You can enable App and API Protection for PHP services with the following setup options:

1. If your PHP service already has APM tracing set up and running, then skip to service configuration
1. If your PHP service doesn't have APM tracing set up, you can easily enable App and API Protection with Datadog's [Automatic Installation](https://docs.datadoghq.com/tracing/trace_collection/automatic_instrumentation/single-step-apm/docker/)
1. Otherwise, keep reading the following manual setup instructions

{% /alert %}

## Overview{% #overview %}

App and API Protection leverages the [Datadog PHP library](https://github.com/DataDog/dd-trace-php/) to monitor and secure your PHP service. The library integrates seamlessly with your existing application without requiring code changes.

For detailed compatibility information, including supported PHP versions, frameworks, and deployment environments, see [PHP Compatibility Requirements](https://docs.datadoghq.com/security/application_security/setup/php/compatibility).

This guide explains how to set up App and API Protection (AAP) for PHP applications. The setup involves:

1. Installing the Datadog Agent
1. Enabling App and API Protection monitoring
1. Running your PHP application with the Datadog Agent
1. Verifying the setup

## Prerequisites{% #prerequisites %}

- Docker installed on your host
- PHP application containerized with Docker
- Your Datadog API key
- Datadog PHP tracing library (see [version requirements](https://docs.datadoghq.com/security/application_security/setup/php/compatibility))

## 1. Installing the Datadog Agent

Install the Datadog Agent by following the [setup instructions for Docker](https://docs.datadoghq.com/agent/?tab=cloud_and_container).

## 2. Enabling App and API Protection monitoring
If your PHP service already has APM tracing set up and running, you can automatically enable App and API Protection through Remote ConfigurationIf not, enable App and API Protection with the manual configuration instructions.navigation-menu{background:#f8f9fa;border:1px solid #e9ecef;border-radius:8px;padding:20px;margin:20px 0}.nav-container h3{margin-top:0;margin-bottom:15px;color:#333;font-size:1.1em}.nav-list{list-style:none;padding:0;margin:0}.nav-list li{margin-bottom:8px}.nav-list a{color:#06c;text-decoration:none;font-weight:500}.nav-list a:hover{text-decoration:underline;color:#049}
### Automatically enabling App and API Protection through Remote Configuration{% #automatically-enabling-app-and-api-protection-through-remote-configuration %}

You can enable services with remote configuration on your [services dashboard](https://app.datadoghq.com/security/configuration/asm/setup?services=recommended). Check the box for the service you want to enable App and API Protection for under Activate on your APM services.

### Manually enabling App and API Protection monitoring{% #manually-enabling-app-and-api-protection-monitoring %}

{% collapsible-section %}
#### APM Tracing Enabled

Add the following to your Dockerfile:

```dockerfile
# Install dd-trace-php
RUN curl -LO https://github.com/DataDog/dd-trace-php/releases/latest/download/datadog-setup.php
RUN php datadog-setup.php --php-bin=all
# Enable appsec
ENV DD_APPSEC_ENABLED=true
# Configure your service
ENV DD_SERVICE=<YOUR_SERVICE_NAME>
ENV DD_ENV=<YOUR_ENVIRONMENT>
```

{% /collapsible-section %}

{% collapsible-section %}
#### APM Tracing Disabled

To disable APM tracing while keeping App and API Protection enabled, you must set the APM tracing variable to false.

Add the following to your Dockerfile:

```dockerfile
# Install dd-trace-php
RUN curl -LO https://github.com/DataDog/dd-trace-php/releases/latest/download/datadog-setup.php
RUN php datadog-setup.php --php-bin=all
# Enable appsec
ENV DD_APPSEC_ENABLED=true
# Disable apm
ENV DD_APM_TRACING_ENABLED=false
# Configure your service
ENV DD_SERVICE=<YOUR_SERVICE_NAME>
ENV DD_ENV=<YOUR_ENVIRONMENT>
```

{% /collapsible-section %}

## 3. Run your application

Build your image and then run your container.

When running your container, ensure you do the following:

1. Connect the container to the same Docker network as the Datadog Agent.
1. Set the required environment variables.

```bash
docker run -d \
  --name your-php-app \
  your-php-app-image
```

## 4. Verify setup

To verify that App and API Protection is working correctly:

1. Send some traffic to your application.
1. Check for security signals and vulnerabilities in the [Application Signals Explorer](https://app.datadoghq.com/security/appsec) in Datadog.
