Laravel

PostHog makes it easy to get data about traffic and usage of your Laravel app. Integrating PostHog enables analytics, custom events capture, feature flags, and more.

This guide walks you through integrating PostHog into your Laravel app using the PHP SDK.

Installation

First, ensure Composer is installed. Then run composer require posthog/posthog-php to install PostHog’s PHP SDK.

Next, initialize PostHog in the boot method of app/Providers/AppServiceProvider.php:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use PostHog\PostHog;

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        PostHog::init(
            '<ph_project_api_key>',
            [
                'host' => 'https://us.i.posthog.com'
            ]
        );
    }
}

You can find your project API key and instance address in your project settings.

Usage

To access your PostHog client anywhere in your app, import use PostHog\PostHog; and call PostHog::method_name. For example, below is how to capture an event in a simple route:

<?php

use Illuminate\Support\Facades\Route;
use PostHog\PostHog;

Route::get('/', function () {
    PostHog::capture([
        'distinctId' => 'distinct_id_of_your_user',
        'event' => 'route_called'
    ]);

    return view('welcome');
});
