How can PHP handle data after the "#" symbol in a URL?

When data is passed after the "#" symbol in a URL, it is referred to as the fragment identifier. This data is not sent to the server by the browser, so PHP cannot directly access it. However, you can use JavaScript to read the fragment identifier and send it to the server using AJAX to process the data in PHP. 

// JavaScript code to send the fragment identifier data to the server using AJAX
<script>
    var fragmentData = window.location.hash.substr(1);
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            console.log(this.responseText);
        }
    };
    xhttp.open("GET", "process_data.php?fragmentData=" + fragmentData, true);
    xhttp.send();
</script>

// PHP code in process_data.php to handle the data passed after the "#" symbol
<?php
    $fragmentData = $_GET['fragmentData'];
    // Process the fragment data as needed
    echo "Data received: " . $fragmentData;
?>
