❄️ PHP Snowplow Referer Parser

A modern PHP implementation of referer-parser, the library for extracting traffic data from referer (sic) URLs.

The implementation uses a JSON version of the shared database of known referers found in referers.yml.

🔱 Maintained PHP 8.2+ fork of php-referer-parser by Lars Strojny, with automatic data updates.

✨ Key Features

• 🌍 Parse referer URLs into structured attribution data
• 🧭 Identify traffic source and medium (search, social, email, etc.)
• 📝 Extract search terms from supported search engines
• 📦 Based on Snowplow’s shared referer database
• ⚡ Modern PHP 8.2+ implementation
• 🔁 Regularly updated referer data

🧩 Requirements

• PHP ≥ 8.2

📦 Installation

composer require simplestats/referer-parser

    'http:/www.psychicbazaar.com/shop'
);

if ($referer->isKnown()) {
    echo $referer->medium;     // Medium::SEARCH
