What are some potential issues with handling keyboard bounce in PHP scripts?

Keyboard bounce can cause multiple keypress events to be triggered when a key is pressed once, leading to unintended actions or errors in PHP scripts. To handle keyboard bounce, you can implement a debounce function that delays the execution of the keypress event handler until a certain amount of time has passed since the last keypress. 

<?php

// Debounce function to handle keyboard bounce
function debounce($callback, $delay) {
    return function() use ($callback, $delay) {
        static $timeout = null;
        
        if ($timeout) {
            clearTimeout($timeout);
        }
        
        $args = func_get_args();
        
        $timeout = setTimeout(function() use ($callback, $args) {
            call_user_func_array($callback, $args);
        }, $delay);
    };
}

// Example usage of debounce function for keypress event handler
$handleKeypress = debounce(function() {
    // Handle keypress event here
}, 300); // Delay of 300 milliseconds

// Add keypress event listener
document.addEventListener('keypress', $handleKeypress);

?>
