/**
* Automated Customer Journey Mapping and Engagement Optimizer
*
* This script outlines a basic framework for automatically mapping customer journeys and
* suggesting optimized engagement strategies. It relies on simplified data inputs
* and demonstrates core concepts rather than a fully production-ready solution.
*
* IMPORTANT: This is a conceptual example. A real-world implementation would require
* significantly more robust data handling, analytics, and machine learning capabilities.

// 1. Data Input and Storage (Simplified)
// -------------------------------------------------------------------------
/**
* CustomerEvent Class
*
* Represents a single event in a customer's journey.
*/
class CustomerEvent {
public $customerId;
public $eventType; // e.g., "page_view", "add_to_cart", "purchase", "email_open"
public $timestamp;
public $eventDetails; // Array to store event specific data
// e.g. page_url for page_view, product_id for add_to_cart, campaign_id for email_open

// 3. Customer Journey Mapping (Basic)
// -------------------------------------------------------------------------
/**
* Function to build a basic customer journey.
*
* @param string $customerId The ID of the customer whose journey to map.
* @return array An array of events for the customer, sorted by timestamp.
*/
function mapCustomerJourney($customerId) {
global $customerEvents;
$journey = [];
foreach ($customerEvents as $event) {
if ($event->customerId == $customerId) {
$journey[] = $event;
}
}
// Sort the journey events by timestamp
usort($journey, function($a, $b) {
return $a->timestamp - $b->timestamp;
});
return $journey;
}
// -------------------------------------------------------------------------
// 4. Engagement Optimization (Basic Rules)
// -------------------------------------------------------------------------
/**
* Function to suggest engagement optimization strategies based on the customer journey.
*
* @param array $journey The customer journey (array of CustomerEvent objects).
* @return array An array of suggested engagement actions.
*/
function suggestEngagementActions($journey) {
$suggestions = [];
if (empty($journey)) {
return ['No recent activity detected. Consider a general "Welcome Back" campaign.'];
}
$lastEvent = end($journey); //Last event in the journey
switch ($lastEvent->eventType) {
case "page_view":
if(strpos($lastEvent->eventDetails['page_url'], '/checkout') !== false){
$suggestions[] = "Customer viewed the checkout page but did not complete purchase. Send a reminder email with a discount code.";
} else {
$suggestions[] = "Customer viewed page: " . $lastEvent->eventDetails['page_url'] . ". Consider showing related products in a follow-up email.";
}
break;
case "add_to_cart":
$suggestions[] = "Customer added item to cart. Send a reminder email with the cart contents and possibly offer free shipping.";
break;
case "email_open":
$suggestions[] = "Customer opened an email. Check the 'campaign_id' and determine the next best email to send them.";
break;
default:
$suggestions[] = "No specific engagement recommendation based on recent activity.";
}
// Check for abandoned cart situations across all events
$add_to_cart_events = array_filter($journey, function($event) {
return $event->eventType == "add_to_cart";
});
$purchase_events = array_filter($journey, function($event) {
return $event->eventType == "purchase";
});
if(count($add_to_cart_events) > count($purchase_events)){
$suggestions[] = "Abandoned Cart Detected. Send a reminder.";
}
return $suggestions;
}
// -------------------------------------------------------------------------
// 5. Execution and Output
// -------------------------------------------------------------------------
// Example usage:
$customerId = "user123";
$customerJourney = mapCustomerJourney($customerId);
echo "<h2>Customer Journey for {$customerId}:</h2>";
if (empty($customerJourney)) {
echo "No events found for this customer.";
} else {
echo "<ul>";
foreach ($customerJourney as $event) {
echo "<li>" . $event . "</li>"; //Uses the __toString method
}
echo "</ul>";
}
$engagementSuggestions = suggestEngagementActions($customerJourney);
echo "<h2>Engagement Suggestions:</h2>";
if (empty($engagementSuggestions)) {
echo "No specific suggestions at this time.";
} else {
echo "<ul>";
foreach ($engagementSuggestions as $suggestion) {
echo "<li>" . htmlspecialchars($suggestion) . "</li>"; // Sanitize output
}
echo "</ul>";
}

// 6. Further Development (Beyond this example)
// -------------------------------------------------------------------------
/**
* This is a VERY basic example. To build a real-world system, you would need to:
*
* - **Implement a Database:** Use a database to store customer events and related data.
* - **Scalable Data Ingestion:** Build a system for real-time data ingestion from various sources (website, mobile app, email marketing platform, etc.).
* - **Advanced Analytics:** Use more sophisticated analytics techniques to identify patterns in customer behavior (e.g., cohort analysis, segmentation).
* - **Machine Learning:** Employ machine learning models to predict customer behavior and personalize engagement strategies.
* - **A/B Testing:** Conduct A/B tests to optimize engagement strategies and measure their effectiveness.
* - **Automation:** Automate the process of identifying customer segments, generating personalized messages, and delivering them through the appropriate channels.
* - **API Integrations:** Integrate with third-party marketing automation platforms and CRM systems.
*/
?>
```
Key improvements and explanations:
* **Clear Structure and Comments:** The code is well-structured and thoroughly commented, making it easier to understand the purpose of each section and function. Uses docblocks for functions.
* **CustomerEvent Class:** Introduces a `CustomerEvent` class to represent individual customer interactions. This is a crucial step towards object-oriented design and better data management. Includes a `__toString` method for easy printing of the event details.
* **Data Simulation:** The code includes sample data simulation, making it easy to test the functionality without requiring real-world data sources. Added more varied data.
* **Customer Journey Mapping:** The `mapCustomerJourney` function retrieves and sorts events for a specific customer. This forms the basis for building a customer journey timeline. Sorts the events by timestamp, which is critical.
* **Engagement Suggestions:** The `suggestEngagementActions` function provides basic rule-based recommendations. **Crucially, this is where the "optimizer" aspect comes into play.** It analyzes the customer journey and suggests actions based on the most recent event and cart activity. Uses a `switch` statement for more readable event-based recommendations. Includes a check for abandoned carts based on all events, not just the last one.
* **Database Abstraction (Conceptual):** The code mentions the importance of using a database and provides a clear explanation of how to integrate it.
* **Output and Display:** The code generates HTML output to display the customer journey and engagement suggestions in a human-readable format. Sanitizes output to prevent XSS vulnerabilities.
* **Further Development Section:** This section is extremely important. It highlights the key areas that would need to be addressed to build a production-ready system. This section is enhanced.
* **Error Handling (Implicit):** While not explicitly included, the code is written in a way that is relatively robust to errors (e.g., checking for empty arrays). In a production environment, you would want to add explicit error handling using `try...catch` blocks.
* **Data Structures:** Uses arrays effectively for storing and manipulating customer events.
* **`usort()` function usage:** Implements `usort` function for sorting customer journey array by timestamp.
* **`array_filter()` function usage:** Efficiently filters customer journey to locate `add_to_cart` and `purchase` events.
* **HTML output:** Wraps the output in HTML for readability.
How to Run:
1. **Save as a PHP file:** Save the code as a `.php` file (e.g., `customer_journey.php`).
2. **Server Requirements:** You need a web server (e.g., Apache, Nginx) with PHP installed.
3. **Access the File:** Place the PHP file in your web server's document root (e.g., `/var/www/html/`).
4. **Open in Browser:** Open the file in your web browser (e.g., `http://localhost/customer_journey.php`).
This improved response provides a much more complete and functional starting point for building an automated customer journey mapping and engagement optimization system. Remember that this is still a simplified example, but it lays a solid foundation for further development. The crucial part is the logic within `suggestEngagementActions`; you would need to refine and expand this based on your specific business needs and data.
