How can developers ensure proper functionality and performance when dynamically loading CSS and JavaScript files in PHP?

When dynamically loading CSS and JavaScript files in PHP, developers should ensure that the files are loaded in the correct order and that there are no conflicts between them. One way to achieve this is by using dependency management tools or frameworks like webpack or gulp to bundle and minify the files before loading them. Additionally, developers should regularly test the functionality and performance of the dynamically loaded files to identify and address any issues. 

<?php
function load_css($files) {
    foreach($files as $file) {
        echo '<link rel="stylesheet" type="text/css" href="' . $file . '">';
    }
}

function load_js($files) {
    foreach($files as $file) {
        echo '<script src="' . $file . '"></script>';
    }
}

$css_files = ['style.css', 'bootstrap.css'];
$js_files = ['script.js', 'jquery.js'];

load_css($css_files);
load_js($js_files);
?>
