How to use PHP and Google Sheets API to read, write and edit online documents

With the continuous innovation of Internet technology, more and more applications are beginning to develop in the direction of cloud storage and online collaboration. As a powerful online spreadsheet tool, Google Sheets has become one of the preferred tools for many businesses and teams to collaborate. The combination of PHP and Google Sheets API provides developers with a simple way to read, write and edit online documents. This article will introduce how to use PHP and Google Sheets API to read, write and edit online documents.

1. Brief description of Google Sheets API

Google Sheets API is a REST-based API that allows developers to read and modify Google Sheets spreadsheets programmatically. You can use the Google Sheets API to create new spreadsheets, copy and move spreadsheets, and add data to spreadsheets, among other functions. Using the Google Sheets API requires authentication using OAuth 2.0 authentication.

2. How PHP interacts with the Google Sheets API

The main steps to use PHP to connect to the Google Sheets API are as follows:

1. Create a Google Cloud Console project

Create a project in the Google Cloud Console and enable the Google Sheets API in APIs and Services. Additionally, you will need to use the Google Cloud Console to create an OAuth 2.0 client ID and obtain an API key and access token.

2. Install the Google API client library

You can use Composer to install the Google API client library. Execute the following command in the terminal:

composer require google/apiclient:^2.0

Additionally, you need to include the autoload file in the PHP file:

require __DIR__ . '/vendor/autoload.php';

3. Authentication

Use OAuth 2.0 Authentication for authentication. The specific process of authentication is as follows:

a. Create client object:

$client = new GoogleClient();

b. Set client ID and API key:

$client->setClientId('YOUR_CLIENT_ID');
$client->setClientSecret('YOUR_CLIENT_SECRET');
$client->setRedirectUri('YOUR_REDIRECT_URI');

c. Obtain authorization link:

$auth_url = $client->createAuthUrl();

d. Open the authorization link in the browser, log in with your Google account and authorize:

header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));

e. After successful authorization, an authorization code will be returned. Use the authorization code to obtain the access token:

$client->fetchAccessTokenWithAuthCode($_GET['code']);

4. Access Google Sheets API

After successful authentication, you can use the Google Sheets API to access, read and write spreadsheets. Editing is done. Here are some examples of basic API calls:

Get a list of spreadsheets:

$service = new Google_Service_Sheets($client);
$response = $service->spreadsheets->get($spreadsheet_id);
$sheets = $response->getSheets();
foreach ($sheets as $sheet) {
    echo $sheet->getProperties()->getTitle() . "
";
}

Read data from a spreadsheet:

$range = 'Sheet1!A2:C';
$response = $service->spreadsheets_values->get($spreadsheet_id, $range);
$values = $response->getValues();
if (empty($values)) {
    print "No data found.
";
} else {
    foreach ($values as $row) {
        printf("%s, %s, %s
", $row[0], $row[1], $row[2]);
    }
}

Add data to a spreadsheet:

$values = [
    ["John", "Doe", "johndoe@example.com"],
];
$body = new Google_Service_Sheets_ValueRange([
    'values' => $values
]);
$result = $service->spreadsheets_values->append($spreadsheet_id, $range, $body, [
    'valueInputOption' => 'USER_ENTERED'
]);
