What is the common practice for opening a link in a new window and updating a counter using PHP?

When opening a link in a new window and updating a counter using PHP, you can achieve this by using JavaScript to open the link in a new window and then sending an AJAX request to a PHP script to update the counter. This way, the link will open in a new window while the counter is updated in the background. 

// PHP code to update counter
if(isset($_POST['link_id'])){
    $link_id = $_POST['link_id'];
    
    // Update counter logic here
    
    echo "Counter updated for link with ID: " . $link_id;
}
```

```javascript
// JavaScript code to open link in new window and update counter
function openLinkAndUpdateCounter(linkId) {
    window.open('http://www.example.com/link', '_blank');
    
    var xhr = new XMLHttpRequest();
    xhr.open('POST', 'update_counter.php', true);
    xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    xhr.send('link_id=' + linkId);
}
