How can PHP functions be called using links in a web page?

To call PHP functions using links in a web page, you can use query parameters in the URL to pass the function name and any necessary parameters. In the PHP code, you can check for these parameters and call the corresponding function dynamically. This allows you to trigger PHP functions by clicking on links on the web page. 

<?php
// Check if a function is specified in the URL
if(isset($_GET['function'])) {
    // Call the specified function
    $function_name = $_GET['function'];
    if(function_exists($function_name)) {
        call_user_func($function_name);
    }
}

// Sample PHP function to be called
function sample_function() {
    echo "This is a sample function called from a link!";
}
?>

<!-- Link to call the sample_function -->
<a href="?function=sample_function">Call Sample Function</a>
