How does the PHP5 code snippet provided in the thread improve the Impressions-Counter functionality?

The issue with the Impressions-Counter functionality is that it is not incrementing the counter value properly. To solve this issue, we need to modify the PHP code snippet to correctly increment the counter value each time the page is visited. 

// PHP code snippet to improve Impressions-Counter functionality
// Initialize counter variable
$counter = 0;

// Check if counter value is stored in session
if(isset($_SESSION['counter'])){
    // Retrieve counter value from session
    $counter = $_SESSION['counter'];
}

// Increment counter value
$counter++;

// Store updated counter value in session
$_SESSION['counter'] = $counter;

// Display counter value
echo "Impressions: " . $counter;
