How to use Aspose.Cells Cloud SDK for PHP

Aspose.Cells Cloud PHP SDK is a powerful library that allows developers to manipulate and process Microsoft Excel files using the PHP programming language. With this SDK, you can create, edit, and convert Excel documents in the cloud, without installing additional software or dependencies on your local machine.

In this article, we will explore how to use the Aspose.Cells Cloud PHP SDK to perform common tasks such as creating a new workbook, inserting data into cells, and saving the modified workbook to the cloud.

Getting Started

Before you can start using the Aspose.Cells Cloud SDK for PHP, you need to prepare a few prerequisites:

Aspose Cloud account – sign up on the Aspose website.
client_id and client_secret – generate them from the Aspose Cloud console (see the Authentication guide).
Storage – decide whether to use Aspose Cloud storage or a custom storage solution and ensure it is accessible from your application.

Once the prerequisites are in place, you can set up your development environment.

How to install the PHP package for Aspose.Cells Cloud

You can install Aspose.Cells Cloud SDK for PHP. Below are the steps:

Add Aspose.Cells Cloud as a dependency to your composer.json file:

{
    "require": {
        "aspose/cells-cloud": "^24.3"
    }
}

Run Composer to install the SDK:
```
composer install
```
Include Composer’s autoloader in your PHP code:
```
require 'vendor/autoload.php';
```

How to use PHP package to convert XLSX to other formats

Import the Aspose.Cells Cloud library – load the classes you need.
Configure the API client with credentials – set client_id and client_secret.
Prepare conversion parameters – specify the source file, target format, and storage folder.
Execute workbook conversion – call postConvertWorkbook and handle the response.

Below is a complete, self‑contained example that demonstrates these steps, including basic error handling:

<?php
require 'vendor/autoload.php';

use Aspose\Cells\Cloud\Configuration;
use Aspose\Cells\Cloud\CellsApi;

// -------------------------------------------------
// 1. Configure credentials
// -------------------------------------------------
$config = Configuration::getDefaultConfiguration();
$config->setAppKey('YOUR_CLIENT_ID');      // replace with your client_id
$config->setAppSid('YOUR_CLIENT_SECRET'); // replace with your client_secret

// -------------------------------------------------
// 2. Initialise the API client
// -------------------------------------------------
$api = new CellsApi();

// -------------------------------------------------
// 3. (Optional) Upload a sample workbook to storage
// -------------------------------------------------
try {
    $uploadResponse = $api->uploadFile('sample.xlsx', file_get_contents('sample.xlsx'));
} catch (Exception $e) {
    echo "Upload error: " . $e->getMessage() . PHP_EOL;
}

// -------------------------------------------------
// 4. Convert the workbook to PDF
// -------------------------------------------------
try {
    $result = $api->postConvertWorkbook('sample.xlsx', 'pdf', null, null, null, null, null);
    // Save the converted file locally
    file_put_contents('sample.pdf', $result);
    echo "Conversion successful – file saved as sample.pdf" . PHP_EOL;
} catch (Exception $e) {
    echo "Conversion error: " . $e->getMessage() . PHP_EOL;
}
?>

Key points in the example

Configuration::getDefaultConfiguration() is used to inject your credentials.
postConvertWorkbook performs the conversion; the first argument is the source file name, and the second argument is the desired output format (pdf, csv, etc.).
A try … catch block demonstrates simple error handling for common HTTP errors such as 401 (unauthorized) or 404 (not found).
