that is available
echo $e->getStatusCode();
// the http status code that was received
throw $e->getWrappedException();
// The underlying Guzzle exception that was caught by the Interfax Client.

Functionality for the API in both versions of the library should be the same, and its therefore intended that the core code continues to be the same in both versions. The differences primarily exist to enable continuity of test coverage as PHP evolves (and phpunit evolves with it)
As such, the core functionality should be developed in a way that will work with PHP 5.6 and up, and be consistent in both versions. Usage of newer language features in PHP will not be accepted in the core code.
