How can headers be utilized to trigger a function with specific data in PHP when a link is clicked?

To trigger a function with specific data in PHP when a link is clicked, you can use headers to redirect the user to a specific PHP file that will process the data and execute the desired function. You can pass the data through query parameters in the URL and have the PHP file retrieve and process it accordingly. 

// Link click handler in your HTML file
<a href="process_data.php?data=example">Click here</a>

// process_data.php file
<?php
if(isset($_GET['data'])) {
    $data = $_GET['data'];
    
    // Call your function with the specific data
    yourFunction($data);
}
?>
