Introduction

The RPurinton Gmail Library is a PHP library designed to facilitate interaction with Gmail using Google's API. It provides functionality for sending, receiving, and managing Gmail messages efficiently.

Installation

Composer Installation

To install the library, use Composer:

composer require rpurinton/gmail

Configuration Setup

1. Create a config directory at the same level as the vendor directory.
2. Place the Gmail.json file with your credentials in the config directory.
   • Note: The access_token, refresh_token, and expires_at will be added later by the library.

Google Cloud Project Setup

1. Create a Google Cloud project.
2. Enable the Gmail API.
3. Create OAuth 2.0 credentials.
4. Download the credentials JSON file and place it in the config directory as Gmail.json.

Usage

Initialization

• Create a new instance of the Gmail class.
• Run the ->init() method to start the OAuth2 authentication flow.
• This method will redirect to Google for authentication and back to your script with the authorization code.
• The init() method is crucial for the first-time setup to obtain the access_token and refresh_token.
• These tokens are stored in the Gmail.json configuration file.
• Once the tokens are obtained, the init() method is not required again unless the user deauthorizes the app from their Gmail account.

API Methods

• send(): Send an email with optional attachments, CC, and BCC.
• list(): List messages based on a query and maximum results.
• read(): Retrieve a specific message by ID.
• delete(): Delete messages in batch.
• getAttachmentIds(): Retrieve attachment IDs from a message.

Examples

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

use RPurinton\Gmail\Gmail;

$gmail = new Gmail();
$gmail->init(); // Only needed for the first-time setup

// Example to send an email
$gmail->send('from@example.com', ['to@example.com'], 'Subject', 'Email body');

Troubleshooting

• Ensure that the Gmail.json file is correctly configured and accessible.
• Verify that the Google Cloud project is set up with the correct credentials and permissions.
• If you encounter issues with token expiration, ensure the refresh_token is valid and the init() method was successfully executed initially.
