# PHP

Integrate Mailtrap with PHP applications using SDK, SMTP, or RESTful API for reliable email sending

<a href="https://github.com/mailtrap/mailtrap-php" class="button primary">Mailtrap PHP SDK on GitHub</a>

### Overview

Mailtrap can be integrated with PHP apps and projects for email sending.

### Email API/SMTP for PHP

#### SDK integration

The [Mailtrap PHP SDK](https://github.com/mailtrap/mailtrap-php) is a modern, type-safe library for sending transactional and bulk emails from PHP applications. The SDK supports:

* Transactional email sending
* Batch email sending
* Dedicated <i class="fa-laravel">:laravel:</i> [**Laravel**](https://github.com/mailtrap/mailtrap-php/tree/main/src/Bridge/Laravel) and <i class="fa-symfony">:symfony:</i> [**Symfony**](https://github.com/mailtrap/mailtrap-php/tree/main/src/Bridge/Symfony) bridges
* Template management
* Contact management
* Sandbox testing
* Account management

Additionally, you can watch the [course released by Symfony Casts](https://symfonycasts.com/screencast/mailtrap) for a step-by-step integration walkthrough.

### Installation

Install the SDK using Composer:

{% code title="Composer" %}

```bash
composer require railsware/mailtrap-php
```

{% endcode %}

### Minimal Example

Here's a minimal example to send your first email:

{% code title="send\_email.php" %}

```php
<?php

use Mailtrap\Helper\ResponseHelper;
use Mailtrap\MailtrapClient;
use Mailtrap\Mime\MailtrapEmail;
use Symfony\Component\Mime\Address;

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

$mailtrap = MailtrapClient::initSendingEmails(
    apiKey: getenv('MAILTRAP_API_KEY') // your API key here https://mailtrap.io/settings/api-tokens
);

$email = (new MailtrapEmail())
    ->from(new Address('sender@example.com'))
    ->to(new Address('recipient@example.com'))
    ->subject('Hello from Mailtrap PHP')
    ->text('Plain text body');

$response = $mailtrap->send($email);

// Access response body as array (helper optional)
var_dump(ResponseHelper::toArray($response));
```

{% endcode %}

{% hint style="info" %}
Get your API token from your Mailtrap account under **Settings → API Tokens**.
{% endhint %}

#### SMTP integration

To integrate SMTP with your PHP app, navigate to the **Integrations** tab, choose the desired PHP framework, and copy-paste the credentials or ready-made code snippets.

{% hint style="info" %}
SMTP integration is compatible with any PHP framework or library that sends emails via SMTP.
{% endhint %}

#### RESTful API integration

To integrate Mailtrap using RESTful API, use the configuration available among **Code samples** under the API section.

API integration can be used with any PHP framework or library that supports HTTP requests. For more details, refer to the [API documentation](https://api-docs.mailtrap.io/docs/mailtrap-api-docs/5tjdeg9545058-mailtrap-api).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.mailtrap.io/guides/sdk/php-integration.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
