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

    Capture custom events using the PostHog client:

    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
