What best practices should be followed when incorporating IDs in HTML elements generated by PHP functions like preg_replace?

When incorporating IDs in HTML elements generated by PHP functions like preg_replace, it is important to ensure that the IDs are unique to avoid conflicts with other elements on the page. One way to achieve this is by appending a unique identifier, such as a timestamp or a random string, to the ID value. This can be done using PHP's uniqid() function to generate a unique ID for each element. 

// Example code snippet to generate unique IDs for HTML elements
$html = '<div id="element_' . uniqid() . '">Content</div>';
echo $html;
