PHP product analytics installation

1

Install the package

Required

Install the PostHog PHP library using Composer:

Terminal

composer require posthog/posthog-php

2

Configure PostHog

Required

Initialize the PostHog client with your API key and host:

PHP
PostHog\PostHog::init(
    '<ph_project_api_key>',
    ['host' => 'https://us.i.posthog.com']
);

3

Send events

Optional

Once installed, you can manually send events to test your integration:

PHP
PostHog::capture([
    'distinctId' => 'test-user',
    'event' => 'test-event',
]);

By default, for backwards compatibility reasons, events are sent with person profile processing enabled. This means a person profile will be created for each user who triggers an event.

If you want to disable person profile processing for certain events, send the event with the following property:

PHP
'$process_person_profile' => false
