This is a lightweight wrapper for the CloudConvert API.

Feel free to use, improve or modify this wrapper! If you have questions contact us or open an issue on GitHub.

Quickstart

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;
$api = new Api("your_api_key");

$api->convert([
        'inputformat' => 'png',
        'outputformat' => 'pdf',
        'input' => 'upload',
        'file' => fopen('./tests/input.png', 'r'),
    ])
    ->wait()
    ->download('./tests/output.pdf');
?>

You can use the CloudConvert API Console to generate ready-to-use PHP code snippets using this wrapper.

Install with Composer

To download this wrapper and integrate it inside your PHP application, you can use Composer.

Add the repository in your composer.json file or, if you don't already have this file, create it at the root of your project with this content:

{
    "name": "Example Application",
    "description": "This is an example",
    "require": {
        "cloudconvert/cloudconvert-php": "dev-master"
    }
}

Then, you can install CloudConvert APIs wrapper and dependencies with:

php composer.phar install

This will install cloudconvert/cloudconvert-php to ./vendor, along with other dependencies including autoload.php.

Install manually

If you don't want to use composer, you can download the cloudconvert-php.phar release from the Releases tab on GitHub. The .phar file is basically a ZIP file which contains all dependencies and can be used as shown here:

<?php
require 'phar://cloudconvert-php.phar/vendor/autoload.php';
use \CloudConvert\Api;
$api = new Api("your_api_key");

//...

Using with Callback

This is a non-blocking example for server side conversions: The public URL of the input file and a callback URL is sent to CloudConvert. CloudConvert will trigger this callback URL if the conversion is finished.

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;
$api = new Api("your_api_key");

$process = $api->createProcess([
    'inputformat' => 'png',
    'outputformat' => 'jpg',
]);

$process->start([
    'outputformat' => 'jpg',
    'converteroptions' => [
        'quality' => 75,
    ],
    'input' => 'download',
    'file' => 'https://cloudconvert.com/blog/wp-content/themes/cloudconvert/img/logo_96x60.png',
    'callback' => 'http://_INSERT_PUBLIC_URL_TO_/callback.php'
]);

echo "Conversion was started in background :-)";
?>

Using the following callback.php you can retrieve the finished process and download the output file.

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;
use \CloudConvert\Process;
$api = new Api("your_api_key");

$process = new Process($api, $_REQUEST['url']);
$process->refresh()->download("output.jpg");

?>

User uploaded input files

If your input files are provided by your users, you can let your users directly upload their files to CloudConvert (instead of uploading them to your server first and afterwards sending them to CloudConvert). The following example shows how this can be implemented easily.

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;
$api = new Api("your_api_key");

$process = $api->createProcess([
    'inputformat' => 'png',
    'outputformat' => 'jpg',
]);

$process->start([
    'input' => 'upload',
    'outputformat' => 'jpg',
    'converteroptions' => [
        'quality' => 75,
    ],
    'callback' => 'http://_INSERT_PUBLIC_URL_TO_/callback.php'
]);
?>
<form action="<?=$process->upload->url?>" method="POST" enctype="multipart/form-data">
     <input type="file" name="file">
     <input type="submit">
</form>

Download of multiple output files

In some cases it might be possible that there are multiple output files (e.g. converting a multi-page PDF to JPG). You can download them all to one directory using the downloadAll() method.

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;
$api = new Api("your_api_key");

$process = $api->convert([
        'inputformat' => 'pdf',
        'outputformat' => 'jpg',
        'converteroptions' => [
            'page_range' => '1-3',
        ],
        'input' => 'download',
        'file' => fopen('./tests/input.pdf', 'r'),
    ])
    ->wait()
    ->downloadAll('./tests/');
?>

Alternatively you can iterate over $process->output->files and download them seperately using $process->download($localfile, $remotefile).

Catching Exceptions

The following example shows how to catch the different exception types which can occur at conversions:

<?php
require __DIR__ . '/vendor/autoload.php';
use \CloudConvert\Api;

$api = new Api("your_api_key");

try {

    $api->convert([
        'inputformat' => 'pdf',
        'outputformat' => 'jpg',
        'input' => 'upload',
        'file' => fopen('./tests/input.pdf', 'r'),
    ])
        ->wait()
        ->downloadAll('./tests/');

} catch (\CloudConvert\Exceptions\ApiBadRequestException $e) {
    echo "Something with your request is wrong: " . $e->getMessage();
} catch (\CloudConvert\Exceptions\ApiConversionFailedException $e) {
    echo "Conversion failed, maybe because of a broken input file: " . $e->getMessage();
}  catch (\CloudConvert\Exceptions\ApiTemporaryUnavailableException $e) {
    echo "API temporary unavailable: " . $e->getMessage() ."\n";
    echo "We should retry the conversion in " . $e->retryAfter . " seconds";
} catch (Exception $e) {
    // network problems, etc..
    echo "Something else went wrong: " . $e->getMessage() . "\n";
}

How to build the documentation?

Documentation is based on phpdocumentor. To install it with other quality tools, you can install local npm project in a clone a project

git clone https://github.com/LunawebLtd/cloudconvert-php.git
cd cloudconvert-php
php composer.phar install
npm install

To generate documentation, it's possible to use directly:

grunt phpdocs

Documentation is available in docs/ directory.

How to run tests?

Tests are based on phpunit. To install it with other quality tools, you can install local npm project in a clone a project

git https://github.com/LunawebLtd/cloudconvert-php.git
cd cloudconvert-php
php composer.phar install
npm install

Edit phpunit.xml file with your API Key to pass functionals tests. Then, you can run directly unit and functionals tests with grunt.

grunt
