What are some common pitfalls to avoid when trying to execute a function upon window closure in PHP?

One common pitfall when trying to execute a function upon window closure in PHP is relying solely on client-side JavaScript events, as they may not always be triggered (e.g., if the browser crashes). To ensure the function is executed reliably, you can use a combination of JavaScript to trigger an AJAX request to a PHP script that performs the desired action. 

// JavaScript code to trigger AJAX request on window closure
<script>
window.onbeforeunload = function() {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', 'execute_function.php', false);
    xhr.send();
};
</script>

// PHP script (execute_function.php) to perform the desired action
<?php
// Perform the desired action here
?>
